Installation Instructions For DIN Tube Fitting Assembly

The nuts of Beyond Fluid DIN 2353 hydraulic fittings are all silver plated, and spray nano lubricating layer with our own patent . In this way, the installation torque can be controlled within a reasonable range. Especially in the case of narrow space or suspended operation, it makes installation very easy. For proper assembly following assembly instruction shall be followed. Improper assembly may lead to malfunctions or impair safety.
Cut The Tube
Assembly in Fitting Body

Assembly in Fitting Body

Tube Preparation Instructions
  1. Cut the Tube:
    An angle tolerance of ±1/2˚ to the tube axis is permissible. The use of a tube cutter is not recommended.
  2. Remove Burrs and Particles:
    Lightly remove chips and particles from both the inner and outer cut edges of the tube. A bevel up to 0.2 mm × 45˚ is permissible.
  3. Tube Bending Requirement:
    The minimum length from the straight end of the tube to the start of the bending radius must be at least twice the height of the nut.
  4. Lubrication:
    Lubricate the thread and cone of the fitting body, as well as the ring and thread of the nut.

Final DIN Tube Assembly

  1. Slip nut and then ring onto the tube end. Ensure that the ring is placed correctly.
  2. Screw nut manually onto fitting body until finger tight. Hold the tube against the shoulder in the cone of the fitting body.
  3. Mark nut and tube for measuring the prescribed turns of the nut.
  4. Tighten the nut 1 1/4 turns. Tube must not turn with tube. Stop edge of the ring limits over-tightening by increasing tightening torque.
  1. Loosen nut and remove ring-mounted tube from fitting. And check if a visible collar has formed on the pipe in front of the first cutting edge. If not, tighten slightly more.
  2. Insert the pre-assembled tube into the fitting.
    While holding fitting body with a wrench, tighten nut approx. 1/4 revolution beyond the point of a clearly perceptible resistance.
