Specification Brand : HARFINGTON BulletPoint1 : Size - Bulkhead Fitting Thread Size: 3/8"; Total Length: 40mm / 1.57"; Hex Diameter: 21mm / 0.83". Can pass through a maximum of 15mm thick plate. BulletPoint2 : Material - The bulkhead union fitting constructed from copper, has thermal conductivity and corrosion resistance, ensuring leak-free connections for outdoor watering systems. The nickel plating contains a significant amount of corrosion-resistant properties against atmospheric conditions, and certain acids, thus extending its service life. BulletPoint3 : Features - The internal nitrile rubber O-ring provides excellent oil and water resistance, high-pressure oil durability, and good compressive deformation. It features wear resistance, tensile strength, antistatic properties, and compatibility with polar substances like PVC, phenolic resin, and nylon, ensuring excellent airtightness. This bulkhead union maintains reliable performance under extreme conditions, with a maximum working pressure of 0.095 to 2.5 MPa. BulletPoint4 : Applications - The copper tube fitting interior can accommodate air, water, hydraulic oil, gasoline, silicone grease, silicone oil, diester-based lubricants, and glycol-based hydraulic fluids. Suitable for field for low-pressure hydraulic and pneumatic systems such as shop air, general industrial, maintenance and automotive assembly, aircraft controls, printing. BulletPoint5 : Notes - Before purchasing, please make sure the size of the fitting adapter you choose matches the pipe size. Please install it correctly during operation to ensure that it is firmly installed and the connection is tight.
