Profec - Brass Hose Tail Adaptor 2½" Male Thread × 70 mm 30 bar - 0411778

Profec – Brass Hose Tail Adaptor 2½” Male Thread × 70 mm 30 bar

Rated to a robust 30 bar working pressure and tolerating temperatures up to 120 °C, this large-bore Profec hose tail adaptor bridges a 2½” male threaded port to a 70 mm hose tail — making it well suited to the high-flow pipework found on commercial pool plant rooms, industrial water treatment skids, and large pump installations. At 88 mm in overall length, it provides a solid, leak-free transition between rigid threaded pipework and flexible hose without reducing bore unnecessarily.

Material & pressure credentials

Machined from solid brass, the body combines corrosion resistance with the mechanical strength needed to hold 30 bar without deformation — a significant safety margin over the typical 3–6 bar encountered in pool circulation systems. The high maximum temperature rating of 120 °C means the fitting is equally at home in heating circuits, chemical dosing lines, or hot-water wash-down applications alongside standard pool plumbing.

Connection geometry

One end carries a 2½” male thread (BSP) for direct engagement into a female-threaded manifold, valve, or pump port, while the opposite end presents a 70 mm hose tail barb for securing flexible hose with a clamp or ferrule. The 75 mm spanner flat across the body allows confident tightening without slipping, even in restricted plant-room spaces. Overall body length of 88 mm gives adequate thread engagement and hose grip without adding unnecessary bulk to the assembly.

Sizing & application fit

The 2½” × 70 mm size class is typically found on high-volume pool filtration headers, backwash outlets, and commercial suction lines where flow rates would choke smaller fittings. It is a direct, no-modification replacement for worn or damaged adaptors on equivalent-sized plant, and pairs naturally with 70 mm bore flexible pool or industrial hose secured by a compatible hose clamp.
