Automotive Spark Plug Boot Solutions

High-temperature resistance, Dielectric insulation, Manufacturing options, Consistent, high quality.

Fabricate spark plug boots with high-temperature resistance and consistent high quality. Provide dielectric insulation and gain manufacturing flexibility with Silastic silicone rubber for spark plug boots.

 

Meet market specifications for demanding spark plug boot applications

With proven XIAMETER® brand silicone high-consistency rubber (HCR) and liquid silicone rubber (LSR) elastomers, you can fabricate spark plug boots that:

  • Meet market demand for long-lasting, low-maintenance components
  • Provide critical dielectric (electrical insulating) protection required for automotive high-voltage cables, even in tight clearances against engine block
  • Maintain physical and dielectric properties over wide temperature ranges from -40 to 200ºC (-40 to 392ºF)
  • Provide long-term heat resistance
  • Withstand oil contact that would degrade organic materials

Gain manufacturing productivity

Learn from our fabrication experts how you can:  

  • Mold complex shapes to meet precise specifications and tolerances
  • Utilize LSRs for maximum process efficiency
  • Improve productivity with overmolding techniques
  • Achieve better-quality consistency

Create products that meet your customers' needs

 

Manufacture spark plug boots that:

  • Withstand high temperatures
  • Electrically insulate and protect
 


 

Manufacture spark plug boots that:

  • Maintain physical properties when exposed to continuous high temperatures 
  • Accommodate wide variations in temperature extremes
 

Specify the right elastomer


For engine ignition insulation and spark plug boots, we recommend a high consistency rubber (HCR) elastomer with a durometer between 40 and 70 Shore A, which can withstand temperatures as high as 316º C (600º F) and is able to be easily molded in compression, transfer, or injection molding machines.
