B38;K Llc 6630-004 Push on Coupling 3/4 in Copper Cpvc Pex

Product Description

The B38;K LLC 6630-004 is a 3/4-inch by 3/4-inch push-on coupling with stop, designed for joining copper, CPVC, and PEX tubing without heat, solder, or open flame. The fitting uses a tool-free push-to-connect mechanism, making it a fast and reliable choice for plumbing repairs, remodels, and new installations. It is removable and reusable, providing flexibility when layouts change or adjustments are needed on the job. The wetted surfaces contain less than 0.025 percent weighted average lead content, meeting California and Vermont low-lead compliance standards. Plumbers and pipefitters working on potable water systems will find this fitting well-suited to both residential and light commercial applications.

This coupling is intended for use in water supply systems where copper, CPVC, or PEX tubing is present. The push-on, heat-free design makes it practical in tight spaces, near combustibles, or wherever torch work is restricted or impractical. The 3/4-inch by 3/4-inch configuration suits common residential supply line sizing. Its reusable nature makes it a useful fitting to keep on the truck for emergency repairs or temporary connections.
