Product Description

Product Description

The Spring Energized PTFE filled with carbon seal is a spring- energized, pressure-assisted sealing device consisting of a PTFE filled with carbon partially encapsulating a corrosion-resistant V shape metal spring energizer.

Carbon fiber is a category of composite materials derived from carbon - based sources, renowned for their exceptional strength, lightweight nature, and versatility across various industries and applications.

PTFE filled with carbon material has exceptional strength and lightweight nature,electrical conductivity and thermal stability,chemical resistance.Due to their ability to enhance strength, conductivity, and performance in diverse applications.

Wiper Seal

 

Rotary  Seal   For additional models and sizes, please contact us.
Basic Functions of Rotary Shaft Seals:Retain lubricants within the system.Exclude contaminants from entering the system.Protect lubricated bearings.Withstand pressure differentials in certain applications.

Piston Seal 
For additional models and sizes, please contact us.

Piston seals are used to create a sealed contact between

 
the piston and cylinder. The moving piston generates high 
 
pressure on the seal, increasing the contact force

between the seal and the cylinder surface. Therefore, the

surface characteristics of the dynamic sealing interface

 are crucial for sealing performance.
 
 
 

Piston Rod Seal  

For additional models and sizes, please contact us.

Piston rod seals and buffer seals are designed to seal the

sliding motion between the hydraulic cylinder and the 

piston rod. Depending on the application, the sealing

system may consist of both a piston rod seal and a buffer

seal (commonly used in heavy-duty equipment) or only a

piston rod seal.In addition to their sealing function, these 
 
components provide a thin lubricating film on the piston

rod, which lubricates the rod itself and the 
 
wiper seal.
