B38;K Llc 6630-003 Push on Coupling 1/2 in Copper Cpvc Pex

Product Description

The B38;K LLC 6630-003 is a 1/2-inch by 1/2-inch push-on coupling with stop, designed for heat-free joining of copper, CPVC, and PEX tubing. It uses a push-to-connect mechanism that eliminates the need for soldering, crimping tools, or open flame at the joint. This fitting is removable and reusable, making it well-suited for tight spaces, repair work, or installations where future access is likely. Lead content on wetted surfaces is less than 0.025 percent weighted average, meeting California and Vermont low-lead compliance standards. Plumbers and pipefitters working on residential or light commercial water systems are the primary installers of this fitting type.

This coupling is used in residential and light commercial plumbing systems where copper, CPVC, or PEX tubing of 1/2-inch nominal size is present. It is a practical choice for repair scenarios, new rough-in work, and retrofit applications where a flame-free joining method is required or preferred. The reusable design allows technicians to disconnect and reposition the fitting during installation without damaging the tubing or the fitting itself, reducing material waste on multi-stage projects.

Key Features

• Heat-free push-on connection — no soldering, torch, or crimping tool required
• Removable and reusable fitting system for maximum installation flexibility
• Compatible with copper, CPVC, and PEX tubing in 1/2-inch nominal size
• Less than 0.025 percent weighted average lead content on wetted surfaces
• California and Vermont low-lead compliant
• Built-in stop ensures consistent insertion depth on every connection

Compatibility

Designed for use with 1/2-inch copper, CPVC, and PEX tubing in residential and light commercial plumbing applications. Verify tubing outside diameter meets push-fit fitting tolerances before installation.

Installation Notes

Installation is performed by licensed plumbers following applicable IPC or local plumbing code requirements. Shut off the water supply and depressurize the line before making or breaking any connection. Ensure tubing ends are cut square, deburred, and clean before insertion into the fitting. To disconnect, use the manufacturer-specified removal tool or collar — do not pull on the tubing without releasing the retaining mechanism.
