Features
 
316 stainless steel is standard material. Other materials are available upon request.
Straight fittings are manufactured from quality bar stock. Shaped fittings are made from forgings.
Quality machining of all ports ensures consistent welding.
 Radius junction design with elbows provides a smooth flow path.
All fittings are cleaned to remove oil, grease, and loose particles.
 Every fitting is stamped with size, material, and heat code.
Technical Data
Sizes range from 1/8" to 1" and 6 mm to 38 mm.
Working Temperatures:

 
Material Minimum Temperature Maximum Temperature
316 SS -325oF (-198oC) 1000oF (538oC)
316L SS -325oF (-198oC) 850oF (454oC)
Working Pressure:
1. Catalog working pressures shown are based on ANSI/ASME B31.3 at ambient temperature, to determine working pressures in accordance with ANSI/ASME B31.1 multiply catalog working pressures shown by 0.94.
2. Use the allowable working pressure at ambient temperature to multiply the elevated temperature factors to get the working pressure at elevated temperature. To know the elevated temperature factor, please refer to the related information of VFK
6 Series Tube Fittings.

Ordering Information
Add the material designator as a prefix to the primary ordering number to get the complete ordering number. Example:
1. Male connector with 1/4" fractional tube butt weld, 1/4 NPT thread and 316 stainless steel material, the complete ordering number is SS21-TB4N4.
2. Male elbow with 1/4" fractional tube socket weld, 1/4 NPT thread and 316L stainless steel material, the complete ordering number is 6L22-TS4N4.
To order fittings with special cleaning and packaging, follow the ASTM G93 C standard and add -V2 as a suffix to the ordering number. For example, SS21-TB4N4-V2.

 Using the same materials to weld will ensure the same expansion coefficients and suitable welding.
Tungsten Inert Gas Welding (TIG) is recommended.
