Parker’s AH profile, premium double-lip canned wiper is used in heavy-duty hydraulics. Its polyurethane and metal can construction facilitates press-fit installation to guard against O.D. contamination and results in simple counter-bore groove machining. The wiping lip on the AH profile wiper is very aggressive, eliminating the ingression of dust, mud and moisture from harsh work areas. The AH Profile wiper is ideal for the most demanding heavy-duty cylinder applications. The aggressive wiping lip on the AH profile that faces the environment ensures the utmost performance in contaminant exclusion along the rod. When used in high pressure applications with the proper Parker rod seals, the AH profile provides redundant sealing for leakage reduction.

NOTE: When using the AH 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.
