In terms of maintenance, FRP chimneys require significantly less upkeep compared to conventional materials

Additionally, lubricants can be used on both sides of the oil seal to reduce friction and enhance sealing performance. The sealing process is crucial for preventing contaminants from entering machinery or equipment while keeping essential fluids contained within.
An oil seal type that is resistant to oils, fuels, and solvents, fluorosilicone also offers temperature stability. Primarily found in aerospace fuel applications and automotive fuel emission control, this o ring material is fast becoming popular in more and more oil-based applications across a wide spectrum of industries.

The black color of these spark plugs is a result of carbon buildup, which is a common issue that can occur over time due to normal engine wear and tear. This carbon buildup can negatively impact the performance of the spark plug, leading to misfires, rough idling, and poor fuel efficiency. It is important to regularly inspect and replace black spark plugs to ensure optimal engine performance.
Depending on the application, premium lip materials may need to be used, such as Ethylene-acrylic (Varmac®). This material features good abrasion and dry running capabilities, higher heat capabilities than nitrile and polyacrylate, and better low-temperature performance than polyacrylate.
