Screw-On Hose Fittings for Hydraulic Fluid
With just a vise and a wrench, make or repair hose assemblies in the field. These fittings thread directly onto hydraulic hose, so you don't need to crimp. To install, separate the two pieces. Screw the hose end onto your hose first and then thread the two pieces of the fitting back together. 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 again.
Fittings with a female tube end swivel 360° until tightened for easy installation.
Fittings with a 37° flared end are also known as JIC (Joint Industrial Council) fittings.
Zinc-plated steel fittings are stronger and resist wear and tear better than 316 stainless steel fittings. The zinc plating resists rusting in wet environments.
NPTF (Dryseal) threads are compatible with NPT threads.
Note: Fittings are only for use with hydraulic hose.
