Metal Barbed Hose Fittings with Kink Absorber for Air and Water
Eliminate sharp bends at the end of your air and water hose—these fittings have a built-in kink absorber. The kink absorber reduces strain on your line, preventing damage. To install, slide the kink absorber onto your hose then push the barbed end of the fitting into the hose. The fitting's barbed end also has threads that connect the kink absorber, hose, and fitting all together. As you thread on the kink absorber to the fitting, it compresses against the hose, forming a strong seal.
Fittings that swivel until tightened rotate, so you don’t need to twist your hose during installation.

Screw-On Hose Fittings for Air and Water
The female connector screws directly onto rubber hose without the need for a separate adapter. You’ll need a female connector (ferrule) and a male adapter (stem) with the same hose ID to make a connection. Screw the female connector onto hose, then thread the male adapter into the female connector. 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.
Brass fittings are softer than 303 stainless steel fittings, so they’re easier to thread together. They have good corrosion resistance. 303 stainless steel fittings have better corrosion resistance than brass fittings.
NPTF (Dryseal) threads are compatible with NPT threads. BSPP adapters come with a Buna-N gasket to form a tight seal. This gasket resists grease, hydraulic oil, motor oil, mild chemicals, and water.

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.

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. Fittings are zinc-plated steel, which is strong and durable with fair corrosion resistance.
Fittings with intermittent swivel rotate 360° until tightened for easy installation.
