Suction Pad-22mm (U.54AV1) - for use with USAG 439P, Facom U.54A, Beta 1455SVP and Goodson AVLP-300 air operated valve grinders. Facom has discontinued selling all of the suction pads and I'll be stocking the identical pad purchased through USAG (a Facom company).
USAG/Facom U.54A1 is the model number for a replacement 22 mm suction cup (pad) designed for the Facom U.54A Pneumatic/Air-Operated Valve Grinder. The parent tool (Facom U.54A) is a professional pneumatic tool used by automotive technicians to automate the time-consuming process of lapping engine valves into cylinder head valve seats.
The U.54A1 (22 mm) pad is the smallest standard size available for this tool. It grips smaller automotive engine valves securely using the tool's directional oscillation and 8-bar operating pressure to create a perfect, leak-free mechanical seal.
