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, aluminium, steel and plastic tube provided an acceptable flare could be generated with the material. Vacuum pressures of 5000 psi can be handled depending on the size, material and conditions.
