Engineered using high-grade German silicone polymers (Wacker Silicone) and precision-cast inside Italian master molds, KIEK Gaskets and O-Rings deliver leak-free fluid and gas sealing for modern automotive engines. Designed to resist chemical degradation from synthetic motor oils, high-pressure fuel sprays, and aggressive coolants, these gaskets maintain elastic memory and tensile strength over extended operating cycles without hardening or shrinking.

From specialized Viton (FKM) injector O-rings engineered for high-pressure fuel containment to PA6.6/ACM valve cover seals and composite multi-layer oil module kits, every component prevents fluid cross-contamination and pressure drops. Certified under the stringent quality supervision of DAkkS GERMANY, this seal range resists extreme thermal cycling, engine bay vibration, and fluid corrosion across major vehicle lines.

Main Functions of Engine Gaskets & O-Rings:

• Fluid Leakage Prevention: Creates positive mechanical barriers between mating engine flanges to contain engine oil, coolant, and fuel.
• Pressure Containment: Seals high-pressure air-fuel induction mixtures and exhaust combustion gas pathways from ambient leakage.
• Thermal Expansion Absorption: Compensates for thermal expansion differentials between dissimilar metal mating surfaces (e.g., aluminum cylinder heads and cast-iron/plastic intake manifolds).
• Vibration Dampening & Surface Imperfection Sealing: Fills micro-machining imperfections and dampens high-frequency valvetrain vibrations.

Supplementary Documentation: Guide & Maintenance

1. Installation Guidelines:

• Flange Surface Preparation: Thoroughly clean mating deck surfaces with an approved solvent to remove old gasket residue, oil film, and scale before installation. Never scratch aluminum faces with metal scrapers.
• Proper Alignment: Position gaskets strictly according to orientation markings (such as TOP or directional notches). Ensure O-rings seat flat in designated grooves without twisting or pinching.
• Torque Sequencing: Tighten flange bolts progressively in a criss-cross pattern using a calibrated torque wrench to prevent localized warping or gasket crushing.
• Avoid Unnecessary Sealants: Unless specified by factory manuals (e.g., applying sealant to cylinder block joints), install silicone and ACM gaskets dry to ensure unimpeded elastic expansion.

2. Failure Symptoms & Replacement Schedule:

• Symptoms of Blown or Degraded Seals: Visible oil/coolant drips under the vehicle, burning oil smell inside the cabin, loss of radiator coolant level without external leaks, rough engine idling due to vacuum leaks, or reduced fuel system rail pressure.
• Replacement Schedule: Gaskets and O-rings are single-use consumable components. Replace associated gaskets whenever disassembling engine manifolds, valve covers, oil pans, or cooling system housings.

3. Non-Repairability:

Gaskets and O-rings cannot be reconditioned, patched, or reused. Damaged, compressed, or heat-hardened seals must be replaced with new units during engine maintenance.
