JB Industries NS4-10 Refrigeration Flare Nuts 5/8" - 10pk

5/8" SHORT FORGED REFRIGERATION NUT. PACKAGE OF 10

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 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 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: 3,000 PSI TO 1/4", 2,000 PSI TO 1/2", AND 1,500 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.
