Mount these valves onto compressed gas tanks. Also known as Schrader valves—which are typically used with compressed air—they have an internal spring that holds the valve shut when you depress the pin to add, remove, or check the pressure of compressed gas. Made of brass, these valves thread onto nuts more easily than valves made of harder metal. They also have good corrosion resistance. Valves have a thread cap to protect the stem from accidental gas release.

Valves for use with butane are commonly used on torches. They’re nickel plated for extra corrosion resistance.

Valves for use with nitrogen are often used in central heating systems.

Add air and hydraulic fluid to high-pressure struts, tanks, and hydraulic accumulators—these fill valves withstand pressures up to 5,000 psi. They meet MIL-PRF-6164, a military spec for high-pressure pneumatic valves used on aircrafts. Their stainless steel body resists rust in wet environments.

Screw a coupler (not included) onto these valves to open them and let air flow in.

Valves with locking wire resist vibration to stay securely fastened.

Tap into refrigerant lines to drain and fill your system. These valves are self-piercing and can be installed without drilling a hole into the line. A valve cap is included.

Style 2 has a removable core to provide unobstructed flow for your refrigerant once the core is removed.

Replacement cores and core kits are sold separately. The kits include a core remover with four valve cores.

For hard-to-reach spaces, these valves are longer than standard air conditioner service valves. They tap into refrigerant lines to drain and fill your system. All have a removable core to provide unobstructed flow for your refrigerant once the core is removed. A valve cap is included.

Replacement cores and core kits are sold separately. The kits include a core remover with four valve cores.
