Series RH

The flat-face screw-to-connect cpuplings in the RH series from STAUFF consist of a coupling sleeve with an external thread and a coupling plug with a screw sleeve. Developed for the heaviest hydraulic applications up to DN25 (1"), they enable safe and easy coupling (screwing) and uncoupling (unscrewing) without tools.
Thanks to the flat-face design, the risk of leaks is minimised and the service life of the connection is significantly increased.

Once fully connected, all internal components have minimal play, which reduces material fatigue. In addition, the risk of "brinelling" - permanent indentations on the surface of the plug - is eliminated, a typical problem with extremely stressed plug-in couplings.

The flat-face screw-to-connect cpuplings of the RH series are available in several nominal widths to meet different requirements. Sizes DN10, DN12.5, DN16, DN19 and DN25 (equivalent to 3/8" to 1") are available as standard. This allows both smaller hydraulic lines and large-volume systems to be connected safely and reliably.

Depending on the application, various sealing materials (FKM/Viton®, HNBR and PTFE) are available to ensure high chemical and thermal resistance. Thanks to the modular design, coupling sleeves and plugs can be flexibly combined and customised to individual requirements.

• Safe operation thanks to minimised component play - Protection against material fatigue

• Prevents permanent "brinelling" on the plug

• flat-face design for clean, drip-free coupling

• Reliable corrosion protection thanks to zinc/nickel coating

• Suitable for stationary and mobile applications

The RH series screw-to-connect cpuplings comply with common market standards and have been established as an original Voswinkel product for many years. They are available in nominal sizes 10, 12.5, 16, 19 and 25 (3/8" - 1") and are interchangeable with comparable flat-face screw-to-connect cpuplings.
