PTFE Filled Polymer Step Seal Ring

PTFE filled polymer Step Seal ring

The piston rod seal must meet no dynamic leakage to the atmosphere under all working conditions, 

and must be a perfect static seal when the machine is stopped. Through the introduction of the Step 

seal ring, we can use the structure of multiple rod seals. The Stellar seal system can maintain a good 

sealing effect in both static and dynamic conditions.

Secondly, the hydraulic system, reciprocating motion, and heavy-duty two-way piston sealing under 

high pressure and low pressure and high frequency conditions are very good, all of which stem 

from the existence of the Stem seal ring. Its advantageous characteristics have good dynamic and 

static sealing performance, suitable for long or short stroke working conditions, and suitable for 

large piston clearance in a wide range of fluid and high temperature places.

Kaflon was set up in 2014 and covers an area of 1,500 square meters and construction area of 1,500 

square meters with 22 Technician and engineer.
