HK pipes & couplings of Bauer

Galvanized steel. More than 70 years of experience. Pure passion. These are Bauer pipes & couplings. The HK-coupling has been the product which connects all others since the beginning of our history. Reliabel & simple.

In 1947 the Bauer lever closure coupling was born. Even then, the system was unique and a sensation. A coupling, which is easy to use and at the same time absolutely leak proof, was an absolute novelty. Back then, nobody could have guessed that the Bauer system would become an original. In the meantime, countless attempts have been made to copy the invention by Bauer. We consider this as a complement. Reproductions are in circulation worldwide. A specialist will immediately recognize the difference. A nonprofessional maybe only after some time. One thing is certain: no one can match the original.

The original by BAUER

The BAUER HK-quick coupling is available in diameters of 2 to 8 inches, can be bent in all directions, can be coupled extremely quickly and easily and can therefore be found on almost every construction site in the world.

The more sophisticated HKS system meets an extremely high safety standard.

Specially developed thin-walled, but high-strength tubes, together with the BAUER coupling system, guarantee the lowest weight with the highest stability. A complete range of fittings makes the HK system an extremely flexible all-round product.

A unique invention

The connecting element

In addition to the hot-dip galvanized steel version, BAUER couplings are also available in aluminium and stainless steel and in pressure ratings of up to 20 bar. The BAUER system is also very popular in the form of hose connections combined with PE pipes or flat hoses.

Our range of pipes and fittings has been convincing for generations - everywhere and at all times.

 

Original or copy? How to tell the difference:

the name

the name
hk_bauer

The name makes the difference.

Only when the name BAUER is on the lever, is it a genuine, original BAUER clutch!

The strap I
Bauer Hebelverschlusskupplung

Permanently welded

The original BAUER lever is held on the ring by a welded strap. This connection never wears out. It is dimensionally stable and will last a lifetime.

The strap II
Bauer Hebelverschlusskupplung

Permanently welded

On the genuine BAUER coupling, the lug is also permanently welded to the ring at this point. The system is therefore absolutely tight and holds tighter than any other. Copies here are often riveted or need a pin.

Bendable

Bendable

As ball and socket can be twisted, BAUER couplings can be bent by 30 degrees in any direction. A huge advantage on uneven floors.
