Model Rubber Sealing Material
CK3R Fluorine Rubber (FPM)
— TMO 150 °C (302 °F)
Special use As a vacuum breaker*
*CK3R, CKF3R and CKF3RG (with rubber sealing) should not be used.
Due to the nature of the rubber, there is a possibility of the disc sticking to the metal valve seat,
compromising product performance at the very low differential pressures under which vacuum
breakers operate.
