Union nut for cutting ring, tube 6 S, zinc-plated steel, heavy series

The union nut presses the cutting ring onto the cone of the stud as it is tightened and so holds the tube in the coupling. The stated material is zinc-plated steel. The data sheet gives a working pressure of 630 bar. This version is supplied with heavy series.

Benefits

• Matches tube 6 S (M14x1,5) of the heavy series, so the nut fits the cone of the matching stud.
• Available as a single part, so a damaged nut can be replaced without changing the whole coupling.
• For working pressures up to 630 bar in this size.
• Temperature range -40 to +120 °C, made of zinc-plated steel.
• The hexagon allows tightening with an ordinary open-ended spanner, no special tool is needed.

Applications

When assembling a line 6 S (M14x1,5) the nut draws the cutting ring in and cuts it into the tube.

Standards and conformity

The stated temperature range -40 to +120 °C applies to the version in zinc-plated steel. An elastomer seal narrows it.
