Processing Info

Repair kits and spark plug seals are core sealing parts for engine maintenance, widely used in overhaul and servicing. Repair kits integrate various seals for one-step matching; spark plug seals prevent oil leakage into ignition system, ensuring stable engine operation.

Customization available by vehicle/engine model and working conditions via drawings, samples or parameters. One-stop supply of multiple seals lowers procurement cost with high matching efficiency.

Material Selection

NBR

HNBR

FKM

Silicone

NBR

NBR is widely used for engine seals, with good oil resistance and cost efficiency for general maintenance.

Ideal for oil sealing in repair kits and spark plug seals, a mainstream aftermarket option.

Features & Applications

• Good oil & fuel resistance

• Cost-effective for mass production

• For engine repair kits and basic spark plug seals

HNBR

HNBR offers better heat, aging and wear resistance for harsh engine conditions.

Used in high-end kits for high-temperature or long-life sealing parts.

Features & Applications

• Excellent heat & aging resistance

• Longer service life & higher stability

• For high-standard maintenance and matching parts

FKM

FKM features superior heat and chemical resistance for extreme working environments.

Applied in high-end models and high-temperature sealing parts.

Features & Applications

• Excellent heat, oil & chemical resistance

• For complex conditions and high-end uses

• For high-performance engine sealing

Silicone

Silicone has great temperature resistance and flexibility for special sealing.

Used for elastic parts in kits, not for main sealing in heavy oil conditions.

Features & Applications

• Wide temperature resistance range

• Good flexibility and easy installation

• For non-heavy oil or auxiliary sealing
