Brannan P.B.GLO.100 Series Gauges are the highest quality liquid filled gauges available to us. The heavy one-piece die casting integrates the case, connection, movement support and bourdon tube support into a solid gasket ring that eliminates leakage and when coupled with the glycerin fill, greatly reduces the effects of vibration, pulsation and shock. 

The lenses are moulded plexiglass and are sealed with an o-ring. The lenses are protected with a stainless steel ring.

This type of liquid filled pressure gauges are used for a variety of applications that are not corrosive to brass.
