  • Material

  • CA360 Brass
  • Used With

  • NT Nylon Tubing - SAE J844 Type A and B.
  • Tolerance

  • +/- .02 on all dimensions. Dimension Data can change without notice. Please contact us when dimensions are critical.
  • Conformance

  • Advantages
    Easy to assemble (no tube preparation or flaring required.) Built in tube support. May be used with copper tubing by replacing nut, sleeve and insert with long nut and spherical sleeve. Insert should be removed for copper tubing use.

Assembly Instructions
  1. Cut tubing to desired length.
  2. Slide nut and then sleeve on tubing. Threaded end of nut must face toward fitting body.
  3. Insert tubing into the preassembled fitting. Be sure tubing is bottomed in fitting.
  4. Tighten nut to required torque as indicated on chart.
Disassembling: Remove nut and pull tubing out of fitting body. Insert will remain in tubing.
Reassembly: Push tubing and insert into fitting body until it bottoms. Thread nut onto fitting body and torque as in step 4.
