This tubing has a seamless construction with no weld bead for unrestricted flow and is stronger than welded tubing.

This tubing is made to tighter tolerances than other stainless steel tubing.

Compared to other stainless steel tubing, this tubing is harder, stronger, and more durable.

This tubing withstands high pressures up to 13,700 psi. It is also known as capillary tubing.

Aluminum tubing is lightweight with good corrosion resistance and weldability.

Commonly used in marine applications, this tubing contains magnesium for extra corrosion resistance.

Seamless construction with no weld bead gives this tubing an interior with unrestricted flow. It can be flared without splitting.

A thin layer of zinc yellow-chromate gives this tubing extra corrosion resistance, making it an economical alternative to stainless steel.

Fittings have a barb that grips onto tubing. Use in applications up to 150 psi.

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.

Save time installing sleeves and nuts—these sets come oriented in the correct direction and order on a dispenser.

Use at pressures up to 1,500 psi.

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

Instead of a metal sleeve (ferrule), these fittings have a rubber sleeve that cushions tubing and absorbs vibration to maintain a tight seal, even when connected to large pumps.

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°.

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

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

Originally used on satellites, rocket propulsion systems, and even Mars rovers, these fittings will handle your most challenging industrial environments. They're designed to withstand high vibration and ultra-high vacuum without generating particles that could disrupt your operation.

Create a strong connection without heating, flaring, or soldering.

Create a strong seal on copper tubing when you couple these nuts with compression sleeves and fittings.

Also known as instrumentation fittings, these are made to tighter tolerances than standard compression fittings. They are compatible with Parker CPI fittings.

The sleeve in these fittings is rubber instead of metal, so it cushions the tubing and absorbs vibration while creating a tight seal.

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.

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

Also known as JIS (Japanese Industrial Standard) fittings.

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.

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

With the best corrosion resistance of any metal fitting we offer, these Hastelloy fittings will stand up to aggressive chemicals and are resistant to pitting and stress cracking. Also known as instrumentation fittings, they include a nut with two sleeves.

Transfer harsh chemicals while reducing vibration that could damage pumps or other equipment.

Made of stainless steel, these hose fittings are more durable than plastic barbed hose fittings and have excellent corrosion and chemical resistance. Slide the barbed end into hose and secure with a clamp.

Couplings are metal, which has better durability than plastic cam-and-groove hose couplings. They consist of a plug and a socket that connect and disconnect quickly. Use them if you need frequent access to a line. To connect, insert the plug into the socket and push the levers down.

To minimize fluid loss when connecting and disconnecting your line, these couplings have flat faces for a close fit and shut-off valves to stop the flow—they meet ISO 16028, which is an international standard for hose couplings.

Quickly connect and disconnect hose lines used with a variety of chemicals, from adhesives to isopropyl alcohol and ink. Any part of these couplings that contacts fluid is made from 316 stainless steel, C-276 Hastelloy, PTFE, or fluoroelastomer to withstand the chemicals in your line.

Access your line without twisting the hose—these unions separate into three pieces.

These CGA adapters have a male threaded end that connects to a propane tank and a male threaded end that connects to welding hose.

Use these CGA fittings to connect welding hose to pressure regulators and torches.

Designed to handle high-pressure welding applications, these CGA fittings are commonly used to connect pressure regulators to compressed gas tanks or cylinders.

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.

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.

With just a vise and a wrench, make or repair hose assemblies in the field.

Use these couplings at pressures up to 10,000 psi. The plug and socket thread together to form a stronger connection than other quick-disconnect couplings. They are compatible with High-Pressure Thread-Lock-shape plugs and sockets.

Use these couplings at pressures up to 7,200 psi. Also known as flush-face couplings, the plugs and sockets have a flat face, which allows them to mate close together, reducing fluid loss when connecting and disconnecting the line. They are compatible with International Standard ISO Minimal-Spill-shape plugs and sockets.

Add quick connection points for mechanical gauges and other diagnostic equipment to your line. These couplings are also known as test ports and diagnostic couplings.

Ideal for lines with rapid changes in pressure and flow, these couplings have threads that lock them together. They connect more securely than push-to-connect couplings, whose bearings wear out in high-impulse conditions.

Use these couplings at pressures up to 5,000 psi. They consist of a plug and socket that connect and disconnect quickly. Use them if you need frequent access to a line. They are compatible with International Standard ISO A-shape plugs and sockets.

Typically used with thick-wall and high-pressure stainless steel unthreaded pipe fittings.

Typically used with medium- to high-pressure stainless steel threaded pipe fittings.

Typically used with high-pressure galvanized iron and steel threaded pipe fittings. Also known as Schedule 160.

Typically used with thick-wall and high-pressure iron and steel unthreaded pipe fittings. Also known as Schedule 80.
