- a. Nitrile Rubber (NBR) – this is the most commonly used material. It has good heat resistance properties and has good resistance to salt solutions, oils, hydraulic oils, and gasoline. Operating temperatures are recommended from -40 to 248⁰ F (-40 to 120 deg.C). Nitrile also functions well in a dry environment, but only for intermittent periods. The disadvantage of this material is poor chemical resistance.
- Both the PTFE sealing lip and the shaft surface must be completely dry. Do not use grease or oil. If grease or oil is used, the retaining ring will fail after assembly.
Durability is another important factor to consider when choosing a spark plug, and the Spark Plug 794 00082 excels in this area as well. With its robust construction and high-quality materials, this spark plug is designed to withstand the rigors of daily driving and maintain its performance over the long term. This means that you can rely on this spark plug to provide consistent ignition performance, even in the most demanding driving conditions.
- In addition to their electrical properties, marine spark plug wires must also be flexible and durable enough to withstand the constant vibrations and movements experienced by boats
- Mechanical oil seals are essential components in machinery and equipment that require the containment of fluids such as oil and grease. These seals prevent leakage of these fluids and ensure that the equipment operates smoothly and efficiently.

Many seals come with a garter spring, found within the backside of the seal. It provides contracting pressure against the sealing surface. Making sure the spring seats correctly within the seal is an excellent first step.
