- For Old 407 and 408 Style Vacuum Cups
This CRL Vac Cup Replacement Rubber Pad fits CRL Old Style 407 Single Vacuum Cups. The trigger, pin, spring and plate are interchangeable in either model but the replacement pads must be ordered to fit your specific model. If you have the double cup, be sure to order two of each part. We always recommend using GL22 Glycerine to condition any vacuum cup rubber to keep them soft and pliable for maximum effectiveness and safety.
