DGX Premium Dual SPG in PSI and BAR

This DGX Dual gauge displays imperial and metric units simultaneously. It displays PSI in a white halo around the black center portion that display the BAR readings. Designed for high visibility in low light and no light conditions, the needle and ALL white markings are luminescent glow-in-the-dark. We have also limited the number of "tick" markings on the dial to make for a clean and easy-to-read face. The SPG's are otherwise identical to our white face and black face SPGs, manufactured by Termo with a chrome plated all brass housing with a tempered mineral glass face cover and a beryllium copper Bourdon tube mechanism incorporating a rack and pinion movement. Our naked SPGs include the spool, with two oxygen compatible o-rings, to mate the HP hose swivel to the gauge. All these pressure gauges are Nitrox Ready and include an over pressure relief plug.

• Chrome-plated all brass housing
• Tempered mineral glass face cover
• Bourdon tube mechanism with rack and pinion movement
• Medium { 2 in | 5 cm } diameter with { 1.75 in | 4.5 cm } face and { 1 in | 2.5 cm } thickness
• Includes both PSI and Bar graduations, on a white and black face
• Includes air spool required for assembly to a hose

All high pressure hoses and SPGs use an 'air spool' with two tiny o-rings to mate the swivel connector on the hose to the fitting on the gauge. With a worn or missing air spool, any HP hose will LEAK at the swivel. The air spool is INCLUDED with this gauge and we strongly recommend replacing the air spool when replacing the gauge or hose.
