• Available as a single part, so a damaged nut can be replaced without changing the whole coupling.
• For working pressures up to 315 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.

Standards and conformity

Before assembly the stud thread and cone, the inside of the union nut and the cutting ring are oiled. Thin-walled or soft tubes need a reinforcing sleeve.
