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. 316 stainless steel fittings have excellent 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.
