Union nut for cutting ring, tube 25 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 article is listed with a working pressure of 400 bar. The stated figures are tube connection 25 S (M36x2). This version is supplied with heavy series.

Benefits

• Matches tube 25 S (M36x2) 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 400 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

In maintenance the nut in zinc-plated steel replaces an over-tightened part without relaying the line.

Standards and conformity

The coupling belongs to the cutting ring system for precision tubes. The tube is cut off square, deburred inside and out and cleaned, and no tube cutter is used.
