Seal Elastomer Data

Seal Elastomer	Operation Temperature（°C）	Operation Temperature（°F）
EPDM-P	-40°C ～ +150°C	-40°F ～ +302°F

Physical characteristics

*Defined per OCP specifications, Rated Flow is the reference flow rate used to measure pressure drop and determine the published Cv (flow coefficient).

Performance Parameters

Force to Connect vs Pressure：Changes in connection force for different sizes when pressure increases (compressed air).

Flow Data：Flow rate vs. pressure drop (test fluid: 60°F water).

5 m/s Industry reference

A reference ow rate corresponding to 5 m/s is widely adopted in
industry to balance pressure drop and ow stability.
