Product description
Made from UV-stabilised, weather-resistant plastic, this double-ended adapter comes with 3/4″ BSP male threads on both sides, plus a back nut and washer to ensure a secure, leak-proof installation. It’s designed to accept any female BSP fitting or tap directly, providing a versatile solution for rainwater harvesting systems and outdoor fluid-storage setups. The precision-cut threads engage smoothly with your tank’s BSP boss, while the external washer and nut lock the fitting firmly in place—preventing leaks even under pressure.
Fitting is fast and tool-free: drill a 26 mm hole if needed, push the adapter through the wall, slide on the internal washer, then tighten the back nut from the outside until the external washer seals against the tank. No sealants or extra parts are required. Ideal for both new installations and upgrading existing systems, this connector delivers dependable performance indoors or out, and lets you attach hoses, taps or quick-release couplings in seconds.
