Think of a plumbing hose or supply line as the hidden highway that brings water to faucets, toilets, and appliances. If that highway is narrow, cracked, or full of potholes, everything downstream suffers. Choosing the right material, diameter, and length keeps water flowing smoothly and prevents costly water damage. Plus, the right part can make installation quicker and future repairs easier—so it pays to shop smart.
Walmart is often the first stop for homeowners who want a quick replacement without driving across town. They carry a range of plumbing hoses and supply lines that suit common household needs, from basic rubber hoses to braided alternatives. If you're replacing a worn-out connection to a dishwasher or sink, Walmart's selection can get you back up and running fast.
Two parts commonly found at Walmart include the Hobart Hose Water 3 8 X 12 X 144 00-936801-00002 - Genuine Oem Replacement Part and the Hobart Hose Water Braid Sst 3 4 58 00-749153-00007 - Genuine Oem Replacement Part. These items represent the sort of OEM-grade hoses you can find through national retailers—options that fit industrial-style equipment as well as household fixtures.
Walmart balances price and convenience. Their stores and online marketplace carry both economy and mid-range hoses, and you can often pick up parts the same day. For projects where the design is straightforward—like swapping a 3/8-inch supply line to a faucet—Walmart is a practical choice. Still, if you need specialty fittings or pro-grade braided stainless-steel lines, you might want to compare prices and specs at dedicated pro suppliers.
Home Depot caters to DIYers and professionals alike, making it a strong option when you need more than the basics. You’ll find a wide selection of braided stainless-steel hoses, flexible PVC options, and traditional copper tubing. Home Depot also stocks a broad range of fittings—compression, flare, and NPT—so you can build a complete solution instead of hunting around for compatible parts.
If you’re unsure about sizes or compatibility, Home Depot can help with in-store advice and online guides. Their search filters let you narrow by diameter—like 1/2-inch or 3/8-inch—and by length, so you can quickly land on the correct part for sinks, toilets, or appliance connections.
Lowe’s is another solid retailer for plumbing supply lines, emphasizing brand options and staff support. You’ll find familiar names and a good range of lengths, from short 6-inch connectors to longer 6-foot supply hoses. Lowe’s carries both economy rubber lines and higher-end braided stainless-steel, which resists kinking and is recommended for areas where durability is a must.
Use Lowe’s when you want brand assurance and helpful in-person guidance. If your job requires matching a specific fitting or working around tight spaces under a sink, an associate can point you toward the right diameter—such as 3/8-inch for many sink faucets or 1/2-inch for toilet and valve work.
Ferguson and SupplyHouse are go-to sources when you need contractor-grade supplies. These companies focus on plumbing professionals and serious DIY projects, offering a broader range of materials—braided stainless-steel, EPDM rubber, PEX-compatible hoses, and specialty hoses for appliances and commercial equipment. Their inventories often include longer runs, custom fittings, and higher pressure-rated lines.
If you're renovating a bathroom or replacing multiple fixtures, the bulk availability and variety at Ferguson or SupplyHouse can save time and money. These suppliers often stock ASTM- or NSF-certified products—important if you want guaranteed material standards and longer-term reliability.
Ace Hardware and Menards offer a middle ground: localized advice and a decent parts selection. Ace stores are neighborhood-friendly and can be faster for emergency replacements. Menards has competitive pricing in certain regions and a good variety of supply lines. Amazon brings convenience and an enormous catalog, but beware of mixed-quality third-party listings—always check specs and seller reputation when buying hoses online.
Local stores like Ace can save you a trip by pointing out a simple fix or letting you compare a few options in person. Online stores are best when you need a precise item, like a 3/8-inch to 1/2-inch adapter or a 6-foot braided hose, and you can wait for shipping. Pro suppliers and big-box stores give you the middle ground: selection plus reliable product specs.
Picking the right hose depends on three main things: material, diameter, and length. Material affects durability and flexibility. Braided stainless-steel resist kinks and corrosion, while rubber or PVC can be more affordable and sufficient for lower-pressure, low-exposure situations. Diameter determines flow capacity—1/2-inch will generally provide more flow than 3/8-inch—so match the hose to the fixture’s requirements. Length matters for neat installations; too short and you force connections, too long and you create unnecessary loops that invite wear.
Braided stainless-steel is the premium choice for kitchens and exposed installations. It’s less likely to burst, resists abrasion, and looks tidy under an open sink. Rubber and PVC hoses are fine for hidden connections or temporary fixes but can degrade faster when exposed to heat or chemicals. PEX is great for whole-house lines and offers flexibility and long-term reliability, but PEX-compatible fittings are a must for a secure connection.
Common connector diameters are 3/8-inch and 1/2-inch for sinks and faucets. Toilets often use 3/8-inch with a 1/2-inch shut-off valve depending on the model. Measure twice before buying: determine the distance from the valve to the fixture and add a little slack—an extra 6 to 12 inches is usually enough—so the hose isn't stretched. If you’re replacing an existing line, take the old one with you or photograph fittings to ensure a match.
Even the best hose is only as good as the connection you make. Fittings vary: compression fittings, flare fittings, and National Pipe Thread (NPT) tapered threads are the common types. Compression fittings are standard for supply lines to faucets. Ensure nuts, ferrules, and threads match the hose and valve sizes, and consider using stainless-steel connectors to avoid galvanic corrosion when mixing metals.
Adapters convert between thread types and diameters—for example, converting a 1/2-inch male NPT to a 3/8-inch compression fitting. Keep adapter length and threading in mind to avoid crowding the valve area. If you need an adapter, check thread pitch and type and, when in doubt, bring the fitting to the store for a direct comparison.
Simple mistakes often lead to leaks or premature failures. Don’t overtighten connections—finger-tight plus a half-turn with a wrench is usually enough for compression fittings. Avoid sharp bends and kinks; a kinked hose can fail under pressure. Replace washers and ferrules when you install a new hose, and always test your work at low pressure before you fully restore normal water flow.
For typical supply line swaps, you’ll need an adjustable wrench, a pair of pliers, plumber’s tape for threaded connections, and a bucket to catch drips. A flashlight and small mirror help when working in cramped under-sink spaces. For PEX or copper jobs you may need crimp tools, a tubing cutter, and appropriate fittings.
Quality hoses, proper routing, and good fittings are your best defense. Replace old, perished hoses before they fail—rubber hoses over five years old are often at risk. For exposed or hard-to-reach lines, opt for braided stainless-steel or PEX with secure crimped fittings, and periodically inspect visible connections for corrosion or wet spots.
Before you click “buy” or put an item in your cart, compare these factors: material (stainless vs. rubber), diameter (3/8-inch vs. 1/2-inch), length (add slack), pressure rating, and compatibility with your fixture’s fittings. Also compare warranty and certifications—NSF or UPC-listed parts meet recognized safety standards, and pro suppliers often list performance specifications like maximum pressure and temperature ratings.
If you need speed and affordability, check Walmart or Ace Hardware for common sizes. If you want a balance of pro-grade products and support, Home Depot or Lowe’s are reliable. If you need contractor-grade variety or bulk purchases, look to Ferguson or SupplyHouse. For a massive catalog and potentially niche items, Amazon can be useful—just verify seller ratings and product specs first.
Some jobs are best left to licensed plumbers. If you’re dealing with main water lines, pressurized appliances, gas-related fixtures, or extensive re-piping, professional help will protect your home and ensure local codes are met. For simple supply line swaps and straightforward faucet replacements, many homeowners can handle it themselves with the right parts and a little patience.
Always measure twice and buy once. Keep a small inventory at home—extra 3/8-inch and 1/2-inch braided lines, a couple of shut-off valves, and a few common adapters can save an emergency trip and prevent water damage. Read reviews and product specs, and when in doubt, buy a slightly higher-quality hose; it’s usually worth the small extra cost in longevity and peace of mind.
Choosing the right plumbing hose or supply line comes down to the right material, the correct diameter, and a secure connection. Stores like Walmart, Home Depot, Lowe’s, Ferguson, SupplyHouse, Ace Hardware, Menards, and online marketplaces each offer advantages—whether it’s convenience, selection, pro-grade stock, or price. Measure accurately, know your fittings, and don’t be afraid to ask for help when a job feels beyond your DIY comfort zone. With the right part in hand, a few basic tools, and a careful approach, most homeowners can complete common supply line projects safely and effectively.
