Loctite 475374 Gasket Sealant 10.15 oz
Loctite 475374 is a white RTV silicone paste supplied in a 10.15 oz cartridge for forming gaskets on glass, metal, plastic and wood. It operates reliably from -60°F to 400°F and is rated oil resistant with non-sagging behaviour. The product suits maintenance teams and assemblers who need a room-temperature vulcanizing sealant for industrial flanges and housings.
45-minute working time and full cure
The paste provides a 45 minute working window before skinning begins, allowing alignment of large or complex parts. Full cure is achieved in one day at room temperature without heat or humidity chambers. This schedule lets crews assemble and move sub-assemblies within a single shift while the seal continues to strengthen overnight.
Temperature range and material limits
Continuous service is bounded by -60°F and 400°F; excursions beyond these points are not characterised by the manufacturer. The sealant adheres to the listed substrate families but performance on unlisted plastics, elastomers or coated metals has not been qualified. Buyers needing certified chemical resistance data or joint-movement specifications should request the technical datasheet before specifying the product.

Questions about this item
How often will the cartridge tip need replacement once the 45 min working time passes?
The RTV paste skins over after 45 minutes, so the nozzle must be cleared or swapped before each new session.
What is the first limit reached during continuous exposure near the 400 Degrees F maximum?
The sealant is rated to 400 Degrees F; sustained operation at that ceiling is the thermal limit of the cured material.
Does the cured bead stay flexible or turn brittle after all-day heat cycles?
The SI 9160 RTV formulation remains flexible across the -60 Degrees F to 400 Degrees F range, resisting embrittlement during daily thermal cycling.
