Bauer style ball and socket couplings are specialty connections, designed primarily for use in dewatering, construction, irrigation and other agricultural applications. These fittings were originally invented in 1947 in Austria by Rudolf Bauer, as a way to quickly couple water transfer hose and pipe together. Amazon Hose & Rubber Company stocks a wide range of these lightweight, durable hose ends and adapters in sizes ranging from 4” to 8,” with other sizes available upon request.

Bauer style fittings are more easily deployed in the field than cam and groove couplings or bolted flanges. Cam and groove fittings and bolted flanges require perfect alignment for connection. By contrast, Bauer style fittings can be coupled at offsets of up to 30 degrees depending on the diameter of the line.

• Ball
