Silicone blind gasket LF L1186217

A blind gasket creates a flexible seal without a rigid core, using only the material itself to close gaps between surfaces. Silicone is chosen for its resistance to heat and moisture, which keeps the seal intact in steam-filled environments like boiler compartments. The gasket sits between metal flanges or panels, compressing slightly when tightened to block leaks of steam, water or air.

To install, the operator places the gasket onto the clean flange surface, aligning the inner edge with the opening. Bolts or clamps are then tightened evenly around the circumference, compressing the silicone until the gap is closed. Once in place, the gasket remains in service until signs of wear or hardening appear, at which point it is peeled away and replaced.

The gasket is made of solid silicone, cut to an 8 mm outer diameter and 3 mm thickness. Its blind construction means there is no metal or plastic insert, so the entire cross-section is silicone. This design suits applications where a rigid core could interfere with sealing or where frequent removal is needed.

This gasket fits Carimali boiler and electrical parts within the Systema-Eco range, specifically model CA2201. It is listed under boiler and electrical parts in the catalogue.
