Buy flat-face screw-to-connect cpuplings of the RH series made of steel in the online shop

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.

Product features

The RH series screw-to-connect cpuplings offer numerous technical advantages:

  • Flat-face design for minimised leakage and clean coupling

  • Made of steel with high-quality zinc/nickel surface coating for reliable corrosion protection

  • Seals made of PU, NBR and PTFE for high chemical and thermal resistance

  • Heavy-duty internal components for extreme operating conditions

  • Suitable for bulkhead mounting

Product variants and sizes

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.

Applications and areas of use

The RH series is particularly suitable for the following areas of application:

  • Construction and transport modules

  • Drilling rigs

  • Towbars

  • Hydraulic systems in the oil and steel industry

  • Demanding stationary and mobile hydraulic applications

Advantages and unique selling points

  • 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

Standards and interchangeability

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.
