POLINI EVO, PTFE, 19x32x7 /
22,7x47x7x7 mm, blue
POLINI's PTFE coated engine oil seal set : Oil seals produced including PTFE coating can withstand higher temperatures and are also more fuel and oil resistant than oil seals made using rubber based materials. Their main body is constructed using a Fluoro Polymer Material (FPM) with a steel frame for added stability. The shaft contact area is coated with PTFE.
They are also available for use with small-frame motor crankshafts with an oil seal seating area diameter of either 19 or 20mm.
Conclusion : The FPM constructed, PTFE coated POLINI engine oil seals are just as well suited to standard motor set ups as they are to the more performance orientated motor tuning projects.
