AIR BRAKE FITTINGS

Typical Application: Air brake systems except where temperatures exceed +200°F or where battery acid can drip on tubing. Pressure: Maximum operating pressure of 150 psi. Vibration: Fair resistance. Temperature Range: -40°F to +200°F (-40°C to +93°C) Material: CA360 Brass. Used With: Air Brake Tubing. 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.  Meets specifications and standards of SAE and DOT FMVSS 571.106.

How to Order: For complete assemblies (body, nuts and sleeves), order by catalog number. Example: 1468-4-4. Nuts, sleeve and insert can be ordered separately by catalog number.

Configurations and dimensions subject to change without notice. Additional information can be found in SAE J246. Assembly Instructions: 1. Cut tubing to desired length. 2. Slide nut and then sleeve on tubing. Threaded end of nut “A” must face toward connector body. 3. Insert tubing into the pre-assembled fitting. Be sure tubing is bottomed in connector. 4. Tighten nut to required torque as indicated on chart. Another check on proper assembly is dimension A also noted on chart. A gauge ring also assures installation to specification.  Tube A Size Torque Dimension 1/4 85 to 115 in. lbs. .085/.105 3/8 12 to 17 ft. lbs. .125/.145 1/2 25 to 33 ft. lbs. .100/.120 5/8 26 to 35 ft. lbs. .115/.135 3/4 38 to 50 ft. lbs. .180/.200 Disassembly: Remove nut and pull tubing out of connector body. Insert will remain in tubing. Reassembly: Push tubing and insert into connector body until it bottoms. Thread nut onto connector body and torque as in Step 4.
