Screw-On Hose Fittings for Hydraulic Fluid
These two-piece fittings screw directly onto rubber hose without the need for a separate adapter. To install, separate the two pieces of the fitting (the hose-end portion and the nipple portion). Screw the hose-end portion of the fitting onto the hose, then thread the nipple portion of the fitting into the hose-end portion. When assembled, the fitting compresses against the hose, forming a strong seal. Also known as reusable fittings, they can be unscrewed from the hose end and used on a new hose.
Zinc-plated steel fittings offer better strength and durability than 316 stainless steel fittings. They have fair corrosion resistance. 316 stainless steel fittings have excellent corrosion resistance.
Fittings with a 37° flared end are also known as JIC (Joint Industrial Council) fittings. They swivel 360° until tightened for easy installation.
NPTF (Dryseal) threads are compatible with NPT threads.
Notes: Fittings are only for use with hydraulic hose.
