Heavy-Duty Seals: Utilizes a multi-lip seal configuration, including primary pressure seals, secondary buffer seals, and wear bands (guide rings). This system is designed to contain high pressure, exclude external contaminants, and ensure long service life.
Wiper Seal: A critical component that scrapes dirt, mud, and debris off the rod as it retracts into the barrel, protecting the internal seals from abrasive contamination—the number one cause of cylinder failure.
