The Compression fittings are extensively use because of it's simplicity, efficiency, low cost and easy of assembly.
1. Slide nut, Sleeve onto tubing. The thread end of the nut must face out.
2. Insert the tube into the fitting. Be sure the tube is bottomed on the fitting shoulder.
3. Assemble nut to body, and tighten the nut.
Materials-Elbow and Tees
Brass forgings-Pioneer compression fittings are made from BS-218 material. The exceptional strength of forge fittings (Over 80% stronger than castings) provides an extra safety factor.
Connectors, Unions and Nuts
Stress relieved brass bar stock-BS-249.
From - 65oF - 250oF
Fair resistance to vibration or tube movement, depending on applications involved. Use long nut for additional resistance to vibration.
Use with copper, brass and aluminium. Not recommended for steel tubing manufactured for low & medium pressure tubing connection work where excessive vibrations or tube movement is not involved. This fittings is widely used for connecting gasoline, grease, oil, water, vacuum and air lines
Working Pressure Ranges
Temperature and type of tubings used are important factors. However, the following table is good guide for proper selection at temperature 60 F.
