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.

Low-Pressure Iron and Steel Threaded Pipe Fittings

Use these fittings for low-pressure applications in noncorrosive environments.

Low-Pressure Cast Iron Threaded Pipe Fittings

Low-Pressure Galvanized Iron
and Steel Threaded Pipe Fittings

The galvanized finish on these fittings provides fair corrosion resistance. Fittings are for use in low-pressure applications.

Low-Pressure Galvanized Steel
Threaded Pipe Fittings with Sealant

The male threads on these fittings have a sealant applied for extra leak protection.

Compact Extreme-Pressure
Steel Threaded Pipe Fittings

These fittings are strong enough to handle extreme pressures, yet small enough to fit into cramped spaces.

Compact Precision Extreme-Pressure
Steel Threaded Pipe Fittings

Made to tighter tolerances than other steel pipe fittings, these are also known as instrumentation fittings.

Extreme-Pressure Steel Threaded Pipe Fittings

The strongest steel fittings we offer, these can withstand extreme-pressure applications.

High-Pressure Iron and Steel Threaded Pipe Fittings

These fittings can stand up to high-pressure applications. Use them in noncorrosive environments.

High-Pressure Galvanized Steel Threaded Pipe Fittings

A galvanized finish gives these fittings better corrosion resistance than our plain steel high-pressure fittings. Also known as Pressure Class 3000 fittings.

Medium-Pressure Iron and Steel Threaded Pipe Fittings

For use in noncorrosive environments, these fittings have better strength than our low-pressure iron and steel pipe fittings.

Medium-Pressure Galvanized Iron
and Steel Threaded Pipe Fittings

A galvanized finish gives these fittings fair corrosion resistance. They have the strength to handle medium-pressure applications.

Iron and Steel Unthreaded Pipe and Pipe Fittings

Low-Pressure Steel Unthreaded Pipe Flanges

Bolt two flanges of the same size together with a gasket to create an access point in a pipe line.

Low-Pressure Press-Connect
Steel Unthreaded Pipe Fittings

Crimp these fittings onto steel pipe to form a tightly sealed connection that’s faster than threading or welding and doesn’t require heat.

Standard-Wall Butt-Weld Steel Unthreaded Pipe Fittings

Butt-weld fittings allow for a smooth, flush connection that provides maximum flow.

Extreme-Pressure Socket-Connect
Steel Unthreaded Pipe Fittings

Also known as Pressure Class 6000 fittings, these heavy duty forged fittings are the strongest steel fittings we offer.

Thick-Wall Butt-Weld Steel Unthreaded Pipe Fittings

Butt-weld fittings allow for a smooth, flush connection that provides maximum flow.

Extreme-Pressure Steel Unthreaded Pipe Flanges

For excellent strength in extreme-pressure applications, choose these heavy duty Pressure Class 1500 flanges.

High-Pressure Steel Unthreaded SAE Pipe Flanges

Also known as Code 61 SAE hydraulic flanges.

High-Pressure Socket-Connect
Steel Unthreaded Pipe Fittings

Socket-connect fittings are easier to weld than butt-weld fittings because the fitting doesn't need to align perfectly to the pipe. Slide the pipe into the socket and weld.

High-Pressure Steel Unthreaded Pipe Flanges

Forged for extra strength, these heavy duty unthreaded flanges can withstand high-pressure applications.

Low-Pressure Clamp-On Connectors for Drain, Waste, and Vent

Tube Fittings for Steel Tubing

30° Flared Fittings for Steel Tubing

Also known as JIS (Japanese Industrial Standard) fittings.

37° Flared Fittings for Steel Tubing

Also known as JIC (Joint Industrial Council) fittings, these provide a tight metal-to-metal seal on steel tubing that is flared to 37°.

Yor-Lok Fittings for Steel Tubing

These fittings have two sleeves for extra gripping power. They bite into steel tubing as you tighten the nut to form a strong seal.

High-Pressure Compression Fittings for Steel Tubing

Thicker walls make these fittings—sometimes called flareless or bite fittings—withstand about twice as much pressure as standard compression fittings, so they’re good for hydraulic power applications.

Compression Fittings for Steel Tubing

A single sleeve (ferrule) bites into tubing as you tighten the nut, creating a strong seal.

Hose Fittings

Industrial Quick-Disconnect Hose
Coupling Size-Identification Kits

Kits contain Industrial quick-disconnect plugs in four coupling sizes so you can determine the size of your couplings without needing to measure.

Threaded Hose Fittings for Hydraulic Fluid

Fittings are threaded on both ends so you can connect them directly to a threaded hose or to pumps, cylinders, and other equipment in your hydraulic system. Use in high-pressure applications up to 6,000 psi

Caps and Plugs

Metal Round Caps

More durable than plastic caps, these provide the most protection from abrasion and impact.

Threaded Standoff Caps

Give open-ended standoffs a finished look and protect them from dirt and debris.

Fixture Plate Chip Plugs

Keep chips and shavings from clogging or damaging unused holes on fixture plates in milling machines.

Grease Fittings

Inject lubricant into motors, bearings, engine blocks, and all kinds of machinery.

Leakproof Grease Fittings

Keep thin grease from leaking out—the check valve on these fittings has a Buna-N seat that creates a tighter seal than check valves on other grease fittings.

Grease Fitting Assortments

Assortments contain straight, 45° elbow, and 90° elbow fittings.

Flow-Stop Grease Fittings

Prevent damage to bearing seals caused by over-lubrication—these fittings automatically stop grease flow when pressure is within the shut-off range.

Button-Head Grease Fittings

Often used on earth movers, mining equipment, and other heavy machinery, these fittings have a T-shaped top that holds the dispensing tip in place so it won't pop off when adding grease.

Flush-Style Grease Fittings

Use these fittings in tight spaces where protruding fittings won't work.

Self-Tapping Grease Fittings for Unthreaded Holes

Ensure a secure fit in unthreaded holes—these fittings cut threads as they’re installed. They're also known as hydraulic grease fittings.

Flush-Style Grease Fittings for Unthreaded Holes

Use these fittings in tight spaces where protruding fittings won't work. Drive them into unthreaded holes.

Grease Fitting Adapters

When the size or thread type of a fitting doesn't match an existing opening, use these adapters to make the connection.

Grease Fittings for Unthreaded Holes

Drive these fittings into unthreaded holes. They're also known as hydraulic grease fittings.

Self-Tapping Flush-Style Grease
Fittings for Unthreaded Holes

Ensure a secure fit in unthreaded holes—these fittings cut threads as they’re installed. Use these fittings in tight spaces where protruding fittings won't work.

Grease Fitting Tools for Unthreaded Holes

Tap these tools once or twice with a hammer to install fittings.

Grease Fitting Cleaning Tools

Fill these tools with light oil, then tap with a hammer to open clogged fittings.

Grease Fitting Tools for Threaded Holes

Remove worn fittings and repair threaded holes.

Grease Fitting Manifolds

Lubricate multiple points from a single location.

Oil Fittings

Install these fittings into threaded holes.

Oil Fittings for Unthreaded Holes

Drive these fittings into unthreaded holes.

Push-On Retaining Caps

Use these caps to hold components in place and protect shaft ends.
