Description
When you’re knee-deep in an engine rebuild or chasing down a persistent oil leak, you need a sealant that won’t quit on you. This black RTV silicone is the go-to choice for sealing everything from oil pans to valve covers—it cures to a flexible, oil-resistant seal that handles the heat and vibration your tractor dishes out every day.
What You’re Getting
- Professional-grade silicone that forms gaskets in place—no more hunting for the right paper gasket
- Oil and coolant resistant formula that won’t break down when exposed to fluids
- Stays flexible after curing so it moves with your engine instead of cracking
- Temperature range that handles everything from cold morning starts to hard-working summer days
- 3-ounce tube gives you plenty for multiple jobs without waste
Built for Real Farm Work
This RTV works great on diesel and gas engines across all your equipment—tractors, combines, balers, and anything else with an engine that needs sealing. Whether you’re replacing a valve cover gasket on your utility tractor or sealing an oil pan on the big machine, this stuff forms a custom seal that fits perfectly every time.
Made to Last
Farm engines run hard and hot, and cheap sealants just don’t cut it. This Permatex formula is built to handle the constant temperature cycling and vibration that would make other sealants fail. Once it cures, it stays put and keeps doing its job season after season.
Good to Know
Clean the surfaces with brake cleaner or degreaser before applying—oil residue will prevent a good bond. Apply a continuous bead about 1/8 inch thick and assemble parts within 20 minutes. It’ll skin over quickly but takes about 24 hours to fully cure, so let it sit overnight before adding fluids.
