Quick Coupler Adaptor Galvanised Steel 89 mm × 75 mm Male Bauer S77 x Hose Tail

At 89 mm on the Bauer male side and 75 mm on the hose-tail end, this galvanised steel S77 adaptor bridges a large-diameter Bauer quick-coupling system to flexible hose — covering pool backwash lines, dewatering runs, and irrigation feeds in a single robust fitting. The hot-dip galvanised finish protects against corrosion in wet or outdoor environments, making it well suited to the permanently damp surroundings of a pool plant room or outdoor equipment pad.

Bauer S77 Connection System

The S77 is a male-half Bauer quick-coupler profile — a ball-and-socket style coupling that locks and releases by hand in seconds, with no loose parts or tools required. Once mated to a compatible female Bauer fitting, the joint can articulate to accommodate slight misalignment between pipework runs, which is particularly useful when connecting rigid pool-side pipework to a flexible discharge or bypass hose.

Construction & Corrosion Resistance

The adaptor is machined from steel and finished with a galvanised surface treatment, combining the strength needed for pressurised pool and water-transfer duties with meaningful resistance to rust in humid plant-room conditions. The 89 mm coupling face suits the 3½″ Bauer standard commonly found on larger pool backwash headers and dewatering pump outlets, while the 75 mm hose tail accepts heavy-duty lay-flat or suction hose secured with a hose clamp.

Sizing & Typical Applications

This 89 × 75 mm size is appropriate for high-flow pool backwash discharge lines, temporary dewatering during pool construction or maintenance, and seasonal irrigation or water-transfer systems that use the Bauer quick-connect standard. Because Bauer couplings are a widely adopted open standard, this adaptor is cross-compatible with Bauer-type fittings from multiple manufacturers, giving installers flexibility when assembling or extending an existing system.
