Valveless Air Arms Male fitted with a 1/8″ BSP Blank plug.
Use with standard old style Air Arms female snap connector for quick checking of the residual pressure in your cylinder.
Can also be used if you have a Logun Mk1 Professional and your hose is fitted with the same type of connector.
To read the residual cylinder pressure, install the plug into the old style Air Arms female snap connector, close the bleed valve on the cylinder and slowly open the cylinder air control valve. The pressure inside the cylinder will be indicated on the cylinder or charging head gauge. Bleed the system after use.
Also works as a plug to keep your hose connector free of dust and debris whilst in transit or being stored.
