Straight female stud coupling, G 3/4", tube 20 S, stainless steel 1.4571, no nut or ring

Once installed, the female stud coupling connects a precision tube through a cutting ring to a parallel G female thread. This version is listed with female thread G 3/4" and tube connection 20 S (M30x2). Its rating is a working pressure of 400 bar. The version is listed with heavy series and scope of delivery without nut and cutting ring.

Benefits

• Female thread G 3/4", so the tube screws onto an existing male thread without drilling the device.
• Tube connection 20 S (M30x2) in the heavy series.
• Working pressure up to 400 bar in the straight through form.
• Temperature range -60 to +400 °C for the version in stainless steel 1.4571.
• When tightened the cutting ring bites into the tube and holds it by both form and friction.

Applications

When rebuilding a line of the heavy series the male thread on the device stays as it is and only the coupling is changed.

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.
