For linear and reciprocating dynamic sealing applications

AHP Seals' non-symmetric Piston Seal designs ensure a high static seal force on the inside diameter of the seal, which adds stability and helps to limit the rocking motion of the seal as the piston cycles, and in turn, can reduce fluid seepage.

 

We offer these types of piston seals:

• Single-acting (unidirectional)
  
• Double-acting (bidirectional)

Piston Seal Profiles

Single-acting (unidirectional): Sealing pressure only from one side (most common)

 

K01	K01A	K01B	K02	K02A	K03
K04	K05	K16	K19	K82

 

Double-acting (bidirectional): Capable of sealing pressure from both sides.

 

K08	K08C	K08D	K81	K08E	K20
K08F	P56	P57	P50	P51	P52
P53	P54	P55	K35
