Short descriptionWEH® ultra-high-pressure fittings ensure leak-free connections of tube components. The cone-and-thread (Cone & Thread) fittings provide a simple and reliable connection system. All fittings are supplied complete with matching pressure rings and screws.
Features- Metal-to-metal sealing and re-usable
- Pressure ranges up to 10,000 bar / 150,000 psi
- Suitable for media of Fluid Group 2 (per PED 2014/68/EU): air, water and hydraulic oil
- Compatible with standard tube sizes 1/4", 3/8" and 9/16"; available with metric and imperial threads
- Pressure rings and pressure screws are pre-assembled on all connections
Design and tightnessFor pressure ratings 2,500 bar (35,000 psi) and 4,200 bar (60,000 psi) the connection is made with a 58° external cone on the tube end into a 60° internal cone in the fitting. For the 7,000 bar and 10,000 bar ratings special high-seal fittings with a 120° internal cone and 116° external cone are used. WEH provides the required tools for preparation of the tube end (forming/reworking the external cone) and for repair of the internal cones.
T-fitting (product details)T-fitting with three identical ports, available with common high-pressure connections. Two diagonally arranged mounting holes; identical hole pattern for elbows, tees and crosses facilitates system modification and expansion. Connection geometry: High Pressure Fittings 60° Cone & Thread. Special versions with different thread types, pressure ranges or special materials available on request.
