Description
black RTV silicone from Pacer Technology is a one-component instant gasket material for sealing metal housings, covers, fittings, and automotive-style joints without cutting a separate gasket. It cures to a tough flexible seal that stands up to oil, grease, antifreeze, transmission fluid, and repeated temperature cycling.
black RTV silicone Benefits
- Replaces cork, paper, felt, and other pre-cut gasket materials on many service and assembly jobs.
- Continuous temperature resistance from minus 75 degrees F to 400 degrees F supports engines, pumps, and general equipment housings.
- Intermittent temperature resistance to 500 degrees F helps on hotter short-duration exposure points.
- Flexible cured seal handles movement and surface variation better than rigid cut gasket material.
- Low volatile formula is listed by the product data sheet as safe for oxygen sensors.
This material fits maintenance benches, repair carts, and light production work where crews need to seal irregular flange faces or restore a gasketed joint quickly. It is commonly used on oil pans, valve covers, water pumps, thermostat housings, rear end housings, electrical connections, and similar service points where a formed-in-place gasket is easier to stage than stocked cut parts.
black RTV silicone Applications
- Forming in-place gaskets on oil pans and valve covers.
- Sealing thermostat housings, water pumps, and rear end housings.
- Protecting electrical connections and wire entries from moisture.
- Sealing doors, lights, hose connections, sunroofs, and windshield-related joints.
- General repair work where a flexible black silicone seal is preferred over a paper gasket.
