Abstract

Piston rod seal for shock absorbers comprises on the friction surfaces a friction reducing lubricating material. Specif., the friction surface is a pressure disc whose lubricant coating is of P.T.F.E., or a fluoro elastomer e.g., a linear copolymer of vinylidene fluoride and hexafluoropropylene with a mol. wt. of 60,000 and a fluorine content of 65%.
