Do not include the homogeneous ring in calculating pressure rating. Due to the different material, it is difficult to rate this type of ring. If you wish to use all homogeneous rings, tests should be conducted to verify design stability.

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 -
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. -
Style PU seals are molded from high quality urethane and designed specifically for piston applications. -

The Z-Seal is a squeeze type seal, combining the excellent sealability and low compression set of a resilient rubber lip with the greater anti-extrusion characteristics of a hard thermoplastic base. Under low pressure conditions, the sealing lip provides its own compressive seal force. As pressure increases, hydrostatic pressure is mechanically transmitted through the elastomeric seal element into the anti-extrusion base. The applied force then deflects radially in a controlled manner, closing the extrusion gap behind the sealing lip. Under this condition, maximum sealing effectiveness is achieved.SEAL INFORMATION MATERIAL 95A URETHANE
