SFS SPLIT FLANGE SEALS
FOR 4-BOLT SPLIT FLANGE CONNECTORS
Flange seals are a one piece dual durometer urethane static seal. The black outer part is a tough, extrusion resistant 95 Durometer and the yellow inner layer is 57 Durometer that has low compression set and excellent sealing properties. These seals are a direct replacement for o-rings and do not require modification to any split flange groove.SEAL INFORMATION MATERIAL URETHANE TEMPERATURE RANGE -40° TO +200°F PRESSURE RANGE 0 TO 3000 PSI SPEED STATIC PART NUMBER (Prefix) - (Dash No.) -
QR, BUNA-N QUAD RINGS
The four-lobed design of these seals provides twice the sealing surface of ordinary o-rings. They can be used in a variety of static and dynamic sealing applications including rotary, reciprocating or oscillating motion.
NOTE: Last three digits of part number corresponds to standard o-ring dash numbers (568-218 = QR-4218)
