Symmetrical seals 

---

Symmetrical seals are seals whose cross section, when viewed from a cut away, is symmetrical or the same on each side of the center line.

The symmetrical design allows for interchangeability between rod and piston applications. This permits direct substitution in the same grooves when unexpected problems arise. For More information and to check availability, click on the seal profile.

ROD SEALS:

---

All AHP Seals Rod seals are Non-symmetrical.

Non-symmetrical rod seals are seals whose cross section when viewed from a cut away is not symmetrical or the same on each side of the center line.

A Non-Symmetrical rod seal can only be used as a rod seal and not as a piston seal. For more information and to check availability, click on the seal profile.

PISTON SEALS:

---

All AHP Seals Piston seals are Non-symmetrical

Non-symmetrical piston seals are seals who’s cross section, when viewed from a cut away, is not symmetrical or the same on each side of the center line.   A Non-Symmetrical piston seal can only be used as a piston seal and not as a rod seal.

WIPERS, EXCLUDERS:

---

The function of a wiper is to prevent dirt from penetrating the system, cylinders valves, etc. The wiper has a wiping lip to scrape off the rod contaminants. For more information and to check availability, click on the seal profile.

WEAR RINGS, (Wear Bands, Guide Rings):

---

The sliding movements, i.e. a piston in a tube, risk metal to metal contact that will damage the surface and the seals. Therefore, piston and rod need to be supported by precision guiding elements such as wear rings, wear bands or guide rings.

BACK UP RINGS, WASHERS:

---

Back-up rings are mounted on the non-pressure side of O-Rings or seals to help them withstand high pressure without extruding and getting damaged.

STATIC SEALS:

---

When there is no motion of the mating assembly parts upon the seal, a static condition exists. A Static seal is a seal to prevent the loss of a fluid or gas.
