Hi-Temp Engine Sealant Oil Resistant No-Gasket Adhesive 50/85g

Hi-Temp Engine Sealant – Oil Resistant No-Gasket Adhesive for Car, Motorcycle & More

Keep your engine running leak-free with this high-temperature, oil-resistant sealant. Whether you're tackling an oil pan, valve cover, timing cover, or any other engine gasket surface, this versatile no-gasket adhesive creates a durable, flexible seal that resists heat, oil, and vibration. Available in both 50g and 85g sizes to suit DIY mechanics and professional workshops alike.

Key Features

• High-Temperature Resistance: Formulated to withstand extreme engine heat, helping extend the life of your vehicle components.
• Oil & Fluid Resistant: Creates a reliable barrier against engine oil, coolant, and other automotive fluids — preventing leaks and seepage.
• No-Gasket Formula: Works as a formed-in-place gasket (FIPG) replacement or can be used alongside existing gaskets for added sealing power.
• Flexible Rubber Compound: Cures via oxidation hardening to form a tough yet flexible rubber seal that absorbs vibration without cracking.
• Low Odour: Pleasant to work with in enclosed spaces like garages and workshops.
• Long Shelf Life: 3-year shelf life so you always have it ready when you need it.
• Wide Application: Ideal for car maintenance, oil leakage prevention, motorcycles, and general automotive engine sealing tasks.
• Two Sizes Available: Choose from 50g for quick repairs or 85g for larger or multiple jobs.

Frequently Asked Questions

Q: What surfaces is this high-temperature engine sealant suitable for?

A: This automotive engine sealant is designed for use on metal engine surfaces including oil pans, valve covers, timing covers, intake manifolds, and other gasket mating surfaces on cars, motorcycles, and other motor vehicles. It bonds and seals wherever oil and fluid leakage is a concern.

Q: How long does the sealant take to cure?

A: The sealant cures through oxidation hardening once exposed to air. Initial skin-over typically occurs within 15–30 minutes; allow a full cure of several hours before exposing the seal to engine fluids and heat. For best results, follow the application instructions and avoid running the engine until a full cure has been achieved.

Q: Can I use this sealant as a complete gasket replacement?

A: Yes — this product functions as a formed-in-place gasket (FIPG/no-gasket sealant), meaning it can be used on its own in place of a traditional cut gasket, or applied as a supplement on top of an existing gasket for additional sealing strength. It is especially useful in situations where a pre-cut gasket is unavailable.

Q: Is the 50g or 85g size better for my needs?

A: The 50g tube is perfect for single or minor repair jobs, such as resealing a valve cover or small leak. The 85g tube is better suited to larger surfaces, multiple applications, or if you want extra on hand for future maintenance. Both provide the same high-temperature, oil-resistant formula.
