Supply Line Accessories keep water flowing safely from shut-off valves to fixtures and appliances. Whether you’re installing a faucet, toilet, dishwasher, ice maker, washing machine, or water heater, the right connectors and parts deliver leak-free, code-compliant performance and faster installs.

This category includes braided stainless steel and reinforced polymer connectors, copper flex lines, compression fittings, adapters, angle stops (straight and angle, quarter‑turn and multi‑turn), escutcheons, gaskets, O‑rings, ferrules, bushings, couplings, dielectric nipples, and thread sealants (PTFE tape and pipe dope). Look for lead‑free brass components with corrosion resistance and certifications such as UPC and NSF/ANSI 61/372. Common sizes are easy to match: 3/8 in OD compression for faucets, 7/8 in ballcock for toilets, 1/4 in OD for ice makers, 3/4 in hose thread for washing machines, and 3/4 in FIP for many water heater connections. Options are available for copper, PEX, CPVC, and galvanized systems.

Choosing the right supply line accessory saves time and prevents callbacks. Select the correct length with a gentle loop to avoid kinks, and verify temperature and pressure ratings for the application. For quick serviceability, use quarter‑turn shut‑off valves. For washing machines, choose burst‑proof, braided hoses with crimped fittings. For PEX, use the proper insert and support sleeves as specified by the fitting manufacturer.

Installation is straightforward: shut off water and relieve pressure; apply thread sealant only to tapered NPT threads—never to compression threads; hand‑tighten, then snug by a quarter‑turn; support tubing and avoid sharp bends; pressurize and check for leaks. Recheck after 24 hours. Maintenance is simple too—inspect annually, replace aging rubber washers and O‑rings, and upgrade older rubber hoses to braided stainless assemblies. For water heaters, use dielectric connections to help reduce galvanic corrosion at dissimilar metals.

Shop Supply Line Accessories to achieve reliable connections, clean finishes at the wall, and smooth service shutoffs—key advantages for both DIY repairs and professional plumbing projects.
