The FLEXI PRO Cylinder Head Gasket features a structure similar to the original gasket, enhanced with a copper fire ring, copper bridges, and a copper powder-infused silicone sealing strip using nanotechnology. This significantly increases thermal resistance, providing superior anti-burn performance and double the sealing integrity, especially in bi-fuel (CNG) engines. The FLEXI PRO gasket delivers better performance than the OEM gasket, particularly in engines with worn cylinder liner edges.
Main Functions of the FLEXI PRO Cylinder Head Gasket:
The primary role of any head gasket is to ensure a complete and reliable seal between the cylinder block and cylinder head, preventing fluid mixing and gas leaks. The FLEXI PRO gasket executes this with major enhancements:
- Complete Combustion Chamber Sealing:
- Equipped with a fireproof reinforced copper combustion ring and copper bridges, this gasket effectively seals high-pressure, high-temperature combustion gases.
- Heat resistance up to 400°C prevents gasket burn and maintains seal integrity under extreme operating conditions (such as bi-fuel engines).
- Oil and Coolant Passages Sealing:
- Utilizes copper powder-infused silicone sealing strips (via nanotechnology) alongside a full German WACKER silicone coating, guaranteeing a secure seal across oil and coolant routes.
- Prevents oil and coolant mixing in the radiator and offers exceptional resistance against oil, antifreeze, and radiator water.
- Heavy Operating Condition Resilience & Surface Flaw Compensation:
- Constructed with a hybrid structure of mineral fiber and German NBR latex, combined with an inner rust-proof galvanized layer, offering necessary flexibility and strength to withstand high pressure and engine vibrations.
- Outperforms OEM gaskets in engines with worn cylinder liner edges by effectively compensating for minor surface imperfections.
- Corrosion & Rust Resistance:
- Double-sided tin-plated rust-proof German galvanized inner layer enhances resistance against chemical corrosion caused by various engine fluids.
Installation Guide:
To ensure maximum efficiency and longevity of the FLEXI PRO cylinder head gasket, observe the following:
- Thorough Cleaning: Before installation, meticulously clean all contact surfaces on both the head and engine block from oil, water, carbon, or old gasket residue. Any tiny particles can cause leaks.
- Surface Inspection: Ensure both cylinder head and block mating surfaces are perfectly flat and free of warpage or deep scratches (skim/deck if necessary according to approved specs).
- Head Bolts: Using new, high-quality cylinder head bolts is recommended, as old bolts may have stretched and fail to apply proper torque.
- Sequence and Torque: Place the gasket in position and tighten the bolts strictly following the vehicle manufacturer’s recommended sequence and torque specifications. Incorrect torque or sequence can damage the gasket or cylinder head.
- No Adhesives or Sealants: Thanks to its full silicone coating and specialized sealing strips, the FLEXI PRO gasket requires NO additional glue, sealant, or gasket maker during installation. Dry installation is strongly recommended.
Maintenance & Periodic Inspection:
- Coolant Inspection: Regularly inspect coolant level, color, and quality. Bubbles in the radiator, coolant turning brown (indicating oil contamination), or unusual coolant drop may indicate gasket issues.
- Leak Inspection: Periodically check around the cylinder head-to-block seam for any oil or coolant leaks.
- Temperature Monitoring: Keep an eye on engine operating temperatures. Any abnormal temp spike can be an early signal of sealing issues.
Key Performance Advantages:
- Due to extreme heat resistance (up to 400°C), this gasket is an ideal, durable choice for bi-fuel (CNG) engines which run at higher combustion temperatures.
- Specially engineered design creates a reliable seal even in engines with slight wear on cylinder liner edges—a major advantage over standard OEM gaskets.
- Asbestos-free 3-layer standard structure guarantees high operational performance alongside environmental safety.
Technical Highlights:
- Nanotechnology integration in sealing strip manufacturing for enhanced precision.
- Infused with German WACKER copper powder within the silicone strip for higher heat tolerances.
- Full German WACKER silicone coating cured in 3 SYNCHRONIZED baking stages for superior durability and seal.
- European certifications under the authorization and supervision of DAkkS Germany, proving international quality compliance.
Storage:
- Keep the gasket in its original packaging in a dry, clean environment, away from direct sunlight.
- Strictly avoid bending, folding, or placing heavy objects on the gasket to prevent damaging its internal structure.
