Check Valve Assembly #11630D

Old Part Numbers: 5140030-78, CAC3812-SU3-T-3719

Air compressor check valve assembly. If your unit has a hard time restarting when trying to cycle, order this.

If your pressure switch is leaking out of the small bleeder valve on the side (or located underneath) after the unit shuts off, order a tank check valve instead, your pressure switch is OK.
