The Messi and Paoloni M&P-Silicone-Seal-S is a self-tightening silicone rubber tubular gasket designed to seal coax connectors with cables of various diameters. It provides a reliable, airtight seal without flame or heat. This versatile seal can also be used in electrical cabinets to protect connections from condensation and as a strain relief for increased tensile strength between cable and connector. The M&P-Silicone-Seal-S is factory-expanded and assembled onto a removable supporting plastic core, which shrinks to form a tight gasket when unwound. It retains its resiliency and pressure even after exposure to harsh environments, with an operating temperature range of -60℃ to 90℃ (-76°F to 194°F). To use, insert the connector inside the seal, screw the connectors together, press the seal firmly against the base of the antenna protruding connector, and pull the strip to allow the silicone rubber to shrink and settle tightly on the cable and connectors. This process does not require flame or heat, ensuring a professional and durable result.
