Shut-Off Valves

Shut-Off Valves give you fast, reliable control over water lines, helping prevent water damage, simplify fixture swaps, and make repairs safer. This collection covers residential and commercial plumbing needs, from main water shut-off valves to compact fixture supply stops for sinks, toilets, and appliances.

Choose the right style for your job. Quarter-turn ball shut-off valves offer smooth operation and long service life, while angle stop and straight stop valves fit tight spaces at the point of use. Look for full-port designs to maintain flow, dual-outlet stops for combined faucet and dishwasher lines, and frost-proof stop-and-waste valves for outdoor spigots.

Materials and compliance matter. Lead-free brass and stainless-steel bodies resist corrosion and meet potable water standards such as NSF/ANSI 61 and 372. Common sizes range from 1/4 in. to 2 in., with pressure and temperature ratings listed by each model.

Match the connection to your pipe:
- Compression and sweat (solder) for copper.
- Push-to-connect for no-solder installs on copper, PEX, or CPVC.
- Threaded NPT for galvanized or transitions.
- PEX crimp/expand options for dedicated PEX runs.

Installation is straightforward:
- Shut water, drain lines, and cut square with a tubing cutter.
- Deburr ends; use PTFE tape or pipe sealant on threaded connections.
- Orient the handle for access, secure the valve, restore water, and check for leaks.

Maintenance tips:
- Exercise shut-off valves twice a year to prevent sticking.
- Tighten packing nuts slightly to stop stem seepage or replace packing, stems, and handles with valve repair kits.
- Replace aging or seized units; signs include corrosion, stiff operation, and drips.
