Old School O-Rings

The sealing lip of the RST-D is more heavy-duty, so it can cope with pressures of up to 10 bar at slightly lower rotation speeds.

Variety of Oil Seals

EPDM oil seals are less common. They are used in solvent, hot water and steam applications, EPDM resists low temperatures down to -50 °C and UV radiation well. Some types of EPDM are also suitable for higher temperatures up to +150 °C. EPDM oil seals are usually available upon request.

Lubricate the threads of the shaft: The o-ring can easily tear during installation as it consists of threading. But this can be avoided by covering the threads with lubricant or masking tape.
