Parker’s AY profile, premium double-lip wiper is used in light to heavy-duty hydraulics. When used in high pressure applications with the proper Parker rod seals, the AY profile complements the sealing system by providing an additional beveled sealing lip, yielding excellent film-breaking and the driest rod sealing available. These dual acting features along with its space-saving single-gland configuration, enable it to be used by itself in low pressure applications as both the rod seal and the wiper. Knife-trimmed sealing lips ensure the best possible film breaking.

NOTE: When using the AY wiper in conjunction with other rod seals, it is important to select a rod seal profile that enables pressure relief of fluid into the system, otherwise a pressure trap may form between the wiper and rod seal. Suggested rod profiles are Parker’s BT Profile, BS Profile, and B3 Profile U-cup seals.
