Threaded Hose Fittings for Hydraulic Fluid
Fittings are threaded on both ends so you can connect them directly to a threaded hose or to pumps, cylinders, and other equipment in your hydraulic system.
Zinc-plated steel fittings are stronger and more durable than stainless steel fittings. They have fair corrosion resistance. Fittings that swivel until tightened rotate for easy installation.
Fittings with a 37° flared end are also known as JIC (Joint Industrial Council) fittings.
BSPP threads have a gasket or a 60° internal flare to protect against leaks.

Continuous-Swivel Threaded Hose Fittings for Hydraulic Fluid
Also known as live swivels, these fittings have ball bearings, so they can swivel continuously 360° before and after installation. This not only makes installation easier, but also eliminates the twisting and kinking that can cause premature hose failure. Fittings are threaded on both ends so you can connect them directly to a threaded hose end or to pumps, cylinders, and other equipment in your hydraulic system. They are zinc-plated steel, which has excellent strength and durability. Fittings have fair corrosion resistance.
Fittings with a 37° flared end are also known as JIC (Joint Industrial Council) fittings and meet JIC standards for dimensions.
NPTF (Dryseal) threads are compatible with NPT threads.

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.
Notes: Fittings are only for use with hydraulic hose.
