UPU

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
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
