Union nut for cutting ring, tube 4 LL, zinc-plated steel, very light 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. In addition the sheet lists a temperature range of -40 to +120 °C. The stated figure is a working pressure of 100 bar. The version is listed with very light series.

Benefits

• Matches tube 4 LL (M8x1) of the very light 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 100 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.
