We are a professional factory engaging in producing shock absorber pistons, with many 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.


Here is the physical property of PTFE rings:


Tensile strength       ≥23N/mm2


Carrying capacity    ≥15N/mm3


Working temperature    -80°C to 260°C


Friction coefficient (dry)       ≤0.16




1. Wide temperature range/high temperature resistance


2. Standard material according to technical drawing


3. OEM quality standard guarantee


4. Sample purpose order accepted


5. Complex multi-level design


6. Reduces friction and ensure smooth rod reaction
