Arrow Union Seals are constructed of an inflatable oil-resistant (Nitrile) tube. They are used for mud suction return lines and low pressure fluid lines. When they are inflated through an automotive type air-valve, it seals the union. For effective sealing the fuel pressure should exceed the line pressure by 50 psi. Micky Arrow Union Seals make up fast and easily without close line up. This allow pipe expansion and proper alignmetn without breaking the Seal. The Seal can be broken by deflating the tube.
