Product Description

PTFE Material

PTFE is a very useful material because it has a unique combination of properties. PTFE is chemically inert, weatherable, excellent electrical insulation, high temperature resistance, a low coefficient of friction and non-adhesive properties. Shrinkable tubing is also used as roll covers and to protect electrical parts or components. PTFE can also be skived or extruded into tapes and films that can be used for seals and gasket materials. 

PTFE Piston seals

Piston seals maintain sealing contact between the piston and the cylinder bore. Differential pressures acting on the piston to extend or retract the piston rod can be in excess of 400 bar (5 800 psi). The pressure acting on the piston seal increases contact forces between the piston seal and cylinder surface. Therefore, the surface properties of the sealing surfaces are critical to proper seal performance

Hydraulic seals Ptfe piston seals -Glyd rings (GSF)


PTFE Compressor Slide Glyd Ring Style Piston Seal GSF have designs in 2 parts consisting of special compound PTFE ring and O-ring used as pressure ring. This design is suitable up to a pressure of 60 MPa in double acting cylinders

Lip type shaft oil seals are widely used in rotary screw airends and come in a variety of designs and materials. This seal functions to retain the oil inside the airend, but also to keep air, dust and dirt from sucking in along the rotating shaft when the machine is off load. (When the inlet valve closes, if the airend continues to rotate, a vacuum may be pulled on the inlet end.)

PTFE Rod seals


Step Seal provides exceptional reliability for non-critical sealing applications. Restricts oil flow by eliminating straight path of leakage. And is usually made from synthetic rubber qualitative protection ring and filled ptfe qualitative special shape of rectangular, trapezoidal seal ring,

PTFE shaft seals - Spring Energized Seals

Spring Energized Seals made with PTFE seals offer extreme-temperature, high-pressure, chemically inert, static and dynamic seals for the most demanding applications. The flexible PTFE sealing jacket, made resilient by an internal energizing spring, applies a load to the sealing element at low pressures.
