VAGT® Details

Metal to metal seal
The high contact pressure in the seal area is reinforced by the internal shoulder and ensures gas tightness at tensile loads up to the joint tensile strength.

Improved buttress
The tapered buttress thread ensures a high stress performance and allows easy make-up even under severe conditions.

Robust internal shoulder
The internal shoulder reinforces the contact pressure in the seal area and acts as a positive make-up stop.

Smooth internal shoulder
The flush internal profile minimizes turbulence. It also provides good conditions for internal plastic coating.
