Prevent mixing the wrong high-pressure lines—these couplings are designed to only connect with a plug or socket of the same color.

Create custom couplings to save space and snake around obstructions. These couplings let you swap in different ends to change the connection size, type, and orientation to fit your specific setup.

Also known as instant fittings, these chemical-resistant plastic fittings connect to tubing with a push. An internal gripping ring holds the tubing tight.

Create corrosion-resistant connections in food and beverage lines with just a push. Also known as instant fittings, these fittings have an internal gripping ring and an O-ring that hold tight to tubing.

Made of brass, these fittings withstand frequent washdowns in food-processing applications. They also adhere to NSF/ANSI safety standards, so they’re safe to use with food, beverages, and dairy.

Move milk, syrup, meat, and other wet-food and drink products through lines connected by cam-and-groove fittings.

Transport wet food and drink at high pressures with a hose connected by sanitary fittings.

Warm viscous food and beverages, such as syrup and honey, to keep it flowing even when the temperature drops.

Easily access lines that move highly alcoholic or acidic wet food and beverages—this hose has flanged ends that join with quick-clamp fittings.

With flanged ends that join with quick-clamp fittings, it’s easy to disconnect this hose for cleaning. It meets NSF/ANSI 61, a strict standard for drinking water systems, and is 3-A certified for its sanitary design.

Also know as pump connectors, hose is sized to specific lengths for attaching to pumps.

Made of thick, rigid nylon, this hose has excellent durability and the highest pressure rating of the retracting hose we offer.

Use this conductive hose in a grounded system to eliminate static buildup. The material is blended with carbon black, which conducts static charges away from the hose walls.

Use this hose to transfer fluid between pumps, cylinders, and other parts of your hydraulic system. It comes with female threaded fittings already attached, so it’s ready to use right out of the box.

Although only half the weight, this hose resists wear and tear 240 times better than our standard rubber hydraulic hose. It comes with female threaded fittings already attached, so it’s ready to use right out of the box.

Although only half the weight, this hose resists wear and tear 240 times better than our standard rubber hydraulic hose. The fittings come attached, so this hose is ready to connect to a male threaded fitting on one end and a female one on the other.

The fittings are also known as an instrumentation fittings. They have two sleeves (double ferrules) that bite into metal tubing for a strong seal.

Also known as an instrumentation fittings, the Yor-Lok fitting has two sleeves (double ferrules) that bite into metal tubing for a strong seal. The tube stem fitting is a short length of tubing that inserts into the end of another tube fitting.

To maintain the temperature of liquids as cold as -325° F, this hose has vacuum insulation and a reflective barrier. This prevents heat transfer in the same way a thermos does, so the exterior of the hose won’t freeze or form condensation. Thread the fittings on this hose onto a freezer or other equipment in your plant or laboratory.

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

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

The industry standard for quick-disconnect couplings, these are also known as industrial interchange couplings. Compatible with Industrial-shape plugs and sockets.

Also known as automotive couplings. Compatible with Tru-Flate-shape plugs and sockets.

Plugs and sockets are color coded by shape so you can't mix hose lines. Only plugs and sockets of the same color will fit together.

Also known as Thor couplings, these have two locking points to give you twice the gripping power of standard grip-lock couplings. They consist of a plug and a socket that connect with a quarter twist.

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.

Made of brass with a steel wing nut, these couplings are tough enough to handle occasional drops to concrete and frequent connections on dump truck, oil rigs, and other heavy duty equipment. Compared to push-to-connect couplings, these are threaded, so they're easier to connect when there's pressure in your line.

Use these couplings at pressures up to 3,000 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 Pioneer-shape plugs and sockets.
