About Gas Regulators

For Use With: See Table
Temperature Range: -20° to 120° F

Commonly used in TIG welding where gas flow/coverage is a concern, these valves measure the gas flow rate in addition to regulating pressure. They automatically reduce a high inlet pressure from compressed gas tanks to a lower, stable outlet pressure. All have Compressed Gas Association (CGA) numbered inlet fittings for secure connections to compressed gas tanks. Choose a valve with the same CGA number as your tank and other system components. Valves have a gauge to monitor the outlet flow rate and a second gauge to monitor inlet pressure from the tank. They are single stage and reduce pressure in one step, which causes the outlet pressure to fluctuate slightly as you empty the tank.

Easy-Read Tank-Mount Pressure-Regulating
Valves with Flowmeter for Inert Gas

Male Inlet × Female Outlet With One Flowmeter

Male Inlet × Female Outlet With Two Flowmeters

Flowmeters let you see the gas flow rate from a distance. These valves automatically reduce a high inlet pressure from compressed gas tanks to a lower, stable outlet pressure. All have Compressed Gas Association (CGA) numbered inlet fittings for secure connections to compressed gas tanks. Choose a valve with the same CGA number as your tank and other system components. They have a gauge for monitoring inlet pressure from the tank.

Single-stage valves reduce pressure in one step, which causes the outlet pressure to fluctuate slightly as you empty the tank. They’re best for applications where a constant outlet pressure isn’t critical.

Two-stage valves progressively reduce pressure over two steps for more consistent outlet pressure at all times. They’re often used in applications that require a constant outlet pressure regardless of the tank level.

Valves with one flowmeter are for one piece of equipment on a tank. The flowmeter has a single scale.

Valve with two flowmeters lets you simultaneously run two pieces of equipment from one tank. Both flowmeters have a dual scale.

Adapters (sold separately) change 5/8"-18 outlets to 9/16"-18 male connections, and vice versa.

Tank-Mount Pressure-Regulating Valves for Air and Inert Gas

For Use With: See Table
Temperature Range: -20° to 120° F

These valves automatically reduce a high inlet pressure from compressed gas tanks to a lower, stable outlet pressure. All have Compressed Gas Association (CGA) numbered inlet fittings for secure connections to compressed gas tanks. Choose a valve with the same CGA number as your tank and other system components. Valves have a gauge to monitor outlet pressure and a gauge to monitor inlet pressure from the tank.

Choose a valve with a maximum outlet pressure that’s approximately twice your application’s normal operating pressure. Your operating pressure should never exceed 75% of the valve’s maximum outlet pressure.

Valves with a brass body have a longer service life than valves with a brass and steel body.

Valves with a stainless steel diaphragm can withstand harsh environments.

Valves with flared tube outlet fittings form a tight seal on metal tubing.

Tank-Mount High-Pressure-Regulating Valves for Air and Inert Gas

For Use With: See Table
Temperature Range: -20° to 120° F

Often used for pressure-vessel testing and other high-pressure applications, these valves can handle at least seven times the outlet pressure of standard tank-mount pressure-regulating valves. They automatically reduce a high inlet pressure from compressed gas tanks to a lower, stable outlet pressure. All have Compressed Gas Association (CGA) numbered inlet fittings for secure connections to compressed gas tanks. Choose a valve with the same CGA number as your tank and other system components. Outlet fittings are Swagelok® for a leak-free seal around hard metal tubing in high-pressure lines. Also known as instrumentation fittings, Swagelok® fittings are compatible with Parker A-Lok, Gyrolok, Bilok, and Tylok fittings. Valves have a gauge to monitor outlet pressure and a gauge to monitor inlet pressure from the tank. They are single stage and reduce pressure in one step, which causes the outlet pressure to fluctuate slightly as you empty the tank.

High-Purity Tank-Mount Pressure-Regulating Valves for Inert Gas

For Use With: See Table
Temperature Range: -20° to 120° F

Reduce contaminants in research sample systems, emission monitoring systems, chromatography, and other high-purity applications that use argon, helium, nitrogen, or carbon dioxide. These valves have a 316 stainless steel and brass body with a smooth finish to reduce dust collection and internal components designed to protect the seal and diaphragm from contamination. They automatically reduce a high inlet pressure from compressed gas tanks to a lower, stable outlet pressure. All have Compressed Gas Association (CGA) numbered inlet fittings for secure connections to compressed gas tanks. Choose a valve with the same CGA number as your tank and other system components. Outlet fittings are Swagelok® for a leak-free seal around hard metal tubing in high-pressure lines. Also known as instrumentation fittings, Swagelok® fittings are compatible with Parker A-Lok, Gyrolok, Bilok, and Tylok fittings. Valves have a gauge to monitor outlet pressure and a gauge to monitor inlet pressure from the tank.

Chrome-plated valves add a layer of corrosion resistance.

Tank-Mount Pressure-Regulating Valves for Moisture Removal

For Use With: Nitrogen
Temperature Range: 32° to 120° F

Designed for nitrogen gas purging in air conditioning, refrigeration, and plumbing systems, these valves automatically reduce a high inlet pressure to a lower, stable outlet pressure. They have Compressed Gas Association (CGA) numbered inlet fittings for secure connections to compressed gas tanks. Choose a valve with the same CGA number as your tank and other system components. Valves have 45° flared tube outlet fittings for a tight seal on metal tubing. They come with a gauge to monitor inlet pressure from the tank.

High-Pressure Nipples for Compressed Gas

Commonly used in high-pressure welding applications, these nipples connect your tank to the inlet of a pressure regulator. One side has a threaded pipe end and the other side has a rounded end that sits inside a threaded nut (sold separately) so you can make a threaded connection.

Brass nipples have good corrosion resistance and are softer than 316 stainless steel nipples, so they're easier to thread together. Chrome-plated brass nipples have better corrosion and wear resistance than unplated brass nipples and have a bright, shiny appearance.

Nipples that tighten by hand should be paired with a nut with a plastic grip.

High-Pressure Threaded Fittings for Compressed Gas

Designed to handle high-pressure welding applications, these fittings are commonly used to connect pressure regulators to compressed gas tanks or cylinders. Fittings are also known as CGA (Compressed Gas Association) fittings. They are brass for good corrosion resistance.

Fittings with left-hand threads are identified with a notch in the nut.

Note: Fittings have a CGA number that corresponds to a specific type of gas. Choose a fitting with the same CGA number as your tank and other system components.
