VPASU | Anti-Siphon Valve Kit

Anti-Siphon Valve Kit

CPS anti-siphon valves are an essential accessory to all Pro-Set vacuum pump models. They prevent the cross-contamination of vacuum pump and compressor oils inside an A/C or refrigeration system, that can cause premature failure. Our three valve sizes fit all CPS and many other vacuum pump models.
