Glue Devil Auto Silicone is a premium-quality, single-component sealant specifically engineered to withstand the demanding conditions of automotive environments. Formulated to resist extreme temperatures, vibrations, and common automotive fluids, it provides a permanently flexible, leak-proof seal for gaskets and joints.
Key Performance Features
- Extreme Temperature Stability: Engineered to remain stable and flexible at temperatures ranging from -50°C to +250°C (with short-term exposure up to 300°C).
- Automotive Fluid Resistance: Highly resistant to transmission fluids, gear oils, engine coolants, and water, ensuring long-term seal integrity in engine bays.
- Superior Vibration Dampening: Maintains a "rubber-like" elasticity that absorbs mechanical shocks and thermal expansion without cracking or peeling.
- Excellent Multi-Surface Adhesion: Bonds powerfully to metals (aluminum, steel, iron), glass, ceramics, and most non-porous automotive plastics.
Ideal Applications
- Gasket Maker: Perfect for creating or reinforcing gaskets on valve covers, water pumps, thermostat housings, and oil pans.
- Weather Stripping & Trim: Ideal for sealing leaking windshields, taillights, and sunroofs, as well as re-attaching loose rubber door seals.
- Electrical Insulation: Can be used to seal and protect electrical connections and wiring looms from moisture and dust.
- Manifold & Exhaust Seals: Suitable for sealing low-pressure intake manifolds and exhaust components where high heat is present.
Product Benefits
- Fast-Curing Formula: Skins over within minutes and reaches functional strength quickly, minimizing vehicle downtime.
- Non-Shrinking & Non-Cracking: Maintains its volume and flexibility over years of exposure to heat cycles.
- Easy Application: The 280ml cartridge is designed for use with a standard caulking gun, providing a consistent, professional bead.
Pro Tip: For the best "gasket-maker" results, apply a continuous bead to one surface, encircling all bolt holes. Assemble the parts while the silicone is still wet (within 10 minutes) and tighten the bolts to the manufacturer's torque specifications. For a "formed-in-place" gasket, let it skin over for 15 minutes before assembly.
