JB Industries U3-6D 406 Adapter, 3/8 x 1/2 in Nominal, Flare x Female Pipe, Brass, Domestic

• Made from forged brass to maximize strength and eliminate cracks
• Tubing should be double flared in extreme applications to minimize flare thinning on over-tightening
• Long dryseal pipe threads minimize leakage and provide more clearance for tightening flare nuts
• Long nuts are recommended when vibration is a factor
• Highest level of brass consisting of 65% copper and 35% zinc which means high-tensile strength while resisting corrosion
• 4:1 safety factor
• Heavy duty acr tube fittings generally conform to SAE, ASA and ARI standards for marine, hydraulic and refrigeration service
• Vacuum pressures of 5000 psi can be handled depending on the size, material and conditions
