The Gruvlok Fig. 7788 Flange Adapter allows for direct
connection of Class 125 or Class 150 flanged components to a
grooved piping system. The Gruvlok Flange Adapter provides
an alternative method of connecting to flanged components
than the traditional Fig. 7012 Gruvlok Flange. The Gruvlok
Flange Adapter provides a raised serrated face flange
connection with a shorter overall length than Anvil’s Fig. 7084
Flange x Groove Nipple.
