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 Barbed Hose Fittings for Air and Water
Slide the barbed end into rubber hose and secure with the appropriate clamp or crimp-on hose ferrule.
Brass fittings are softer than other metal fittings, so they’re easier to thread together. Plain brass fittings have good corrosion resistance. Fittings with a threaded end are also known as hose nipples.
Fittings with a 45° flared end are also known as refrigeration and SAE fittings.

- Attachment Type: Use Crimp-On Hose Ferrules, except For 1/2" Hose ID: Use Band-and-Buckle Clamps
- Specifications Met: SAE J476
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. Fittings with a 45° flared end are also known as refrigeration and SAE fittings. Fittings with a female 37° and 45° flared end have a dual-angle seat that accepts both 37° and 45° flared 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.

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.

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.
Notes: Fittings are only for use with hydraulic hose.

Create or repair D.O.T. hose assemblies in the field with just a wrench and a vise, no crimper required. To install, separate the two pieces of these fittings. Screw the hose-end portion onto your hose, then thread the nipple portion into the hose-end portion. When assembled, 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 on a new one. All meet labeling and performance requirements for motor vehicle brake hose fittings.

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.
Push-to-connect sockets are easier to connect than sleeve-lock sockets. Connect by pushing the plug into the socket until you hear a click. To disconnect, slide the sleeve on the socket forward until the plug ejects.
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.

- Specifications Met: See Table
The threads on the tube end of these fittings are Class 3A or 3B and adhere to tighter tolerances than other 37° flared fittings. They are made to exact AS (formerly AN) specifications and provide a tight metal-to-metal seal on tubing that is flared to 37°. Fittings require a nut and a sleeve (ferrule) for each tube end. Nuts and sleeves are sold separately.
304 stainless steel fittings have very good corrosion resistance. 316 stainless steel fittings have excellent corrosion resistance.

- Tubing: Use with seamless steel
- Specifications Met: SAE J514
Also known as JIC (Joint Industrial Council) fittings, these provide a tight metal-to-metal seal on tubing that is flared to 37°. They require a nut and a sleeve (ferrule) for each tube end. Nuts and sleeves are sold separately. Fittings are zinc-plated steel for fair corrosion resistance.
NPTF (Dryseal) threads are compatible with NPT threads.
To prevent leaks, UN/UNF (SAE Straight) male threads have a gasket. Metric and BSPP male threads have either a gasket or a gasket and washer.
