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.

Nuts for 45° Flared Fittings
for Copper and Brass Tubing

45° Flared Fittings for Copper and Brass Tubing

No sleeve is required to assemble these fittings, which makes for a faster, more convenient installation compared to 37° flared fittings. They are also known as refrigeration and SAE fittings.

Nuts for Supported 45° Flared
Fittings for Copper and Brass Tubing

Supported 45° Flared Fittings
for Copper and Brass Tubing

The flared end of the fitting nests inside the fitting body, providing extra support to the tubing. Fittings are also known as inverted 45° flared fittings.

37° Flared Fittings for Copper Tubing

Also known as JIC (Joint Industrial Council) fittings, these connect to tubing that is flared to 37°. They can handle higher pressures than 45° flared fittings.

Sleeves for 37° Flared Fittings for Copper Tubing

Nuts for 37° Flared Fittings for Copper Tubing

Tube Fittings for Stainless Steel Tubing

37° Flared Fittings for Stainless Steel Tubing

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

Nuts for 37° Flared Fittings for Stainless Steel Tubing

Sleeves for 37° Flared Fittings
for Stainless Steel Tubing

37° Flared Fittings with Thread
Sealant for Stainless Steel Tubing

The male pipe threads on these fittings have a sealant applied for extra protection against leaks.

Cleaned and Bagged 37° Flared
Fittings for Stainless Steel Tubing

Individually bagged to prevent contamination, these fittings are suitable for applications that require a high level of cleanliness.

Sleeves for Precision AN 37° Flared
Fittings for Stainless Steel Tubing

Precision AN 37° Flared Fittings
for Stainless Steel Tubing

The threads on the tube end of these fittings are Class 3A or 3B and adhere to tighter tolerances than other 37° flared fittings.

Nuts for Precision AN 37° Flared
Fittings for Stainless Steel Tubing

Vibration-Resistant Precision AN 37°
Flared Fittings for Stainless Steel Tubing

A PTFE seal on the tube end of these fittings allows for an extra-strong connection in high-vibration applications.

Yor-Lok Fittings for Stainless Steel Tubing

Use these fittings at pressures up to 9,700 psi. Also known as instrumentation fittings, they are made to tight tolerances for use in high-precision applications. They are compatible with Swagelok®, Let-Lok, and Parker A-Lok fittings.

O-Ring Face Seal Fittings for Stainless Steel Tubing

The flat face of the fitting connects to a tube adapter so you can slide the tubing and fitting sideways to disconnect in cramped spaces. They are also known zero-clearance fittings.

Tube Fittings for Steel Tubing

Sleeves for 37° Flared Fittings for Steel Tubing

Use these sleeves with a nut and fitting to provide a tight metal-to-metal seal on steel tubing that is flared to 37°.

Nuts for 37° Flared Fittings for Steel Tubing

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°.

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

Also known as JIS (Japanese Industrial Standard) fittings.

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.

Tube Fittings for Aluminum Tubing

Sleeves for 37° Flared Fittings for Aluminum Tubing

37° Flared Fittings for Aluminum Tubing

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

Nuts for 37° Flared Fittings for Aluminum Tubing

Tight-Space 37° Flared Fittings for Aluminum Tubing

The external hex bolt on these fittings allows for easy installation in cramped spaces. They are also known as banjo-style fittings and JIC (Joint Industrial Council) fittings. They provide a tight seal on tubing that is flared to 37°.

Tube Fittings for Plastic and Rubber Tubing

Plastic Push-to-Connect Tube Fittings for Chemicals

Also known as instant fittings, these chemical-resistant plastic fittings connect to tubing with a push, and an internal gripping ring and fluoroelastomer O-ring hold the tubing tight.

Tight-Seal Brass Compression
Tube Fittings for Air and Water

A built-in tube support slips inside the tubing to prevent collapsing and provides a sturdy connection for an extra-tight seal.

Push-to-Connect Tube Fittings for Drinking Water

These fittings keep their strength in moist environments and meet NSF/ANSI 61 for drinking water. Also known as instant fittings.

Stainless Steel Barbed Tube
Fittings for Food and Beverage

Made of stainless steel, these fittings are more durable than plastic barbed tube fittings for food and beverage.

Hose Fittings

Lubrication Hose Fittings

Use these two-piece fittings in grease and lubrication lines. They screw directly onto hose without the need for a separate adapter. 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.

Continuous-Swivel Threaded
Hose Fittings for Hydraulic Fluid

Also known as live swivels, these fittings swivel continuously 360° before and after installation. This not only makes installation easier, but also eliminates the twisting and kinking that can cause hose failure. 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 5,000 psi.

Metal Barbed Hose Fittings for Air and Water

Metal hose fittings have better durability than plastic barbed hose fittings.

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

Screw-On Hose Fittings for Hydraulic Fluid

These two-piece fittings screw directly onto the hose without the need for a separate adapter. 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. Use in high-pressure hydraulic applications up to 5,800 psi.

Metal Push-On Barbed Hose Fittings for Air and Water

Fittings are metal for better durability than plastic barbed hose fittings. They have sharper barbs than standard barbed hose fittings to grip push-on hose without the need for clamps or ferrules. The more you pull on the fittings, the tighter the hose will grip.

Push-On Barbed Hose Fittings for Hydraulic Fluid

Fittings have sharp barbs that grip push-on hose with no clamps or ferrules required. The more you pull on the fittings, the tighter the hose will grip. Use in low-pressure hydraulic applications up to 350 psi.
