UKP u-seals are designed to act as a positive sealing, low friction replacement for conventional rubber u-seals. Molded from polyurethane, UKP u-seals provide long life and high resistance against extrusion. Low friction allows these seals to run smoothly in lubricated or non-lubricated cylinder. Available for bore sealing, the flexible dynamic lip provides very low breakaway friction and steady motion. -
UKR u-seals are designed to act as a positive sealing, low friction replacement for conventional rubber u-seals. Molded from polyurethane, UKR u-seals provide long life and high resistance against extrusion. Low friction allows these seals to run smoothly in lubricated or non-lucricated cylinder. Available for rod sealing, the flexible dynamic lip provides very low breakaway friction and steady motion. -
Style UPU Premium U-Seals are molded from ultra tough urethane for severe service conditions. They feature higher tensile strength and modulus for extrusion resistance. These seals are used in high energy services such as rock drills and shock absorbing devices where high internal heat is generated.SEAL INFORMATION MATERIAL 93A URETHANE TEMPERATURE RANGE -65° to +300° F PRESSURE RANGE 0 to 5,000 PSI SPEED 3 FT/SEC PART NUMBER (Prefix)(CS) - (Inside Dia) - (Height) 
Standard - Height and cross section are equal, thus giving a square seal. Utilizes type 'D' lip. Typical Part Number UPU25-2.50 
Deep - Utilizes the same 'D' lip, but the seal height is greater than the cross section, thus giving a rectangular shape. Typical Part Number UPU25-2.50-37D 
Type SQB - Same dimensions as the Standard seal. Beveled lip design provides better film breaking. Utilizes type 'B' lip. Typical Part Number UPU25-2.50-SQB 
Type B - Same dimensions as the Deep seal. Beveled lip design provides better film breaking. Utilizes type 'B' lip. Typical Part Number UPU25-2.50-37B -

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
