Rod Seals

For linear and reciprocating dynamic sealing applications

hyrdraulic seals

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:

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
