For linear and reciprocating dynamic sealing applications

The Rod Seal is typically the most critical seal on any type of equipment because a leak in a rod seal can not only decrease the efficiency of the equipment, it also can potentially cause environmental issues. Particular attention should be paid to selecting the best rod seal for your application. AHP Seals utilizes a nonsymmetrical design in which the diameter of the seal is oversized for the groove diameter. Oversizing creates a hoop pressure resulting in higher static sealing force on the seal in the gland, which aids in stability and helps to limit the rocking motion of the seal as the rod cycles, which in turn can reduce fluid seepage.

 

We offer two types of rod seals:

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

Rod Seal Profiles

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

 

S1	S01A	S01B	S02	S02A	S03
S04	S05	S08	S16	S17	S17A
S17B	S17C	S17D	S19	R50	R51
R52	R53	S19B

 

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

 

S20	R56	R54	R55
