Conversion table

Original BAUER pipes and accessories cover almost any requirement in this field of application. Our pipes and fittings are galvanized according to DIN EN ISO 1461.

Fast and easy to install.

With up to 30° articulation on the coupling joint the pipes adjust easily to the site and ground conditions without loss of suction and pressure integrity. The sealing ring is captive in the coupling socket.

HK couplings are coupled and uncoupled with a few simple hand movements and require no special skills or tools.

Top quality “in house“ production

Since its development by Rudolf BAUER over 50 years ago, several attempts have been made to copy the BAUER HK quick coupling but none of the imitations ever reached the quality and durability of the Original.

This high BAUER quality level results from the incompromising use of high-grade materials and the company’s own production and quality control on pipe mills specifically designed for thls purpose.

Millions of BAUER HK quick-coupling pipes prove their value in tough industrial and agricultural applications throughout global markets.
