Meet the SharkBite 1/4 in. PTC x 3/8 in. Compression Brass Stop Valve Connector—a compact, dependable shut-off valve designed for quick, tool-free installs in tight spaces. This connector blends a push-to-connect (PTC) 1/4 in. end with a 3/8 in. compression end, delivering a reliable seal with minimal effort.
One end accepts 1/4 in. tubing with SharkBite’s proven push-to-connect technology—just insert and push to lock. The opposite end uses a standard 3/8 in. compression connection, allowing you to pair with existing tubing and fittings without soldering or crimping. Built from lead-free brass, this stop valve connector is designed for durability in everyday water supply applications.

Ideal uses and practical scenarios
- Install a quick shut-off for a faucet, ice maker, dishwasher, or other fixtures without soldering or tools on the PTC side.
- Create a temporary or permanent shut-off in tight spaces where traditional valves don’t fit, thanks to its compact brass body.
- Retrofit projects that require converting an existing 3/8 in. compression line to a push-to-connect branch for easier serviceability.
Installation tips
- For the 1/4 in. PTC end, ensure the tubing is clean and cut square, then push firmly until it seats completely.
- On the 3/8 in. compression side, slide the compression nut and ferrule onto the tubing, insert into the connector, and tighten the nut with a wrench until snug.
- After installation, check for leaks and reseat or tighten as needed. Avoid overtightening the compression side to prevent damage.
