Pair these nuts with vibration-resistant compression sleeves and fittings for a strong seal on stainless steel tubing.

Polished to at least a 15 Ra finish on the inside, these fittings have an ultra-smooth interior surface that helps prevent contamination. They are also known as ultra-high-purity 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.

Commonly used in low-pressure welding applications, these fittings connect downstream of your pressure regulator. Slide the barbed end into hose and secure with a crimp-on hose ferrule.

These couplings consist of a plug and socket that connect and disconnect quickly. Use them if you need to frequently link and unlink welding hoses, torches, and regulators. They are also known as CGA couplings.

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

Often used for loading and unloading gas tankers, these couplings are tough enough to handle frequent connections and designed to be virtually spill-free.

For installation through thick insulation, these valves have an extra-long stem.

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.

For fast installation and removal from pipelines, these valves have union fittings that disassemble into multiple pieces. All have a fluoroelastomer seal and a plastic body that can stand up to aggressive and corrosive solutions in chemical-processing applications.

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.

Made of PVDF to withstand corrosive solutions, these valves are ideal for use in chemical processing. Their luer lock fittings are quick to connect and disconnect for convenience.

Install these low-profile valves in low-clearance pipelines for natural gas, propane, and butane.

Install these valves in gas pipelines to automatically control the flow of natural gas, propane, and butane to equipment.

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

Their ball-valve design allows these valves to handle three times the flow of butterfly valves.

Use these valves to safely transfer fuel and oil.
