Bauer S77 - Quick Coupler Adaptor Galvanised Steel 133mm × 125mm Male Bauer × Hose Tail - 0220436

Bauer S77 Quick Coupler Adaptor Galvanised Steel 133 mm × 125 mm Male Bauer × Hose Tail

This large-bore S77 adaptor bridges a 133 mm male Bauer ball fitting to a 125 mm hose tail, making it one of the largest standard sizes in the Bauer galvanised steel range and suited to high-volume water transfer duties — including pool plant bypass lines, dewatering, and pump suction or discharge connections. The hot-dip galvanised steel construction delivers dependable corrosion resistance wherever sustained contact with water is expected.

Ball-and-socket coupling system

Bauer-type fittings use a ball-and-socket connection secured by a lever-closure ring, allowing the joint to be made or broken by hand without any tools or loose hardware. The coupling accommodates a degree of angular offset at the joint, which simplifies alignment in congested plant rooms or on site where hose routing is awkward.

Hose tail connection

The 125 mm hose tail end is designed to be pushed into a compatible large-bore lay-flat or suction hose and secured with a hose clamp or clip, providing a leak-resistant seal under both suction and positive pressure. This makes the adaptor particularly practical for temporary or semi-permanent connections to pump sets, where fast assembly and disassembly are priorities.

Material & surface finish

Manufactured from steel with a galvanised surface treatment, this fitting offers solid mechanical strength for demanding transfer duties. The galvanised finish provides a serviceable level of corrosion protection in outdoor and poolside environments, though the fitting should be inspected periodically if used in heavily chlorinated or saline water service.
