Use these heavy-duty brass fittings for high-pressure drinking water applications.

Not only do these brass fittings have the strength to handle high-pressure applications, the male threads have a sealant applied for extra protection against leaks.

Choose these fittings when you need better strength than our low-pressure brass and bronze pipe fittings.

Extreme pressures are no problem for these heavy-duty brass fittings.

Also known as Silbraze fittings.

The smooth finish inside these stainless steel quick-clamp fittings makes it easy to remove product residue.

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

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

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

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

An alternative to bolt-together fittings, these handle larger tube OD sizes and have higher vacuum ratings than quick-clamp fittings. Also known as ISO-K high-vacuum fittings, the clamps have claws that grab hold of fittings with flanged ends.

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

For high-vacuum systems with tube sizes too large for quick-clamp (KF) fittings, choose these bolt-together fittings.

Also known as luer lock couplings, these consist of a plug and socket that connect with a half turn. Use in low-pressure applications up to 30 psi.

Solder these fittings to tubing for a permanent, leak-tight connection. They are also known as sweat fittings.

Choose these metal fittings when you need better durability than our plastic push-to-connect fittings.

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

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

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

Made of nickel-plated brass, these fittings have better corrosion resistance than unplated brass fittings.

With no latch, these couplings have a compact design to fit in small spaces. They can handle pressures up to 700 psi.

A single sleeve (ferrule) compresses the tubing as you tighten the nut on these fittings, creating a strong seal. They are brass for good corrosion resistance.

Made of brass, these couplings are more durable than plastic couplings.

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

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.

Thread these caps and plugs onto fire hydrants and washdown equipment to close off the line. They have rocker lugs for easy gripping.

Attach these fittings to garden hose for a variety of water supply applications. They are metal for better durability than plastic garden hose fittings.

No need for clamps or connectors—duct and fittings have a male end that is slightly smaller than its female end for simple assembly.

Join duct and fittings with quick-release clamps for faster disassembly and cleanout than other duct systems.

Often used in tight spaces, such as in walls and ceilings, rectangular duct allows you to select larger sizes without increasing duct height.

For use with gas-fired equipment, such as boilers and furnaces, these vent pipes and fittings withstand temperatures up to 400° F. Also known as type B gas vents.

Built to withstand temperatures up to 1000° F, these vent pipes and fittings are for use with boilers, furnaces, stoves, and other equipment that is fired by coal, gas, oil, propane, or wood.

Use these caps to hold components in place and protect shaft ends.

Also known as flat-style speed nuts, these have a large surface to distribute loads better than standard and flanged external push rings.

Also known as poodle rings, these thick rings have "ears" that form a large retaining surface to withstand stronger forces than other side-mount retaining rings.

Slide these rings into place by hand with a single twist for applications with high thrust loads.

Certified by EHEDG (European Hygienic Engineering and Design Group) to meet sanitary design standards, these cap nuts fit into tight spaces to cover and seal exposed threads in your food processing facility.

Also known as flat-style speed nuts, these have large sides, so they're easy to push over threads by hand.
