Spend More Time Calibrating and Less Time Looking for Leaks

These adapters use a pressure assisted seal which means the more pressure that is applied, the better the seal. Connect to pressure gauges which have male NPT, BSPP or Metric threads - without using a wrench or thread sealant. Quickly switch between gauges while calibrating or testing without worrying about leaks!
