About Measuring Fittings

Measure the threaded ends of your fittings to identify their pipe size, thread size, schedule, and thread type. Then, find compatible components.

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.Aluminum fittings are lighter in weight than other metal fittings. They have good corrosion resistance.

Fittings with a threaded end are also known as hose nipples.

Metric, UN/UNF (SAE Straight), and BSPP male threads with gasket protect against leaks.

37° Flared Fittings for Steel Tubing

For Use With: Air, Cutting Oil, Fuel Oil, Hydraulic Fluid, Mineral Oil
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.

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.

Sleeves

Temperature Range: -60° to 400° F

Use these sleeves with a nut and fitting to provide a tight metal-to-metal seal on steel tubing that is flared to 37°. Sleeves are zinc-plated steel for fair corrosion resistance. They are also known as ferrules.

Inch × metric sleeve adapters convert the fitting from inch to metric.

Low-Profile Hex Manifolds

When you’re short on vertical space, these manifolds are a good fit—they have outlets on the side instead of on top, so they have a lower profile than rectangular manifolds. Use them to distribute air, water, or hydraulic fluid to five locations from a single supply source. Manifolds have mounting holes, so you can mount from the top.

Anodized aluminum manifolds are the industry standard for the most common types of applications. They are lighter in weight than other metal manifolds and have good corrosion resistance. These manifolds are anodized for a black finish.

316 stainless steel manifolds have excellent corrosion resistance and can handle fuel, gasoline, coolant and other harsh substances.
