Description:
Hobas sealtight couplings are produced using a winding process. To achieve the same quality standard as the pipes, they incorporate a full width epdm seal (gasket). The couplings are manufactured on a computerized machine, which first places the prefabricated epdm gasket on a steel mold and then winds glass roving pre-saturated in polyester resin round it.
At the same time cut roving is sprinkled on to the coupling to reinforce the axial direction. After the laminate is in place, the resin is polymerized by applying heat.
