Product Details

Flared PTFE plus filler Banded Piston With tensile strength 18.5MPa Used In Car Shocks



Based on powder metallurgy piston, banded with advanced PTFE layer with the advantage of good
wear-resistance, low friction and high temperature resistance.

Products have passed the test center of Shanghai Plastics Research Institute. Annual capacity can reach


20,000,000pcs. We will add new equipment to enlarge our capacity. We’ve set up good relationship with


big factories at home and abroad.

XIAYI is a professional factory engaging in producing shock absorber pistons, with more than six years


experiences in this line.


As we know, shock absorbers play a large part in the performance of the vehicle and are therefore


advised for a routine check up at regular intervals.


We can offer you the pistons with good quality and fit for the different road condition. We choose


advanced material and this provides long seal life, contributing to shock absorbers that can meet the


demands from car manufacturers of one hundred thousand kilometers before replacement.
