How to Identify and Measure Fittings

Pipe size is an industry designation, not the actual size. View information about how to measure threaded and unthreaded pipe and pipe fittings.

Push-On Barbed Hose Fittings for Hydraulic Fluid

These fittings have sharp barbs to grip rubber push-on hose with no clamps or ferrules required. The more you pull on the fittings, the tighter the hose will grip. Use them in low-pressure hydraulic applications up to 350 psi. Also known as hose nipples, they adapt a barbed end to a threaded end, so you can connect to pumps, cylinders, and other equipment in your hydraulic system. Fittings are zinc-plated steel, which has excellent strength and durability. Fittings have fair corrosion resistance.

Fittings that swivel until tightened rotate 360° for easy installation.

Fittings with a 37° flared end are also known as JIC (Joint Industrial Council) fittings.

NPTF (Dryseal) threads are compatible with NPT threads.

Note: To ensure proper connection, the barbed end has to be pushed in all the way, with the hose end concealed by the ring.

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.
