The SpirahelicŪ Direct Drive Pressure Gage is now available with a 316L SS diaphragm. Due to the small volume of the triple wound Bourdon tube inside the SpirahelicŪ gage, a much smaller diaphragm seal may be selected versus a standard "C" Bourdon tube gage. This smaller seal is extremely compact, light weight, and durable which eliminates difficult installation issues with bulky diaphragm seals. These seals are also offered with an optional 1/4" NPT flush port which makes clean outs quick and easy.
