Guide to correct installation

CORRECT INSTALLATION WITH PROFESSIONAL TOOLS

INDICAZIONI PER UNA CORRETTA INSTALLAZIONE

To ensure the maximum efficiency of the gaskets, it is advisable to install them correctly, ensuring they are not damaged, and once placed in their groove, they are evenly distributed without torsion. It is essential, already in the design phase, to provide an adequate guide system, both to avoid contact between metal parts and to ensure gaskets a uniform distribution of loads.

The following are a series of points to adhere to for correct assembly:

• Analyze and consider, in the design phase, compatibility with the fluid and working cycles to select the most suitable profile and materials.
• Pay attention to clearances in the couplings, trying to keep them as tight as possible. In case of very high pressures with consequent expansions of mechanical parts, provide support rings and backup rings for the gaskets.
• Plan radii both at the bottom of the grooves and on the edges of the shoulders. Eliminate sharp edges, rounding the connecting edge with cylindrical parts. Provide wide and gentle lead-ins to better accommodate the seals.
• Adhere to recommendations regarding machining degrees and prescribed tolerances for the seats. During assembly, avoid gaskets passing over threads or holes. Prepare equipment for assembly. Do not use sharp and cutting tools that can irreparably damage the gaskets. Heat the gasket with hot oil or hot air during assembly if dimensional ratios or materials appear rigid. Grease the seals with Grease type 4 before insertion. For single-acting seals or asymmetrical ones, make sure to install them correctly with the sealing side facing the pressure. All air in the circuit must be removed before starting.
