SMALL DIAL - HIGH PRESSURE INDUSTRIAL SERVICE GAUGE The model 11/15H is manufactured to meet the demand for small high quality gauges designed for applications using gases, water or any liquid that does not attack brass , bronze or Stainless Steel The one piece polycarbonate case with integral window forms a solid baffle in front of the Bourdon tube and incorporates a full diameter stainless steel blow-out back so that in the event of a tube failure through corrosion, explosion or gross over pressure any vapour or debris is vented from the back of the case. This gauge is designed for fitting into a panel, and is held in place by a screwed plastic clamping ring which screws around the outside of the case providing very easy fixing. The transparent front flange assumes the colour of the panel. For oxygen applications these gauges must be manufactured to ensure they are entirely free from oil and grease.
