Ideal uses and scenarios
These connections are perfect for under-sink repairs, retrofit projects, and new installations where a 1/2" supply line must feed a 3/8" fixture line—such as faucet supply hookups or appliance water lines. The straight design helps maintain proper alignment, reducing strain on tubing and minimizing potential leaks over time.
- Replace worn or corroded compression fittings on copper supply lines
- Connect a 1/2" shutoff valve to a 3/8" faucet or appliance line
- Use in retrofit projects where soldering isn’t practical or feasible
Installation tips
- Shut off the water supply and relieve any built-up pressure.
- Slide the compression nut and ferrule onto the supply line, then insert the tubing into the connector end until fully seated.
- Hand-tighten the nut, then give a final snug turn with a wrench to secure the seal.
- Restore water supply and inspect for leaks; tighten slightly if necessary.
