Inox
Procedure for assembling spherical fittings of type D Inox.
Place the male fitting against the gasket housed inside the female fitting.
Place the short hook in the outer ring seat.
While holding the short hook in place, in the outer ring seat, open the handle for the long hook to sit in the outer ring seat.
Finally, once you have ensured that the male fitting is fairly aligned and does not run the risk of damaging the gasket, you close the handle to tighten the complete fitting.

Technical advice

For total security against accidental opening, the cotter pin should be inserted into the appropriate holes in the handle and long hook.

For new fittings, in order to close them more easily, it is recommended (especially for larger sizes) to lightly lubricate the seal with a suitable lubricant.

Materials

Stainless steel fittings consist of X5CrNi18-10 UNI EN 10088 (AISI304).
