The BRASSCRAFT PFER12 is a compression sleeve designed for use with 1/2-inch OD plastic tubing. Also referred to as a ferrule, this fitting component seats against the compression nut and body to create a leak-free mechanical seal when the nut is tightened. It is a standard component in compression-style plumbing connections and is installed by licensed plumbers and experienced trades during supply line and fixture connection work.
This sleeve is sized specifically for 1/2-inch OD plastic tubing, making it appropriate for residential and light commercial plumbing applications where compression fittings are used to connect supply lines, shut-off valves, or similar plumbing fixtures. It is a direct replacement or supplemental component for compression assemblies that use plastic tubing.
Designed as an OEM-style replacement compression sleeve for use with 1/2-inch OD plastic tubing in standard compression fitting assemblies.
Installation is performed by a licensed plumber or qualified trades professional. Shut off the water supply and relieve line pressure before disassembling any compression fitting. Slide the ferrule onto the tubing before threading the compression nut, and ensure the sleeve is seated squarely against the fitting body prior to tightening. Do not over-tighten compression nuts, as this can deform the sleeve and compromise the seal.
