Installed worldwide since, 1962, the Simpliport boiler water level glass gages provide reliable direct-reading, bi-color indication up to 3,000 psi (206 bar). Where you may be standing within 180 degrees of the Simpliport hood - which includes spiral-wound sealing gaskets and requires no hot-torquing - you can clearly see the bright red or green indication of steam and water level. You'll decrease your exposure time to the boiler environment while maintaining a crystal clear view of a direct reading gage as required by ASME.
