One of the key advantages of fiberglass trough covers is their durability and resilience. Made from a combination of fiberglass and resin, these covers are highly resistant to corrosion, rust, and weathering. This makes them ideal for use in outdoor environments where they may be exposed to harsh weather conditions. Additionally, fiberglass covers are lightweight and easy to install, making them a cost-effective solution for covering long spans of troughs and channels.

  • Oil leakage is one of the most common issues faced by vehicle owners, and a failing valve cover gasket is often the culprit. When this gasket wears out or deteriorates, it can lead to oil seeping into areas where it doesn't belong. Over time, this can affect the engine's lubrication, reducing its efficiency and potentially leading to more significant damage Over time, this can affect the engine's lubrication, reducing its efficiency and potentially leading to more significant damage Over time, this can affect the engine's lubrication, reducing its efficiency and potentially leading to more significant damage Over time, this can affect the engine's lubrication, reducing its efficiency and potentially leading to more significant damage4.0 valve cover gasket.

  • Oil seal with additional dust lip to prevent damage of sealing lip and to avoid the ingress of dust,dirt,water etc Into the system.

  • Seals, including oil seals, have undergone a great development in recent years and are totally unlike the original product. PTFE has taken over the oil seals market for modern engines mainly because traditional oil seals started causing more and more problems. Such as evaporation of chemical plasticisers from the elastomeric material, which eventually caused engine oil leakage. Now, the focus is more on durability and frequency of servicing.

  • Spark plugs are designed with a central electrode and a side electrode, separated by a tiny gap. When voltage from the ignition system jumps this gap, it creates a spark, which in turn ignites the compressed fuel and air inside the cylinder. This ignition triggers a controlled explosion, driving the piston down and ultimately turning the vehicle's wheels or performing whatever task the machine is designed for.
