Seal and Repair Kits for Couplings

Seal and repair kits keep existing couplings in service: O-rings and back-up rings in the sealing seat, the valve spring, valve poppet, guide bush and locking balls. Wear does not occur on the body but on these parts, caused by every mating cycle, by particles in the circuit and by ageing of the elastomer. A kit costs a fraction of the coupling and can be fitted to the part in place. In a cooling circuit that is not to be drained, that is often the only practical route.

This category exists but does not yet hold any items. Seal and repair kits are tied to a series: one kit fits exactly one coupling size from one manufacturer, and there is no version that spans several series. The range will therefore be built up along the series already carried in this branch. Until then, please give us the manufacturer, series and body size of the coupling in question.
