Swagelok^® Pressure Gauges, Ultrahigh-Purity and Clean Dry Air (PGU and PGC Series)

Swagelok^® ultrahigh-purity and clean dry air pressure gauges use a Bourdon tube to reliably monitor positive system pressure and vacuum.

Request Pressure Gauge Information

Swagelok^® PGU series ultrahigh-purity pressure gauges and Swagelok^® PGC series clean dry air pressure gauges are designed for use in a wide range of applications, from bulk gas distribution to process tool applications. Their accuracy is in accordance with ASME B40.1, EN837-1, and JIS B7505.

PGU series gauges are ultrahigh-purity (UHP) “clean” for semiconductor gas applications in accordance with SEMI/SEMATECH, are cleaned and packaged in a class 100/10 cleanroom, and have 316L VAR end connections. PGC series gauges are assembled, cleaned, and packaged in a class 100 cleanroom and have 1/4 in. NPT end connections. Both series are purged with nitrogen and include protective cap over threaded connection. Every ultrahigh-purity and clean dry air gauge is 100% factory calibrated and helium leak tested to a maximum rate of 1× 10-9 std cm³/s.
