Typically used with medium-pressure galvanized iron and steel threaded pipe fittings. Also known as Schedule 80.

Typically used with extreme-pressure iron and steel threaded pipe fittings. Also known as Schedule XXH.

Bolt these flanges to another same-size flange with a gasket to create an access point within a pipe line. They are also known as Silbraze flanges.

Build a compressed air system in half the time it would take to build a copper or steel system.

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.

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.

Bolt these fittings onto your ultra-high-vacuum chamber to transfer liquids and gases inside. Also known as feedthroughs, they come assembled with a flanged (CF) fitting, metal tubing, and two Yor-Lok tube fittings.

Also known as CGA nuts, these are designed for low-pressure welding applications downstream of your pressure regulator. Attach them to barbed hose fittings for compressed gas to make a threaded connection to torches or pressure regulators.

These nuts attach to high-pressure nipples for compressed gas so you can connect your tank to the inlet of a pressure regulator.

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

Compression fittings bite down on the outside of hard metal tubing for a secure connection.

Press these orifices into machined holes in connectors, manifolds, and other custom parts.

Access the handle of these valves while protecting your line behind an instrument panel. They have threads and a hex nut below the handle for panel mounting.

The most chemical-resistant threaded valves we offer, these have a PTFE seal and an alloy body that can withstand extremely aggressive and corrosive chemicals, such as methyl ethyl ketone and toluene.

Barbs grip onto tubing, providing a secure hold. To withstand aggressive and corrosive solutions in chemical-processing applications, these valves have a plastic body and a chemical-resistant seal.

Insert tubing into the fittings on these valves—no heat, solder, or flux required. To withstand aggressive and corrosive solutions, they have a chemical-resistant fluoroelastomer seal and a plastic body.

Designed to withstand extremely cold liquid gases, these valves are ideal for liquid nitrogen cooling systems and liquified gas storage. Insert unthreaded pipe into the socket ends and weld to create a permanent, leak-tight connection.

Built to handle the extreme cold of liquid gases, these bronze valves are ideal for liquid carbon dioxide carbonation systems, liquid nitrogen coolant systems, and other cryogenic applications.

Built to withstand the extreme cold of liquid nitrogen and liquid oxygen, these valves are cleaned and bagged for high-purity applications.

Use air pressure to automatically control the flow of liquids in sanitary environments, such as food and beverage processing plants.

Also known as diaphragm valves, these have a diaphragm that can handle dirty liquid, slurries, and abrasive media without damage.
