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.

Pipe and Pipe Fittings

Compact Extreme-Pressure
Steel Threaded Pipe Fittings

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

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

testString

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

High-Pressure Iron and Steel Threaded Pipe Fittings

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

testString

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

Right-Angle Flow Rectangular Manifolds

testString

Distribute air or fluid to multiple locations from a single supply source with these manifolds. They are also known as headers.

Straight-Flow Rectangular Manifolds

Unlike other manifolds, which have an inlet on either end, these have one inlet on the opposite side from the outlets. This design allows air or fluid to follow a straight path, improving flow through your system. Also known as headers.

Tube Fittings for Steel Tubing

37° Flared Fittings for Steel Tubing

testString

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

Tight-Space 37° Flared Fittings for Steel Tubing

Tight-Space 37° Flared Fittings for Steel Tubing

The external hex bolt on these fittings allows for easy installation in cramped spaces.

30° Flared Fittings for Steel Tubing

testString

Also known as JIS (Japanese Industrial Standard) fittings.

Compression Fittings for Steel Tubing

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

High-Pressure Compression Fittings for Steel Tubing

testString

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.

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.

O-Ring Face Seal Fittings for Steel Tubing

A tube adapter sits flush against the flat face of the fitting so you can slide the steel tubing and fitting sideways to disconnect in cramped spaces. Also known as zero-clearance fittings.

Inline Hydraulic Valves

Flow-Regulating Inline Hydraulic Valves

Maintain a fixed flow rate even if pressure changes in the system.

Backflow-Prevention Inline Hydraulic Valves

testString

Also known as check valves, these open to allow flow in one direction and close when flow stops or reverses.
