When a pipe leaks or a shower line fails, it isn't just an annoyance — it's a cascade of costs, time, and stress. Picking the right plumbing fittings and supports up front helps prevent leaks, reduces noise, and keeps your system running smoothly for years. Think of fittings as the joints of a body and supports as the skeleton: the right combination keeps everything aligned and healthy.
That vague “other” label actually includes a wide range of hardware: couplings, adapters, elbow fittings, tees, unions, reducers, compression fittings, hangers, pipe clamps, straps, insulation clips, and specialty connectors for appliances and fixtures. You’ll also find brackets for water heater lines, seismic straps for gas piping, and vibration isolators that cut down on rattle. Each small piece plays a key role in strength, flexibility, and longevity.
Not all suppliers are created equal. Some specialize in pro-grade materials, others focus on DIY-friendly kits and convenience. Below I highlight trusted US retailers and wholesalers where you can find a broad selection of plumbing fittings and pipe supports, with quick notes on what they’re best for.
The Home Depot is a go-to for DIYers and pros alike, offering a wide range of brass, copper, PVC, and PEX fittings in both retail stores and online. If you want immediate pickup or same-day convenience, their stores are easy to access. They carry brands like SharkBite for tool-free connections and have a solid selection of pipe hangers and supports in the plumbing aisle.
Lowe’s competes closely with Home Depot, often carrying similar brands and sizes. They’re strong on household plumbing supplies — think shower arm fittings, sink trap adapters, and galvanized straps — and their online inventory makes it easy to compare materials and prices. If you like straightforward product comparisons and in-store pickup, Lowe’s is worth checking.
Ferguson is a major wholesale distributor that professionals often prefer. They stock heavy-duty fittings, commercial-grade supports, and a deep inventory of copper, iron, and specialty components. If you’re working on a large remodel or need specific NFPA or ASME-compliant pieces, Ferguson’s pro-focused catalog makes sourcing easier.
SupplyHouse is an online supplier that caters to both tradespeople and advanced DIYers, offering a massive catalog of fittings, hangers, and niche parts. What I like about SupplyHouse is the depth: obscure adapter sizes, large-diameter supports, and compatible parts for hydronic systems are easy to find. Fast search filters help when you know the exact diameter in inches or the material you need.
Grainger is popular for industrial-grade fittings and supports, especially when you need robust clamps, vibration mounts, or stainless-steel hardware. Their catalog focuses on reliability under heavy use — a good pick when durability is a top priority and you’re dealing with high-pressure systems or corrosive environments.
Ace is neighborhood-friendly and great for quick fixes. They often stock common sizes like 1/2 inch and 3/4 inch fittings and a good selection of pipe straps and hangers. If you want friendly advice and a quick replacement part without trekking to a big-box store, Ace is a convenient option.
Menards is another big-box option strong in both price and variety, particularly in the Midwest. They carry PEX systems, PVC fittings, and a solid lineup of supports for residential applications. Prices can be competitive, and they often have seasonal promotions on plumbing essentials.
Build.com is great for finding specialty fittings, high-end finishes, and unusual connectors you won’t find at the average hardware store. Their online platform helps you source matching parts for faucets, showers, and under-sink systems, which is handy when you’re working to a design spec.
True Value stores are locally operated and handy for quick replacement parts, especially when you need a 1-inch coupling or a specific hanger on short notice. Local shop owners often have practical advice and can point you to the exact size you’ll need based on pipe diameter and material.
Amazon is useful for convenience and bulk ordering, especially if you already know the exact fittings you need. You’ll find everything from cheap universal fittings to pro-grade stainless steel clamps. Be cautious about seller reputation and product reviews — verify dimensions (in inches) and materials before you buy.
Each material has pros and cons. Brass and copper are traditional and reliable for water lines; PVC is common for drains and vents; PEX is flexible and fast to install; stainless steel shines where corrosion resistance is critical. Match material to application: you wouldn’t use PVC for a hot-water line inside a water heater, and you wouldn’t pick soft PEX clamps for a corrosive outdoor environment.
Brass fittings offer durability and corrosion resistance; copper pipe systems have proven longevity. These are common in hot-water and visible installations where heat tolerance and robust joints matter.
PVC is inexpensive and great for drain-waste-vent lines; CPVC tolerates higher temperatures so it’s sometimes used for hot-water branches. Remember, PVC fittings require solvent cement, while CPVC needs the proper grade of cement.
PEX tubing and fittings speed up installs and reduce the number of joints. They flex, which helps in tight spaces, and require compatible compression or crimp-style fittings. Use PEX for radiant floors and most household water lines.
Stainless fittings and supports are best where corrosion, salt air, or chemicals are concerns — think coastal homes, commercial kitchens, or outdoor systems. They last, but cost more upfront.
Measuring correctly avoids cringe-worthy returns and poor fits. Always measure pipe diameter in inches. For threaded pipes, you’ll measure nominal pipe size, not the outside diameter. When installing supports, think in feet: typical spacing for copper water lines is 6 to 8 feet; for PVC drain lines, supports every 3 to 4 feet help maintain slope.
Residential water lines commonly use 1/2 inch and 3/4 inch sizes. Larger mains might be 1 inch or more. For drains, 1-1/2 inch and 2 inch are common for sink and shower waste, with toilet drains commonly at 3 inches or larger. Always verify the nominal size before ordering fittings.
Support spacing depends on pipe material: for horizontal copper water lines, place hangers every 6 to 8 feet; for PEX, every 32 to 40 inches when horizontal; for PVC drain lines, every 3 to 4 feet to preserve slope. These are general guidelines — check local code for precise rules.
Supports distribute weight and prevent sagging — they’re the unsung heroes of plumbing. Hangers work well for suspending pipes from ceilings, clamps secure vertical runs, and straps fasten pipes to studs. For thermostatic or heavy systems (like water heaters), seismic straps and heavy-duty brackets may be required.
Hangers cradle pipes and allow slight movement; clamps tend to be tighter and prevent rotation. For long horizontal runs, hangers spaced in feet help keep alignment. For vertical sections or where motion is limited, choose a secure clamp.
Insulating inserts protect plastic pipes from metal-to-metal contact and reduce noise. Vibration mounts are used near pumps or mechanical equipment to cut down on resonance that can travel along pipe runs.
Install with patience. Clean and deburr cut pipe ends so fittings seat fully; check for correct insertion depth, especially with push-fit or compression fittings. Tighten unions and threaded connections to manufacturer torque specs — too loose causes leaks; too tight can crack fittings.
Push-fit fittings (like SharkBite) are fast and foolproof for many repair jobs, but ensure the pipe is fully inserted past the stop. Compression fittings are great for copper and metal-to-metal joints but require the nut and ferrule to be tightened evenly.
For threaded metal fittings, wrap pipe thread tape clockwise around the male threads to ensure a good seal. Use the right tape thickness for the diameter and avoid overuse that prevents threads from seating properly.
Buying the cheapest parts can cost you later. Instead, balance cost and quality: use bulk pack fittings for common sizes like 1/2 inch and 3/4 inch, shop seasonal sales at big-box stores, and consider slightly higher-grade materials where corrosion or heat is a factor. Buying a trusted brand in moderately priced materials often beats ultra-cheap parts that fail early.
If you’re tackling a whole-house re-pipe or a multi-point project, buy common fittings in bulk. For specialty items, compare Build.com, SupplyHouse, and Ferguson — you’ll often find pro-grade parts at reasonable wholesale prices.
Local plumbing codes dictate certain materials and installation methods. For instance, in some areas CPVC isn’t allowed for main hot-water lines, and seismic restraints are required in earthquake-prone zones. Consider water-saving fittings like low-flow trap assemblies and corrosion-resistant materials to extend the system’s life and lower environmental impact.
Use lead-free brass and certified fittings for potable water systems. Many states require NSF/ANSI-certification for materials that contact drinking water, so look for those labels when buying connectors and valves.
Simple changes like replacing a worn trap, adding a hose bib, or swapping a shower elbow are often DIY-friendly. But if you’re altering main supply lines, working on gas piping, or dealing with pressurized iron systems, call a licensed plumber. Safety, code compliance, and long-term performance are worth the pros’ expertise.
If the job requires rerouting main lines, soldering in tight spaces, or ensuring load-bearing structures for heavy fixtures, you’re better off hiring a pro. A licensed plumber will also ensure permits and inspections are handled properly.
Before you hit buy, double-check the nominal pipe size in inches, the material (brass, copper, PVC, PEX, stainless), the type of connection (threaded, push-fit, compression), and the support spacing recommendations in feet. Confirm any certifications for potable water, and if possible, buy a spare or two of commonly used fittings — they disappear fast once a job starts.
Plumbing fittings and supports may be small pieces of hardware, but they have an outsized impact on how your system performs and lasts. Whether you shop at big-box retailers like Home Depot and Lowe’s, pro distributors like Ferguson and Grainger, or niche online suppliers like SupplyHouse and Build.com, knowing what to buy and how to measure makes all the difference. Match material to application, use the correct support spacing in feet, and don’t skimp on quality for parts that deal with water under pressure. With the right parts and a little patience, most projects go smoothly — and your pipes will thank you.
