These lip-type buffer seals are designed for replacement in Caterpillar® cylinders. The hinged-lip design reduces friction, heat, and wear under low-pressure conditions and acts as a check valve allowing back-pressure relief. Seals for rod sizes 2-1/8" and under do not have a back-up ring. Caterpillar Specific Buffer Seals - DYR Style -
Molded of 90A Durometer Buna-N Rubber, these 'Parback®' Style Dished Cross Section back-up rings provide excellent extrusion resistance. Stretched for installation, they return quickly to their original size for easy installation.

Our vee sets are the finest quality available in the industry. While all sets incorporate fabric reinforced rubber pressure rings, one or two urethane rings are included to improve low pressure sealing, when it is feasible. Most sets use nylon adaptors. Properly installed the pressure limits are as follows: 3,000 PSI = 4 VEES 5,000 PSI = 5 VEES 10,000 PSI = 6 VEES CONSTRUCTION CODE Example: FA-2U-3F-MA FA - 1 TOP ADAPTOR 2U - 2 URETHANE VEE RINGS 2F - 2 FABRIC VEE RINGS MA - 1 BOTTOM ADAPTOR V= FLUOROCARBON U= SPECIAL URETHANE VEE H= HYTREL W= WIPER INCLUDEDSEAL INFORMATION MATERIAL FABRIC REINFORCED RUBBER
