3.5" gauge with a rear flange mount. This 5,000 psi gauge comes in handy when a permanent installation is required, but panel mounting is not practical. It can be mounting directly to a wall or similar flat surface. A stainless steel housing with copper allow internals give this gauge a long lasting service life. Connections are made through a 1/4 NPT male lower stem mount connection. Accuracy is +/- 2% full scale. This product is DISCONTINUED and no longer a stocked item for Global. Once current inventory is gone, it will only be available through special order.
