Sharkbite/cash Acme U4016LFA Pb Conversion Coupling 3/4 in

Product Description

The SHARKBITE/CASH ACME U4016LFA is a lead-free polybutylene conversion coupling designed to transition from existing polybutylene pipe to standard plumbing systems using a push-to-connect fitting. Sized at 3/4 inches x 3/4 inches, it connects to ASTM D3309 specification polybutylene pipe on one end and accepts a standard SharkBite push-fit connection on the other. The fitting is lead-free compliant under Federal Law 111-380, making it suitable for potable water applications. Licensed plumbers and remodeling contractors use this fitting when repairing or replacing sections of polybutylene supply lines without soldering or crimping tools.

This coupling is intended for residential potable water supply systems that originally used polybutylene pipe, a material widely installed from the late 1970s through the mid-1990s. It is specifically engineered to work with ASTM D3309 compliant polybutylene pipe in 3/4 inches diameter. The push-to-connect design allows for fast field repairs on cold or hot water supply lines. It is sold in a package quantity of 6 units and arrives bagged for jobsite convenience.

Installation Notes

Installation should be performed by a licensed plumber familiar with polybutylene pipe repair procedures. Shut off the water supply and relieve system pressure before cutting into any existing line. Inspect the polybutylene pipe end carefully — the pipe must be in sound condition with a clean, square cut; do not install this fitting onto pipe that shows cracking, discoloration, or surface decay. Local plumbing codes (IPC and applicable state amendments) govern the use of push-to-connect fittings in concealed or permanent installations.
