The Wilkins REMXLCR and REMXLPFR retrofit tailpieces are easy to install and can replace any brand without the need for additional fittings or components. The REMXLCR is a sweat connection tailpiece option. This copper retrofit tailpiece slides over existing copper tubing and is soldered in place without additional couplings or adaptors. In tight spaces, the copper tailpiece can be cut to length. The REMXLPFR is a solder-free push-fit connection tailpiece. This retrofit option allows for quick push-on installation into an existing regulator footprint without the need for solder, torch, flux and more.
