This compression nut secures 3/8 in. refrigeration or water tubing to a matching compression fitting, creating a tight mechanical seal for supply lines. It's a simple, serviceable fastener used on valves and pipe connections. What it does:
- Threads onto a compression fitting to hold ferrule and tubing in place
- Helps create a leak-resistant joint on 3/8 in. tubing connections
- Commonly used on water supply, ice maker, or refrigeration line fittings
- Replaces a worn or damaged nut that causes loose or leaking connections
What's included: One compression nut for 3/8 in. tubing. Install notes:
- Turn off water or power to the appliance and relieve system pressure before servicing
- Hand-start threads to avoid cross-threading; tighten snugly with appropriate wrenches
- Inspect ferrule and tubing; replace ferrule or cut tubing square if reusing connection
- If you see persistent leaks after tightening, stop and check components.
