Spark plug extensions, high tension leads, spark plug cables
Supported gas engine types:
The majority of spark plug extensions applied in the cable-program are made out of PTFE (polytetrafluoroethylene), a synthetic fluoropolymer of tetrafl uoroethylene which finds numerous applications. PTFE is most well known by the DuPont brand name Tefl on. PTFE is a fl uorocarbon solid, as it is a high molecular weight compound consisting wholly of carbon and fluorine. Neither water and water-containing substances nor oil and oil-containing substances are wet by PTFE , as fl uorocarbons demonstrate mitigated London dispersion forces due to the high electronegativity of fl uorine. It is very non-reactive, partly because of the strength of carbon–fl uorine bonds, and so it is often used in containers and pipe work for reactive and corrosive chemicals. Knowing this, it is obvious that this material is popular to be applied for spark plug cables. PTFE solid rod or tubing material can be easily machined, allowing for many shapes and sizes, required for a proper fit in the numerous different engines models that are running throughout the world. Hatraco is applying high grade PTFE, with respect to purity and electrical insulation.
Boots and connectors
A spark plug cable may appear to be a simple part. Functionality-wise it is - it only needs to ensure proper conductivity to allow the high tension pulse coming from the coil to go the spark plug, located somewhere remotely and deep in the cylinder head. Still, there is no world wide standard for spark plug cables and one needs to take in account that the product needs to fi t many different types of ignition coils and spark plugs.
There is no such thing as a standard connection and for that reason we offer our cables with many different connections. As the cable is sitting on top of the plug basically unsupported, many cables are furnished with some sort of cover boot or outer-o-ring to reduce vibration and/or prevent debris falling into the spark plug well. These boots are commonly made of EPDM or Silicone rubber. Both materials are high temperature resistant and offer excellent protection from oil and many other aggressive fluids. We also see many different types of connectors, commonly terminated with copper, brass or stainless steel contacts.
