Screw-to-Connect Couplings · FT Series

The FT series is a screw-on type coupling for safety and reliable connections for applications in critical and strong areas. This type represents the further development of the VOSWINKEL FH series and combines all the advantages of the FH series of fl at-face quick release coupling.

For example the zinc/nickel surface coating and the environment-friendly construction of the fl at-designed valve unit. Thereby the coupling has extremely small leakage. Operation is possible at extreme pressures up to 550 bar / 7975 PSI (working pressure depends on size).

The main applications of the FT-series are:
· Oil and Gas Industry
  Blowout Preventers (BOPs)
· Mobile and stationary boring installations
· Construction machinery
· High-pressure hydraulics

Tested and certifi ed acc. API 16 D and acc. EUB Directive # 36
