D.O.T. Hose
- Temperature Range: -40° to 300° F
- Maximum Vacuum: 28" of Hg @ 72° F
- Material: Synthetic Rubber with Braided Fiber Cover
- Color: Black
- Compatible Hose Fittings: Parker Series 20
Also known as air brake hose, this hose safely powers brakes in semitrucks, trailers, and other vehicles with compressed air. It meets D.O.T. and SAE testing, performance, and dimensional standards for use in vehicle brake systems. It can also be used in hydraulic, diesel fuel, and coolant systems. Reinforced with braided steel wire and braided fiber, it won’t lose its shape under pressure. A layer of braided fiber also protects the outside of the hose from weather and ozone. This hose is compatible with screw-on fittings, so there’s no need for a crimper. All you need is a vise and a wrench to make hose assemblies in the field.

Screw-On Hose Fittings for D.O.T. Hose
Create or repair D.O.T. hose assemblies in the field with just a wrench and a vise, no crimper required. To install, separate the two pieces of these fittings. Screw the hose-end portion onto your hose, then thread the nipple portion into the hose-end portion. When assembled, these fittings compress against the hose to form a strong seal. Also known as reusable fittings, they can be unscrewed from your hose and used on a new one. All meet labeling and performance requirements for motor vehicle brake hose fittings.
Fittings with a flared tube connection swivel 360° until tightened for easy installation. Those with a 37° flared end are also known as JIC (Joint Industrial Council) fittings. Those with a 45° flared end are also known as SAE fittings.
NPTF (Dryseal) threads are compatible with NPT threads.
