Plugs and connectors are used to close unused outlets on manifolds, blank off branch lines, or temporarily cap fittings during winter lay-up. Available in bronze, chrome-plated brass and stainless steel, with male or female thread in sizes from ½" to 2".

When to use a blanking plug

In any marine plumbing circuit you will end up with outlets or branches that need to be temporarily sealed: unused legs of a T-fitting, optional service connections, or circuits that are isolated for winter lay-up. A good blanking plug prevents leaks and protects the receiving thread.

Available types

Male plug: external thread, screws into a fitting with internal thread.
Female plug / cap: internal thread with hex or flanged head, fits over a male end.
Male-male / female-female connectors: to join two fittings with the same thread termination.

Materials

Bronze is the standard choice for raw water circuits. Chrome-plated brass is reserved for pressurised fresh water plumbing and visible deck finishes. AISI 316 stainless is suitable for services without continuous contact with stagnant water.

Sealing

Apply PTFE tape on parallel BSP threads and anaerobic thread sealant on tapered BSP. Avoid natural hemp packing in marine circuits — it traps moisture and accelerates corrosion.
