Supply Lines

Supply lines keep water moving reliably from your home’s plumbing to fixtures and appliances. You’ll find faucet supply lines, toilet supply lines, dishwasher and ice maker hoses, and water heater connectors designed for fast, leak-free installation. Choose from braided stainless steel for maximum burst strength, flexible polymer and PVC for budget-friendly projects, or rigid copper risers for a clean, traditional look. Options include 3/8-in and 1/2-in compression, 3/4-in hose thread, and FIP/MIP connections, plus push-to-connect ends that speed up repairs without special tools.

The right plumbing supply line improves flow, resists corrosion, and handles temperature and pressure swings. Look for lead-free, code-compliant products with NSF/UPC listings, robust crimp collars, and premium EPDM gaskets. Common lengths range from 6 to 60 inches to route around obstacles without kinks. For water heaters, corrugated stainless connectors absorb vibration and thermal expansion; for toilets and faucets, braided lines tuck neatly inside cabinets.

Installation is straightforward: measure twice, avoid sharp bends, and tighten compression nuts hand-tight plus a quarter turn. Use thread seal tape only on tapered pipe threads, not on compression or gasketed fittings. Always open the stop valve slowly and check for seepage with a dry tissue.

Helpful picks and tips:
- Keep spare faucet and toilet supply lines on hand for quick fixes.
- Replace aging gray PVC or rubber lines; upgrade to braided stainless for peace of mind.
- Match connection types at both ends to avoid adapters that add leak points.
- Inspect annually for rust, bulges, or stiffness and renew every 5–10 years.
