The SEWER LOCK integrated joining system involves the formation of the socket on the mandrel and on the gasket, eliminating the tolerances – found in standard products – between the gasket and its seat and ensuring the stability of the ring.
Fitt Sewer EVO uses a socket-and-socket joint system with a gasket mechanically pre-inserted during the socket-forming process. The Sewer Lock® gasket is composed of a sealing element compliant with UNI EN 681, co-molded with a fiber-reinforced polypropylene stiffening ring.
This joining system ensures the absolute immovability of the gasket and guarantees superior performance:
- optimal hydraulic seal
- perfect functionality even in the presence of high misalignments: up to 3° on the joint
- eliminates the need to insert the gasket into the glass
- ensures quick and easy installation
- reduces the assembly force required
- ensures a consistently positive test outcome
- prevents gasket loss
- prevents its damage
