OEM RTV 1215 Silicone Gasket Maker for Subaru Engines 🚗

This is a factory-grade liquid gasket for Subaru powertrain systems. It seals oil and coolant joints on oil pans, cam carriers, timing covers, water pumps, thermostat housings, and differential covers. The neutral-cure, high-temp silicone stays flexible, resists vibration, and bonds to aluminum, steel, and cast iron. Perfect as an engine oil pan sealant or timing cover sealant, it’s a trusted Subaru sealant and RTV gasket maker. 🛠️

Why you need it ✅

Modern Subaru engines use formed-in-place gaskets. This compound fills micro-gaps, replaces paper gaskets, stops leaks, and keeps pressure correct. It prevents mess, reduces repair costs, and ensures long service life.

How it works 🔧

Apply a thin, continuous bead to clean, dry metal. It skins in 5–10 minutes, then cures with moisture to a tough elastic rubber within 24 hours. Temperature range: about −60°C to 200°C (short peaks to 250°C). Oil and coolant resistant. 🧪

What happens if it fails ⚠️

You may see oil drips, burning oil smell, low oil level or pressure, coolant seep, and noisy timing components. Excess squeeze-out can block the pickup screen, risking bearing damage.

Pro tips for best results 💡

• Degrease surfaces; no old sealant or oil film.
• Bead size 2–3 mm; join within 5–10 min; torque evenly.
• Wait 30–60 min before filling fluids; full cure in 24 h.
• Avoid over-application to prevent internal squeeze-out.
• Store the tube sealed; cap immediately after use.
