Bauer couplings for agricultural and civil engineering

The Bauer coupling is a large-bore lever-lock fitting used across agriculture, civil engineering and water management. The design uses a hinged locking ring that clamps the male and female halves together — quick to connect and disconnect in field conditions, and secure enough to hold under the flow rates and pressures typical in agricultural and civil work.

Galvanised steel is the standard material, chosen for its resistance to the abrasion and UV exposure that come with outdoor use in agriculture and construction. The coupling is sized to handle the large-bore hoses used in irrigation, dewatering pumps and slurry transfer — applications where you need high flow and frequent reconnection.

Compatibility between manufacturers is generally good, but not universal. Most Bauer couplings conform to a broadly common standard, but check coupling-to-coupling compatibility if you are mixing makes across a system.

The range here covers both male and female halves across standard sizes. End fittings to attach the coupling to a specific hose type are available separately — check the bore and end specification of your hose before ordering.

Frequently Asked Questions

What are Bauer couplings used for?

Bauer couplings are used in agricultural irrigation, civil engineering dewatering, and slurry transfer. They connect large-bore hoses quickly using a lever-lock ring and are designed for repeated use in outdoor environments.

Are Bauer couplings compatible between different manufacturers?

Most Bauer couplings conform to a broadly common profile, but compatibility between manufacturers is not always guaranteed. If you are mixing Bauer couplings from different brands across a system, check that the male and female halves mate correctly before deploying them.

What material are your Bauer couplings?

Galvanised steel. This suits outdoor agricultural and civil engineering use where corrosion resistance and physical robustness are required.

Do you deliver Bauer couplings near me?

Yes. We deliver across England and Wales with free delivery on orders over £200.
