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.
