1st Rod Seal | PTFE - Low friction and long service life; Protects secondary seal from pressure spikes; Allows a fine film of oil to pass ensuring the necessary lubrication of the secondary seal; Geometry designed to vent pressure from the reverse side - to reduce possibility of pressure trap between seals; Acts as an internal wiper to protect secondary seal from internal contaminants
2nd Rod Seal | PTFE - Low friction; Excellent low-pressure seal ability, long service life
Bronze Teflon Wiper | Double-acting wiper ensures the best sealing performance
Metallic Rod Scraper | (Standard) Rugged scraper deflects contamination away from the rod seals for long service life
Piston Rod | Steel SAE 1045 Ground, hard chrome-plated & polished 17 - 4 PH; stainless steel available as an option
Gland Retainer
Gland Bushing | Cartridge-type AL - bronze
Check Valve & Cushion Valve | Fully retained for safety
