SAE J246 Spherical Flanged Sleeve Compression Tube Fittings standard

Date:Jul 10, 2019

SAE J246_201711 is standard for Spherical and Flanged Sleeve (Compression) Tube Fittings.


This SAE J246 Standard covers complete general and dimensional specifications for tube fittings of the spherical and flanged sleeve compression types for use in the piping of air brake systems on automotive vehicles.

The spherical sleeve compression type Figures 1A to 5 and Tables 1 to 3 is intended for use with annealed copper alloy tubing per SAE J1149, Type 1.

The flanged sleeve compression type Figures 6A to 11 and Tables 4 to 6 is intended for use with nylon tubing per SAE J844. It is not intended to restrict or preclude other designs of a tube fitting for use with SAE J844, air brake tubing.

Performance requirements for SAE J844 are covered in SAE J1131.

See SAE J1131 for the Performance Requirements of Reusable (Push to Connect) Fittings Intended for Use in Automotive Air Brake Systems.
