3/4 in. Tube O.D. Tube Union - 316 Stainless Steel Double Ferrule Tube Fitting

• Compression, Instrumentation, Vacuum, Gas, Cryogenic, High pressure and Temperature Service.
• These tube fittings are designed using industrial codes and specifications with additional cutting edge engineering on swaging action and sealing integrity.
• They also provide excellent leak-fee sealing on high pressure gas, vacuum, impulse, thermal shock, heavy vibration and many other stringent applications.
• All tube fittings are double ferrule and consist of a body, front ferrule, back ferrule and nut.
• Stainless steel bar stock conforms to ASTM A276, ASTM 479, ASME SA479 and JIS GA 303.
• Stainless steel forged fittings conform to ASTM A182, ASME SA 182 and JIS G3214.
• The pressure rating of a BFO Tube Fitting is rated to the working pressure of the connective tubing.

Connect fractional tube - all tube end connections are the same size.

Double Ferrule

Many tube fittings have a male or female pipe end. These ends sometimes have a lower pressure rating than the pressure rating of the tube fitting end. The ratings shown above are based on ASME B31.3-1999.
Female pipe ends have lower ratings than male pipe end in a given size due to the inner and outer diameters of the female threads being larger than those of the male pipe ends.
