JB Industries – JB machines all of the brass fittings at the factory in Aurora, Illinois using the highest level of brass, consisting of 65% copper and 35% zinc. This gives our brass fittings and access valves high tensile strength while resisting corrosion. Many import fittings use lower quality brass with lower copper content and higher failure rates. Our brass fittings may be used with copper, brass, aluminum, steel, and plastic tube provided an acceptable flare could be generated with the material. Vacuum pressures of 5,000 psi can be handled depending on the size, material, and conditions. Using a 4:1 safety factor, the following general rule is used: 3000 psi to 1/4″, 2000 psi to 1/2″, and 1500 psi to 1″. Long nuts are recommended when vibration is a factor.Tubing should be double flared in extreme applications to minimize flare thinning on over-tightening. Our brass fittings generaly comply with SAE, ASA, ASME, and MS standards. Long dryseal pipe threads minimize leakage and provide more clearance for
