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 to make a threaded connection.

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

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.

Transfer industrial gases in temperatures up to 1500° F with this hose.

These valves automatically reduce a high inlet pressure from compressed gas tanks to a lower, stable outlet pressure.

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.

Commonly used in TIG welding where gas flow/coverage is a concern.

Designed to reduce contaminants in high-purity applications using hydrogen and methane gas, these valves have a 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.
