Functional nut with cutting and sealing ring, tube 20 S, FKM seal

Once installed, the functional nut combines union nut, cutting ring and elastomer seal in a single part and seals softly on the tube. The data also state the tube size 20 S. The stated figure is a working pressure of 400 bar.

Benefits

• Cutting ring and seal come ready fitted, so the joint on tube 20 S needs no separate parts to be presented first.
• The functional nut FKM version sets the elastomer material of the additional soft seal.
• Tube 20 S belongs to the heavy series and sets the cone and the thread of the nut.
• The working pressure of 400 bar applies to the fully tightened joint.
• The additional soft seal takes up settling that a purely metallic seal on tube 20 S cannot compensate.

Applications

On systems running at 400 bar the extra elastomer seal keeps the joint tight even under pressure surges.
