Description
The LH-Type Wiper Seal (Light Heavy-duty wiper) is a versatile, double-lip scraping element designed for hydraulic and pneumatic cylinders operating in moderately contaminated environments. Engineered to balance effective contaminant exclusion with low friction operation, the LH-Type provides reliable rod protection for applications where conditions are challenging but not severe enough to require an aggressive heavy-duty scraper.

Cracking, chunking, or deformation of either lip
Contamination found behind the wiper (in the gland area)
