Profec - Brass Hose Tail Adaptor 3/4" Male Thread x 20 mm 30 bar - 0411818

Profec – Brass Hose Tail Adaptor 3/4″ Male Thread x 20 mm 30 bar

Rated to a robust 30 bar working pressure and tolerant of temperatures up to 120 °C, this solid brass hose tail adaptor from Profec bridges a 3/4″ male BSP thread to a 20 mm hose tail in a compact 41 mm body. It is a reliable choice for pool plant rooms, heat pump pipework, filter headers, and any pressurised water circuit where a rigid-threaded port must transition cleanly to flexible hose.

Construction & pressure rating

Machined from full brass and sized for a 27 mm spanner, the adaptor delivers exceptional corrosion resistance in both chlorinated and untreated water systems. The 30 bar pressure ceiling comfortably exceeds the demands of domestic and light-commercial pool installations, making it equally suitable for chemical dosing lines, backwash circuits, and heat exchanger connections.

Connection geometry

The 3/4″ male thread engages directly with standard BSP female ports on pumps, valves, filter multiport valves, and manifold blocks, while the 20 mm barbed hose tail retains flexible reinforced hose securely — ideally finished with a stainless steel hose clip. At just 41 mm in overall length, the fitting keeps pipework tight and well-organised even in confined equipment bays.

Temperature & compatibility

With a maximum service temperature of 120 °C, this adaptor is fully compatible with heat pump and solar heating circuits, not merely ambient pool plumbing. Profec is a specialist European fittings manufacturer whose brass hydraulic components are widely used by professional installers across pool, HVAC, and industrial fluid-handling applications.
