5/32-inch tubing is smaller than standard DOT-regulated brake line sizes (1/4" and larger) and is typically used for signal and gauge lines, not primary brake plumbing. DOT regulations do not apply to fittings in this size; use suitable compression or push-in fittings. Universal fit across makes such as Freightliner, Peterbilt, Kenworth, Volvo, International, etc. when routing auxiliary air lines.

Meets SAE J844 and DOT FMVSS 571.106 material standards. The small-bore size is typically used for low-pressure signal lines, gauge feeds, and secondary air circuits where the larger SAE-recognized brake-system sizes (1/4 inch and larger) are not required. The nylon material resists abrasion, ozone, fuel, chemicals, and under-chassis temperature swings, providing durable performance.
