GG90 Series – 90° Rotary couplings (swivel joints)

Holmbury carbon steel rotary couplings are designed for use on hydraulics lines that maybe subject to torsional stress, i.e. moving parts on construction equipment. Using a rotary coupling in the hydraulic line stops the hose twisting , this prevents stress on the hose and can significantly increase the life of it.

If you have a right angle in your hose line, placing a 90° coupling in-line can prevent the use of a bend, reducing the amount of connection (potential weak points) in the line.
