## Overview

Wynn's Black Gasket Maker is a high-performance polysiloxane sealant engineered for automotive and industrial use. It withstands extreme temperatures from -40°C to 260°C, resists oils, fluids, and toxic gases, and replaces traditional gaskets with a flexible, durable bond. Safe for catalytic converters and electronic sensors, it ensures leak-proof, long-lasting seals on engine components and beyond.

## Description

Specially designed for high-performance sealing, Wynn’s High-Temperature Flexible Gasket Maker Sealant provides a durable and adaptable solution for various automotive and industrial applications. This advanced polysiloxane-based formula is engineered to withstand extreme temperatures, offering continuous resistance from as low as -40°C up to 232°C, with intermittent tolerance reaching 260°C. Its flexibility and stability ensure long-lasting performance, even under challenging conditions where heat, cold, or mechanical stress is a factor. Unlike other gasket materials, this sealant creates a fully customised bond directly on the surface, eliminating the need for pre-cut gaskets that may degrade over time. The easy-to-use pressure cartridge system allows for rapid and precise application, forming a watertight and airtight seal that effectively prevents leaks and contamination. It provides outstanding resistance to oils, transmission fluids, antifreeze, grease, water, smoke, and hot toxic gases, making it an essential solution for engine maintenance and repair. Designed to be safe for modern vehicles, it does not harm catalytic converters or electronic sensors, ensuring compatibility with contemporary automotive systems. This makes it an ideal choice for use in engines, transmissions, crankcases, water pumps, and other essential components where reliable sealing is required. Whether for professional mechanics or DIY repairs, Wynn’s High-Temperature Flexible Sealant delivers long-term reliability, reducing the risk of leaks and enhancing overall component performance. With superior durability, chemical resistance, and high-temperature tolerance, this high-quality sealant is the perfect choice for those seeking an efficient and long-lasting alternative to traditional gaskets. It provides a strong and flexible bond that remains secure under extreme conditions, making it an indispensable tool for various applications. From routine maintenance to demanding repair work, Wynn’s High-Temperature Flexible Sealant ensures optimal performance and protection for critical engine and mechanical components.

Review: Excellent product - Never used a wet gasket sealer and was very unsure about the process, used to seal the timing cover on a 2015 vivaro, watched videos on YouTube and was very careful on cleaning the mating surfaces with degreaser and brake cleaner Application is very easy as the can is pressurised and easily controllable, now a few months down the line and the gasket is still holding strong with no leaks. When dry, feels like a normal semi pliable rubber gasket, very impressed and if I ever need to, I will use again
Review: Does exactly what it’s supposed to. Great - Great product. Very pleased

## Features

- Pressurised container: May burst if heated.
- ✅ HIGH-TEMPERATURE RESISTANT SEALANT: Specially designed to withstand extreme temperatures, this polysiloxane-based material remains effective in both low and high thermal conditions. It endures continuous exposure to temperatures as low as -40°C, ensuring flexibility and stability in cold environments. Simultaneously, it provides excellent heat resistance, tolerating up to 232°C continuously and 260°C intermittently. This makes it a highly reliable solution for use in demanding automotive and industrial applications where exposure to extreme heat and cold is a concern.
- ✅ EXCELLENT RESISTANCE TO OILS, FLUIDS, AND TOXIC GASES: Designed for durability and high performance, this flexible sealant effectively resists a variety of harsh substances. It maintains a secure seal against oils, transmission fluids, antifreeze, grease, and water, preventing leaks and ensuring proper functionality of mechanical components. Additionally, it withstands exposure to smoke and hot toxic gases, making it suitable for automotive engines and exhaust systems where these elements are present. This superior resistance ensures reliable operation under demanding conditions, reducing the risk of damage caused by fluid contamination or environmental exposure.
- ✅ REPLACES TRADITIONAL GASKETS: Engineered to serve as a highly efficient alternative to conventional gaskets, this product eliminates the need for other materials. By forming a strong, flexible, and durable bond, it creates customised seals directly on the required surfaces. The application process is simplified, reducing installation time while improving reliability. Unlike traditional gaskets that may degrade, crack, or require frequent replacement, this advanced sealant offers a superior long-term solution, adapting perfectly to the shape and needs of each component without the limitations of pre-cut gaskets.
- ✅ SAFE FOR CATALYTIC CONVERTERS AND ELECTRONIC SENSORS: The innovative formulation ensures that it does not damage catalytic converters or interfere with sensitive electronic sensors, making it safe for modern vehicle systems. Unlike some sealants that can emit harmful substances affecting emissions control devices, this polysiloxane-based compound remains chemically stable and non-reactive with vehicle components. This makes it an excellent choice for use in engines, transmissions, and other automotive applications where maintaining system integrity is essential.
- ✅ IDEAL FOR ENGINE COMPONENTS AND VARIOUS APPLICATIONS: Perfect for use in a wide range of applications, including engine components such as cylinder-head covers, oil crankcases, transmissions, water pumps, and thermostats. Its ability to create strong and flexible seals makes it ideal for both automotive and industrial settings. Whether used for routine maintenance, repair work, or performance upgrades, this high-performance sealant ensures a reliable and long-lasting solution.

## Questions & Answers

**Q: When fitting a rocker cover do you apply to both surfaces or just the head.**
A: We use it regularly on our tractor puller which has the rocker cover off every month or so during the summer. We find it best to put the silicon onto the decreased rocker cover then let it go off for at least an hour then attach rocker cover  to a greased head, this way we can remove multiple times without fuss of peeling and replacing silicon as it stays firmly adhered to rocker cover . If you glue it down to both the head and rocker cover degreased it will definitely seal well but won't come off in one piece next time .

**Q: How long does it take to dry**
A: Touch dry after about an hour, left it on for about 3 before I drove the car to be sure.

**Q: Can this be used on a car water pump upto 20psi? How long does it take to dry once metal surfaces are bolted together?**
A: i build jag engines up using this & no problems
best to leave for 24 hours if poss, 
have also fitted water pumps to later jags & used car straight away all ok GW

**Q: Is good to make a sump pan gasket, resistant to oil and high temperature?**
A: Would recommend it to anyone its is brilliant even put it on exhaust joint and it don't get any hotter than that!!!
