Yor-Lok Fittings for Stainless Steel Tubing
A nut with two sleeves (ferrules) gives these fittings extra gripping power. The sleeves bite into tubing as you tighten the nut, creating a strong seal. Also known as instrumentation fittings, they are made to tight tolerances for use in high-precision applications. They are compatible with Swagelok®, Let-Lok, and A-Lok fittings.
316 stainless steel fittings have excellent corrosion resistance.

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