HOUSING EXTENSION &
WEH JAW LOCKING MECHANISM

Thanks to the extended body, the WEH Clamping Jaws grip and seal the interior diameter of the tube directly behind the expanded tube end thus being independent from the surface finish of the expanded tube end.

CONNECT TO A LARGE VARIETY OF TUBE ENDS

The TW231 reliably seals copper, aluminium or steel tubes with expanded tube end profiles, i.e. swaged, flared or beads. The original WEH Clamping Jaws provide maximum grip and minimal distortion to the test piece.

HIGH QUALITY MATERIALS

Manufactured in Germany and made of high grade materials, the connectors are built to last and offer increased longevity and ruggedness.

CLAMPING LEVER

The clamping lever actuation creates an instant seal to the interior tube diameter of the extended tube end profile without tedious hand-tightening - Just in seconds
