How to Identify and Measure Fittings

Pipe size is an industry designation, not the actual size. View information about how to measure threaded and unthreaded pipe and pipe fittings.

Easy-Fit Barbed Hose Fittings for Air and Water

Low-profile barbs and a longer first barb allow for a smoother, easier installation than other barbed fittings. Slide the barbed end into rubber hose and secure with a clamp.

Steel fittings are stronger and more durable than other metal fittings. They should be used in noncorrosive environments. Zinc-plated steel fittings have slightly better corrosion resistance than unplated steel fittings. Aluminum fittings are lighter in weight than other metal fittings. They have good corrosion resistance. Brass fittings are softer than other metal fittings, so they’re easier to thread together. They have good corrosion resistance.

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

Fittings with a hex body can be tightened with a wrench.

Tight-Seal Barbed Hose Fittings for Air and Water

Also known as ball-seat hose nipples, these fittings consist of a barbed shaft with a rounded end that sits inside a female threaded nut. When mated with a male threaded fitting, the rounded end presses tightly against the inside of the male threads for a better seal than a single-piece fitting. Once assembled, insert the barbed end into rubber hose and secure with a clamp or a crimp-on hose ferrule. The nut swivels until tightened for easy installation. Fittings are brass for good corrosion resistance.

NPSM (National Pipe Straight Mechanical) female threads are compatible with male NPT and NPTF (Dryseal) threads.

Easy-Fit Barbed Hose Fittings for Chemicals

Low-profile barbs and a longer first barb allow for a smoother, easier installation than other barbed fittings. Slide the barbed end into rubber hose and secure with a clamp. Fittings are 316 stainless steel, which has excellent corrosion resistance to withstand a variety of chemicals.

Adapters are also known as hose nipples; they adapt a barbed end to a threaded end. Adapters with a hex body can be tightened with a wrench.

Yor-Lok Fittings for Steel Tubing

For Use With: Air, Cutting Oil, Diesel Fuel, Fuel Oil, Gasoline, Hydraulic Fluid, Mineral Oil
Tubing: Use with seamless steel
Specifications Met: See table

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. Fittings are zinc-plated steel for fair corrosion resistance. They are compatible with Swagelok®, Let-Lok, and A-Lok fittings.

Acid-Resistant Yor-Lok Fittings for Nickel Alloy Tubing

For Use With: Air, Cutting Oil, Diesel Fuel, Fuel Oil, Gasoline, Hydraulic Fluid, Hydrofluoric Acid, Mineral Oil, Salt Water, Steam, Sulfuric Acid, Water
Temperature Range: -325° to 900° F
Tubing: Use with seamless soft 400 nickel
Specifications Met: See table

Made of 400 nickel, these Monel fittings have the corrosion resistance to handle hydrofluoric and sulfuric acid. Also known as instrumentation fittings, they are made to tight tolerances for use in high-precision applications. They include a nut with two sleeves (ferrules). The sleeves bite into tubing as you tighten the nut, creating a strong, leak-tight seal. They are compatible with Swagelok®, Let-Lok, and A-Lok fittings.
