The slim-line gauge case is made from nickel plated brass and is complimented by a specially designed housing to protect against accidental damage to the gauge and the HP hose fitting. The material used for the housing has been selected for impact resistance and also because of the high quality finish we can achieve enabling us to offer a luxurious and comfortable feel. There is also a large loop area designed into the housing for ease of attachment.We have thought about every area of the gauge from its functionality to its look. The style of the gauges match Apeks quality regulator ranges such as the XTX range and the new Flight travel regulators. In fact all of Apeks new gauges are ideal for travel as they are compact and slim, but still offer good, clear readings. Even the detail on the back of the gauge housing is finished to match other Apeks products. To ensure you have an authentic Apeks gauge look for the metal "A" badging. These are the same as the badges on our new Flight Travel regulators and can be seen in the gauge pictures below.The dial window is made of highly shock resisitant material (anti-splinter Polycarbonate) to protect your quality gauge. There is an over-pressure capsule fitted in the back of the module to prevent the screen from exploding in the unlikely event of the internal mechanism failing. The gauge fulfils all safety requirements according to EN 250.
