Midland Industries 38970 Type B Air Brake Tubing 5/8in 100ft

Product Description

The MIDLAND INDUSTRIES 38970 is a Type B reinforced nylon air brake tubing designed for use in commercial vehicle air brake systems. Constructed from nylon with a 0.092-inch wall thickness, this tubing delivers a 150 psi working pressure rating and handles a wide service temperature range of -40 to 200 degrees F. The 5/8-inch nominal diameter coil measures 100 feet in length and weighs 6.82 pounds, giving technicians a full working supply for routing, repair, or new installations. Licensed fleet mechanics and brake system technicians are the primary installers.

This tubing is suited for air brake line applications on Class 4 through Class 8 trucks, trailers, and heavy equipment where DOT-compliant brake system plumbing is required. The black nylon construction is specified for exposed or semi-exposed routing runs where UV, ozone, and abrasion resistance are priorities. Cold-weather flexibility down to -40 degrees F makes it viable for year-round service in northern climates without special handling accommodations.

Key Features

• Type B reinforced nylon construction rated to 150 psi working pressure
• 0.092-inch wall thickness for durability in high-vibration environments
• Operating range of -40 to 200 degrees F with rated cold-weather flexibility
• UV, ozone, and abrasion-resistant outer surface for exposed routing
• 5/8-inch nominal diameter in a 100-foot continuous coil
• Black color for standard-spec compliance and heat absorption resistance

Compatibility

Designed as a Type B air brake tubing replacement or new-install supply for commercial vehicles and heavy equipment requiring 5/8-inch nominal nylon air brake lines meeting DOT FMVSS 106 category specifications.

Installation Notes

Air brake tubing installation and repair must be performed by a qualified brake system technician familiar with FMVSS 106 and applicable CVSA regulations. Always depressurize the air brake system completely before cutting or disconnecting any tubing. Use proper nylon tubing cutters to ensure a clean, square cut at all fittings to prevent leaks. Verify all fitting connections with a system pressure test before returning the vehicle to service.
