Made of FDA listed materials, these fittings have a single barb that creates a smooth clamping surface for extra-tight connections.

Also known as instant fittings, these connect to tubing with a push, and an internal gripping ring and O-ring hold the tubing tight. Use in applications up to 150 psi.

These quick-disconnect couplings mate with a sanitary stainless steel quick-clamp fitting for use in dairy lines.

A staple in labs, these couplings are highly versatile, fitting any luer lock plug, socket, syringe, or needle. They’re PVDF, so they resist most acids, alcohols, and organic solvents.

Fittings have a barb that grips onto tubing. Use in applications up to 120 psi.

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

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

Polished to a 20 Ra finish, these fittings have an extra-smooth interior that prevents product buildup and inhibits bacteria growth.

Also known as I-line fittings, these fittings have a male adapter that interlocks with a female adapter for more support than standard quick-clamp fittings.

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

Use with soft plastic tubing to prevent the tube from collapsing.

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.

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

Also known as ball-seat hose nipples, these fittings consist of a barbed shaft with a rounded end that sits inside a female threaded nut. When mated with a male threaded fitting, the rounded end presses tightly against the inside of the male threads for a better seal than a single-piece fitting. Once assembled, insert the barbed end into hose and secure with a clamp or a crimp-on hose ferrule.

Made of nylon, these fittings are lighter in weight than metal 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.

Also known as Chicago and universal couplings, these have identical claw-style heads and connect by being pushed together with a quarter twist.

Couplings have an identical claw-style head that connects to another twist-claw hose coupling with a quarter twist.

These couplings have a lower profile than other claw-style couplings to fit in cramped spaces. They consist of a plug and a socket that connect with a quarter twist. Also known as Bowes couplings.

Sockets accommodate five common plug shapes: Industrial, ARO, Lincoln, Tru-Flate, and European.

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

Metal cam-and-groove couplings have better durability than plastic cam-and-groove couplings.

Compatible with Lincoln-shape plugs and sockets.

Made of polypropylene, these cam-and-groove couplings are lighter in weight than metal cam-and-groove hose couplings.

Compatible with Japanese-shape plugs and sockets.

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

Made of plastic, these fittings are lighter in weight than metal barbed fittings, yet have the chemical and corrosion resistance to stand up to harsh substances. Slide the barbed end into plastic or rubber hose and secure with a clamp.

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.

Couplings are plastic, which is lighter in weight than metal 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.

Fittings meet NSF/ANSI Standard 61 for drinking (potable) water.

Couplings consist of a plug and a socket that connect and disconnect quickly. Use them if you need frequent access to a line. They are designed for coolant applications up to 200 psi. Also known as coolant-line mold couplings.

Reduce the risk of spills near electronics when connecting and disconnecting liquid cooling lines. Also known as double shut-off couplings, these couplings have a shut-off valve on both sides that stops the flow of coolant if they’re separated.

These fittings are FDA compliant, so they’re suitable for food and beverage applications and won’t impart tastes or odors to the product. Secure barbed ends into plastic or rubber hose with a clamp.

Also known as ground-joint couplings and boss couplings, these fittings are designed for high-pressure steam applications up to 600 psi. Insert the barbed end of the fitting into hose, then position the interlocking clamp over the hose and bolt into place. The clamp firmly grips your hose as it locks into the ring of the barbed end, creating a leak-tight seal.

Fittings meet NSF/ANSI Standard 61 for drinking water. Attach them to garden hose for a variety of water supply applications. They are metal for better durability than plastic garden hose fittings.

Use these barbed fittings in low-pressure steam applications up to 150 psi. Slide the barbed end into hose and secure with a clamp.

Made of ductile iron, these couplings are tough enough to handle sand, cement, and other abrasive solids and slurries. Use their cam-and-groove fittings to quickly connect and disconnect medium- to large-diameter hose lines.

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.
