Precision Extreme-Pressure Stainless Steel Threaded Pipe Fittings
Made to tighter tolerances than other stainless steel pipe fittings, these are also known as instrumentation fittings. The male threads are rolled for extra strength in extreme-pressure applications. Fittings are commonly used to connect equipment in gas and hydraulic fluid lines. They are 316 stainless steel for excellent corrosion resistance. UN/UNF (SAE Straight) threads are also known as O-ring boss threads; the male threads have a gasket to prevent leaks.

Metal Push-On Barbed Hose Fittings for Air and Water
Fittings have sharper barbs than standard barbed hose fittings 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.
Brass fittings are softer than other metal fittings, so they’re easier to thread together. They have good corrosion resistance. 316 stainless steel fittings have excellent corrosion resistance, so they’re the best choice for high-humidity environments.
Fittings that swivel until tightened rotate 360° for easy installation.
Fittings with a flared end meet JIC or SAE standards for dimensions. Fittings with a 37° flared end are also known as JIC (Joint Industrial Council) fittings.The optional installation tool (sold separately) allows you to connect large quantities of barbed fittings to push-on hose. Use the built-in cutter to squarely cut the hose without fraying. Next, lubricate either the push-on hose, fitting or both. Then, clamp the hose into the tool’s vise and apply light pressure on the handle to drive into the fitting.
Note: To ensure proper connection, the barbed end has to be pushed in all the way, with the hose end concealed by the ring.

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.

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.
316 stainless steel fittings resist corroding from harsh chemicals and water better than zinc-plated steel fittings.
Note: Fittings are only for use with hydraulic hose.

Crimp-On Hose Fittings for Hydraulic Fluid
Crimp these fittings onto hydraulic hose for a permanent, leak-tight connection. Since they crimp on, they handle higher pressure than screw-on fittings. To install, use Parker crimping tools and dies (not included).
Fittings with a female end swivel 360° until tightened without you needing to move or twist the entire hose, making them easy to install.

International Standard ISO B Quick-Disconnect
Hose Couplings for Hydraulic Fluid
A complete coupling consists of a plug and a socket (both sold separately) that connect and disconnect quickly. Use them if you need frequent access to a hydraulic hose line. All of the International Standard ISO B quick-disconnect plugs are compatible with any of the International Standard ISO B quick-disconnect sockets of the same coupling size, regardless of the pipe size. Couplings meet ISO 7241-1 Series B dimensional and performance standards and are compatible with Parker 60 couplings. Also known as double shut-off couplings, the plugs and sockets both have a shut-off valve that stops the flow when the coupling is separated.
Plugs are also known as nipples.
Zinc-plated steel is stronger and more durable than other metals. It has fair corrosion resistance.
Note: To ensure a correct fit, make sure that the plug and socket have the same coupling size. Pressure ratings are given for static (constant) pressure conditions.
Warning: Never attempt to connect or disconnect couplings when operating at maximum pressure. Stop the flow before you disconnect the line.

- Temperature Range: -60° to 400° F
- Tubing: Use with seamless aluminum
Also known as JIC (Joint Industrial Council) fittings, these provide a tight metal-to-metal seal on tubing that is flared to 37°. Fittings are aluminum, which is lightweight with good corrosion resistance. They require a nut and a sleeve (ferrule) for each tube end. Nuts and sleeves are sold separately.
