Typical Applications
Hylomar Gasket 3400 can be used as a gasketing compound between machined surfaces. It is ideal for sealing between mating faces on engines and transmission components where resistance to temperature and vibration are essential.
INSTRUCTIONS FOR USE
Hylomar Gasket 3400 should be applied to clean and dry surfaces, free of contamination such as oil or grease. The compound may be dispensed by hand from cartridge, concertina pack, or via a screen printing system. Once applied the joint should be assembled as soon as practical. Any excess compound can be easily wiped off external surfaces with a clean cloth soaked in Acetone or other suitable solvents.

Title: Upgrading Porsche Engine Gaskets: Benefits, Technical Specifications, and Considerations
Technical Specifications of Porsche Engine Gaskets:
High-quality material: Engine gaskets, whether original Porsche or aftermarket, are made from durable materials such as multi-layer steel (MLS) or high-grade rubber.
Perfect fit: These gaskets are designed specifically for Porsche engines, ensuring precise fitment and compatibility with the engine components.
Enhanced sealing: Engine gaskets provide an effective barrier against oil, coolant, and other fluids, preventing leaks and maintaining optimal engine performance.
Temperature resistance: Porsche engine gaskets are engineered to withstand high temperatures and maintain their sealing properties under extreme conditions.
Longevity: With their robust construction, engine gaskets offer long-lasting reliability and help extend the lifespan of your Porsche.
Benefits of Upgrading Porsche Engine Gaskets:
Improved performance: Upgrading to high-quality engine gaskets can enhance the sealing efficiency, leading to improved engine performance and power delivery.
Reduced risk of leaks: Upgraded gaskets minimize the chances of fluid leaks, preventing potential damage to engine components and reducing the risk of engine failure.
Enhanced durability: Engine gaskets made from premium materials offer superior resistance to wear and tear, ensuring longevity and minimizing the need for frequent replacements.
Compatibility assurance: OEM (original equipment manufacturer) or aftermarket engine gaskets designed for Porsche models guarantee compatibility, providing peace of mind during installation and usage.
Optimal sealing properties: High-quality gaskets help maintain proper compression ratios, prevent cross-contamination of fluids, and ensure efficient combustion, thereby maximizing engine efficiency.
When considering the purchase of original Porsche or aftermarket engine gaskets, there are several factors to keep in mind:
Compatibility: Ensure that the gaskets are specifically designed for your Porsche model and engine variant to ensure a proper fit and functionality.
Quality and reliability: Opt for gaskets made from reputable brands or original Porsche parts to ensure durability and reliable performance.
