151 Stainless Steel Compression Fittings Compression Fittings 01 // Fittings Level 3 reduit / EN_Level 4 sans numero Stainless Steel Compression Fittings / Stud Fittings Component Materials Technical Characteristics These "universal" compression fittings offer excellent resistance to environmental conditions and corrosive fluids. They are pressure and temperature-resistant and are able to withstand strong vibration and water hammer. Suitable for food fluids. Ø metric: 6 to 16 mm Advantages • Excellent sealing and retention of the tube • Metallic sealing guarantees maximum service life • Connection of different types of pipes and tubes: metal, polymers, steel, rubber,... • No tube support required for rigid and semi-rigid polyamide tubing below 12 mm • Connection of several pipe diameters thanks to the Parker Legris assembly reduction system • Range of associated accessories in 316L stainless steel • Compatible Fluids: Many fluids • Working Pressure: Vacuum to 400 bar (80 bar in corrosive environments) • Working Temperature: -60°C to +250°C with metal tubing Tightening Torques DN 6 8 10 12 16 daN.m 2 3 4 6.5 9.5 Reliable performance is dependent upon the type of fluid conveyed and tubing being used. Guaranteed for use with a vacuum of 755 mm Hg (99% vacuum). Thread sealing must be guaranteed by user.

Recommended Tube Type Recommended Tube/Fitting Assembly Configurations Stainless steel tube Stainless steel tube: in cold-rolled straight lengths Coiled annealed stainless tube: reduces working pressure by 35%; do not use if there is vibration. The use of Parker Legris stainless steel compression fittings is dependant on the tube material. Tables of recommended working pressure for the different tubes are shown below. Stainless steel tube "Thin Wall" cold-drawn seamless, annealed and passivated: wall thickness tolerance +/-0.1 mm. For use with "thin wall" stainless steel tube from 6 mm to 16 mm O.D., maximum wall thickness 1 mm.
