This gasket made of EPDM material is specially shaped for installation under a stub flange of 125 mm diameter when assembling a flanged joint on PVC pipe.
EPDM (ethylene-propylene-diene rubber) is the standard sealing material for pool applications — it resists chlorine, ozone, UV radiation and temperatures from freezing winters to hot summer periods.
The correct use of this gasket is a precondition for achieving full tightness and the declared pressure class of the flanged joint. The gasket requires no lubrication or special products — it is fitted dry between the flange and the stub.
