Gasket’s come in 3 different ‘types’:
Type E – Full face Gaskets completely cover the flange face from flange bed to outside diameter. These are most commonly used on flat faced flanges.
Type F – Ring Gaskets are designed to sit inside the bold circle and are most commonly used with raised face flanges.
Type D – Ring Joint (RTJ) is an oval phenolic gasket designed to work specifically with RT J grooved flanges. Washer kits also come in 3 options:
Single Washer – allows cathodic protection to reach nuts and bolts.
Double Washer – isolates nuts and bolts from both flanges.
Top Hats – easier to install and gives inspector a visual indication of sleeve usage. Not recommended for high pressure or large flanges that require high torque loads. For pricing enquiries, please provide the following information:
