Midland Industries 25002 Split Sleeve Collet 3/16 in Brass

Product Description

The MIDLAND INDUSTRIES 25002 is a brass split sleeve collet designed for 3/16-inch compression connections in pneumatic and fluid transmission line systems. This collet grips and secures nylon tubing at compression fittings, maintaining a leak-free seal under pressure and temperature cycling. Rated to 150 psi and a temperature range of -40 to 220 degrees F, it is built for the demanding conditions found in vehicle air brake and transmission line applications. Plumbers, fleet mechanics, and pneumatic system technicians install this type of fitting hardware during line assembly or repair.

The 25002 is specified for use with SAE J844 Type A nylon tubing, which is the standard tubing type used in DOT-compliant air brake and transmission systems on commercial and light-duty vehicles. It fits into split sleeve transmission fitting assemblies where the collet provides the grip force on the tubing OD as the fitting is tightened. This part is categorized under Split Sleeve for Transmission DOT fittings, making it appropriate for federally regulated brake and air line installations.

Key Features

• 3/16-inch compression connection size for precise tubing engagement
• Rated to 150 psi working pressure
• Temperature range of -40 to 220 degrees F for under-hood and outdoor environments
• Brass construction for corrosion resistance and long service life
• Compatible with SAE J844 Type A nylon tubing per DOT transmission fitting standards
• Split sleeve design allows positive tubing retention without special tooling

Compatibility

Designed for use with SAE J844 Type A nylon tubing in split sleeve transmission DOT fitting assemblies. Consult fitting assembly documentation to confirm collet size matches tubing OD and fitting series before installation.

Installation Notes

Installation is typically performed by qualified mechanics or pneumatic system technicians working on DOT-regulated air brake or transmission lines. Depressurize the system completely and relieve all air pressure before disassembling any fitting. Ensure the nylon tubing is cut cleanly and squarely before seating it through the collet and into the fitting body. Follow applicable DOT and SAE guidelines for air brake line assembly and inspection after any fitting service.
