CRC Grey RTV Gasket Sensor Cartridge 300g

CRC Grey RTV Gasket Sensor Safe – 300g Cartridge is your go-to gasket sealer for high-torque applications and precision engine sealing. Specially formulated for reliability in modern Japanese designs, this self-forming, room-temperature vulcanising (RTV) silicone gasket maker creates a durable, oil-resistant seal without the need for traditional gasket materials or sealants.

Why this matters for your engine work:

• Sensor-safe and low odour – designed to minimize fumes and avoid corrosion around sensitive sensors and electronics.
• Intermittent service temperature up to 330°C – proven performance under hot, demanding conditions common in performance and daily drivers alike.
• Self-forming, quick-to-seal – the pure silicone rubber flows to any size and shape, sealing gaps in minutes and replacing most cut gaskets, felt, cork, paper, asbestos, or rubber gaskets without additional sealers.
• Excellent oil resistance and superior resistance to thermal cycling, vibration, cracking, and shrinking – even under frequent start/stop and temperature swings.
• Non-corrosive and low migration – ideal for long-term sealing of engine components that move, flex, or heat-cycle over time.
• Versatile adhesion – bonds effectively to a wide range of engines and housings, including rear main bearing caps, damper keyways, differential covers, timing covers, valve covers, oil pans, thermostats, water pump covers, and intake manifolds.
• No gasket sealers required – simply apply the silicone, assemble, and tighten; the material forms the seal without additional compounds.
• Not for every seal – not suitable as a head gasket seal and not intended for stove pipes or fireplaces.

Ideal use scenarios

• Rebuilding or resealing rear main bearing cap split lines, crankcase junctions, and vibration dampers on high-mileage or performance engines.
• Sealing differential covers, timing covers, and transmission pan gaskets where heat and fluids are frequent concerns.
• Restoration projects or modern Japanese engines where torque and oil exposure demand superior gasket performance.
• Oil pan corners, side cover plates, and thermostat housing seals that require a reliable, distortion-free seal across temperature cycles.
• Any application where traditional gaskets are hard to source or impractical due to unusual or custom shapes.

How to use for best results

• Ensure surfaces are clean, dry, and free from old sealant residues for optimal adhesion.
• Apply the silicone directly to one surface in a continuous bead that covers the sealing path.
• Assemble components and tighten to manufacturer specifications; no additional gasket sealers are required.
• Run the engine as directed and allow the gasket to conform; this product is designed to form a durable seal as it cures.
