The Plasson Threaded Reducing Bush 5027 (3/4in x 1/2in) is a precision-molded female-to-male BSP threaded adaptor designed to reduce the internal thread size of a fitting, valve, or manifold port. It is widely utilized by plumbing, irrigation, and utility professionals to step down a larger 3/4-inch female threaded outlet to accept a smaller 1/2-inch male threaded connection, offering a compact and non-corrosive alternative to brass or metallic bushings.
 
Manufactured from high-grade virgin polypropylene, this reducing bush provides exceptional impact strength, environmental stress resistance, and complete immunity to rust and electrochemical corrosion. Featuring a 3/4-inch male BSP thread on the exterior and a 1/2-inch female BSP thread on the interior, it ensures a tight, high-integrity joint when used with appropriate PTFE tape, jointing compound, or washer seals.
 
Engineered for rapid, space-saving installation, the integrated hexagonal shoulder allows for secure tightening with standard spanners or wrenches. Fully WRAS-approved for wholesome potable water supply and rated for high working pressures up to 16 bar (PN16), this trade-quality reducing bush delivers reliable, long-term, leak-free performance across domestic, commercial, and agricultural fluid infrastructure.
