Couplings consist of a plug and a socket that connect quickly. Use them if you need frequent access to a line. They are designed for low-pressure steam applications up to 300 psi.

Use with interlocking-clamp hose fittings to replace a damaged clamp. They consist of two halves held together by nuts and bolts.

These couplings are compatible with International Standard ISO Series B-shape plugs and sockets. They are FDA compliant, so they’re suitable for food and beverage applications and won’t impart tastes or odors to the product. They consist of a plug and a socket that connect and disconnect quickly so you can frequently access your line. Use at pressures up to 220 psi.

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.

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.

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

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

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

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.

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.

Connect to high-vacuum pumps to route exhaust fumes out of your work area. Also known as roughing hose.

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

Designed for ultra-clean environments, these manifolds are cleaned, dried, and vacuum sealed in plastic to prevent dirt and moisture from contaminating the inside. Use them to distribute air or fluid to multiple locations from a single supply source. Also known as headers.

A great solution when space is at a premium, these manifolds are less than an inch in height, yet allow you to supply up to 12 lines from one distribution point.

Use these manifolds with molding equipment to circulate hot and cold water through your line. They have a red side for hot water and a blue side for cold water.

Connect two pipes that are up to 100 feet apart—cut the connector to the length you need and attach a clamp to each end.
