1/4 in short forged refrigeration nut. Package of 1000. JB machines all of the brass fittings at the factory inch aurora, illinois using the highest level of brass consisting of 65% copper and 35% zinc. This gives our brass fittings a high tensile strength while resisting corrosion. Many import fittings use less quality brass with lower copper content and a higher failure rate. 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 5000 lb/sq-in can be handled depending on the size, material and conditions. Using a 4:1 safety factor, the following general rule is used: 3000 lb/sq-in to 1/4 in, 2000 lb/sq-in to 1/2 in and 1500 lb/sq-in to 1 in long nuts are recommended when vibration is a factor. Tubing should be double flared inch extreme applications to minimize flare thinning on over tightening. Our brass fittings generally comply with SAE, ASA, ASME and MS standards. However, when design make dimensions critical, please contact us at 800-323-0811. Heavy-duty ACR tube fittings generally conform to SAE, ASA and ARI standards for marine, hydraulic and refrigeration service. Long dry seal pipe threads minimize leakage and provide more clearance for tightening flare nuts. Shapes, elbows, tees, etc., are made from forged brass to maximize strength and eliminate cracks. Tube size listed are OD to determine nominal size, subtract 1/8 in pipe sizes listed are standard nominal pipe size and threads are to dry seal taper pipe standards. JB will provide flare fitting to SAE standard J513 whenever possible.
