DGX Black Face Premium SPG, Naked

Designed for easy reading in low light and no light conditions, the needle and large bold markings are luminescent glow-in-the-dark white. The SPG's are otherwise identical to our white 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. Available in two sizes and your choice of PSI or BAR:

• Chrome-plated all brass housing
• Tempered mineral glass face cover
• Bourdon tube mechanism with rack and pinion movement
• Large { 2.375 in | 6 cm } diameter with { 2 in | 5.1 cm } face and { 1 in | 2.5 cm } thickness
• Medium { 2 in | 5 cm } diameter with { 1.75 in | 4.5 cm } face and { 1 in | 2.5 cm } thickness
• Available in PSI or Bar graduations, white or black face

Note these popular gauges are sold under a variety of brand names, but are all manufactured by Termo Industria in Italy.

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.
