Bauer S77 - Quick Coupler Adaptor Galvanised Steel 194mm × 200mm Male Bauer × Hose Tail - 0220438

Bauer S77 Quick Coupler Adaptor Galvanised Steel 194mm × 200mm Male Bauer × Hose Tail

At 194 mm on the Bauer side and 200 mm on the hose-tail side, this is one of the largest fittings in the S77 range — purpose-built for high-volume water transfer duties such as pool filling, dewatering, and large-scale irrigation pipework. The male Bauer ball end connects directly to any standard Bauer female socket, while the hose tail provides a secure barbed seat for large-bore layflat or suction hose.

Coupling mechanism & connection

The S77 type uses the proven Bauer ball-and-socket principle: insert the male ball end into the female socket and secure with the locking ring — no tools and no loose parts required. The design permits up to 30° of articulation at the joint, making it forgiving on site where pipework cannot always be perfectly aligned. A rubber seal (typically NR or SBR) completes the joint and keeps the connection pressure-tight and leak-resistant.

Construction & corrosion resistance

The adaptor is fabricated from steel with a hot-dip galvanised surface treatment throughout, providing robust resistance to rust and mechanical wear in outdoor, high-humidity, and splash-zone environments — well suited to permanent poolside or plant-room installations as well as temporary site use. Galvanised steel construction at this bore size delivers the wall thickness and structural rigidity needed to handle working pressures without distortion.

Sizing & compatibility

The 194 mm Bauer interface is compatible with the full range of standard Bauer 194 mm female sockets, including S73 flanged and S78 female hose-tail counterparts, giving installers flexibility when assembling or extending large-bore systems. Always pair with a matching 200 mm bore hose tail and appropriately rated hose clamps to achieve a reliable, full-bore connection.
