Member of the Insert Series
The Glass
Pipe Insert is an all fluoropolymer (PTFE/FEP/PFA) check
valve with a FEP
encapsulated spring. The valve is designed to
replace the gasket normally used with glass pipe connecting
flanges. It is inserted into one end of the glass
pipe and the flange bolts are tightened. No extra
pipe fittings are necessary to install a GPI in the
line. The valve works equally well in any position
with proper spring selection, which facilitates installing
a check valve anywhere in the system.
