Union nut for cutting ring, tube 14 S, stainless steel 1.4571

In use, 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 data also state a temperature range of -60 to +400 °C. The stated figure is a working pressure of 630 bar. In addition the data give heavy series.

Benefits

• Matches tube 14 S (M22x1,5) 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 -60 to +400 °C, made of stainless steel 1.4571.
• The hexagon allows tightening with an ordinary open-ended spanner, no special tool is needed.

Applications

In maintenance the nut in stainless steel 1.4571 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.
