Product Information
Product Information
Hylomar Gasket 3400 is a modified anaerobic curing, flexible sealant designed to become a Formed in Place (FIP) Gasket when cured. The cured compound has good temperature resistance and high resistance to fretting. The cure is initiated when the compound is in contact with metal ions and in anaerobic conditions. The cure rate and final strength is dependent on the metals being joined and the temperature at which the component is used. The heat generated by a running engine will accelerate the cure.

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.

About Gaskets & Sets

Engine Gaskets & Gasket Sets – Precision Sealing for Porsche Engines

Engine gaskets are vital components that ensure your Porsche’s engine operates efficiently and leak-free. Positioned between key engine surfaces such as the cylinder head, intake manifold, and oil pan, gaskets maintain a perfect seal against high temperatures, pressures, and fluids.

At Design911, we offer a comprehensive range of engine gaskets, seals, and complete gasket kits for Porsche models of every generation. Each gasket is crafted from high-quality composite, metal, or elastomer materials to withstand the extreme conditions of high-performance engines — ensuring optimal sealing, reduced oil and coolant leaks, and consistent compression.

Whether you’re rebuilding a classic 911 flat-six or servicing a modern turbocharged Porsche engine, our manufacturer-quality gaskets and complete kits guarantee reliability, performance, and peace of mind.

What Do Engine Gaskets and Gasket Sets Do?

Gaskets play a critical role in ensuring that various engine systems — combustion, lubrication, and cooling — remain properly sealed.

Core Functions:

  • Prevent leaks of oil, coolant, air, and combustion gases.
  • Maintain compression between the engine block and cylinder head.
  • Ensure efficient combustion and proper engine pressure balance.
  • Protect internal components from cross-contamination of fluids.

A properly sealed engine not only improves performance and efficiency but also prevents costly long-term damage.

Why Do Gaskets Fail?

Despite their durability, gaskets naturally degrade over time due to extreme heat cycles, pressure variations, and material fatigue.

Common Causes of Gasket Failure Include:

  • Overheating, causing warping or breakdown of the gasket material.
  • Improper installation or torqueing during assembly.
  • Aging materials that harden or crack with use.
  • Chemical degradation from oil or coolant exposure.
  • Uneven pressure or engine vibration, leading to micro-leaks.

Typical symptoms of gasket failure include oil or coolant leaks, reduced compression, overheating, or visible residue at gasket joints.

Why Replace with Precision-Engineered Gaskets and Kits?

Replacing worn or leaking gaskets is essential to maintain proper engine compression, prevent contamination, and restore overall reliability. Our direct-fit gasket sets and kits are designed to meet or exceed Porsche engineering standards, providing complete sealing solutions for rebuilds and maintenance.
