To act as a physical barrier retaining the lubricating oil where it is bound to be.
- In addition, the A5RTC spark plug is easy to install and replace, making it a convenient option for both professional mechanics and DIY enthusiasts. Its compatibility with a wide range of engines also makes it a versatile choice for various applications.
- The rubber component, typically made from high-quality elastomers, provides the seal with the necessary elasticity to adapt to different temperatures and maintain a tight fit within the mechanical assembly. It ensures a reliable barrier against oil leakage, preventing contamination and maintaining the integrity of the lubrication system.
- If you find that any of your spark plug wires are worn or damaged, it is important to replace them as soon as possible. Replacing worn or damaged spark plug wires can improve engine performance, reduce fuel consumption, and prevent potential engine damage. It is recommended to replace all spark plug wires at the same time to ensure that they are all in sync and functioning properly.
Generally, oil seals vary in materials and types based on the corresponding application. Common materials include:
- Regular maintenance and inspection of oil seals are crucial. During routine services, mechanics check for signs of leaks, discoloration, or hardening, which might indicate a seal needing replacement During routine services, mechanics check for signs of leaks, discoloration, or hardening, which might indicate a seal needing replacement

Choosing Quality Oil Seals for Wheel Hubs and Steering Mechanisms
The main causes of external lubricant leakage from pumping systems, hydraulic machines, gearcases and sumps are the wrong selection, improper application, poor installation and inadequate maintenance practices that are applied to sealing systems.
ERIKS type R (type A according to the DIN standard) is identical in shape to type M, but has a rubber outer case with metal reinforcement on the inside. The rubber creates a good seal in the housing, even if the housing has suffered minor damage or is not in its best condition for other reasons. The RST version has a dust lip. These types are often chosen to replace a type with a metal outer case because they are easier to install and can cope with minor damage to the groove, such as scratches.
Another factor that can affect the cost of new spark plugs is the brand. Some well-known brands in the automotive industry may charge a premium for their spark plugs due to their reputation for quality and reliability. However, there are also more affordable brands that offer reliable performance at a lower cost.

Oil seals require sufficient time to solidify and cure. Premature use of equipment with newly installed oil seals can compromise the integrity of the oil seal and may damage your machine. Refer to the supplied instructions for the time frame allocated for the seal to cure.
Begin with a thorough inspection of all involved surfaces:shaft sealing surface and housing bore, seal lip(s), and outside diameter. Maintaining the integrity of the sealing lips is “Priority 1″. The slightest tear or nick can develop into a more significant issue during operation.
Metal inserts must be carefully prepared in operations involving cleaning and roughening surfaces (grit-blasting or phosphatizing), stamping out parts, application of primer (usually by dipping), and curing of the primer (often by baking for a short time at moderate temperature).3 Primer curing minimizes the possibility of wiping primer off portions of the insert by stock flow during molding. The treated metal inserts must be used within a relatively short time (usually a day or less), so that functionality necessary for bonding is not lost by reaction with moisture in the air. Freshness of the primer surface is particularly important for peroxide-cured and base-resistant fluoroelastomer compounds. Compound formulation should be adjusted to attain good adhesion.

The best seal performance is achieved when close shaft and bore tolerances are present. Other factors include shaft eccentricity, end play and vibration.

Leather Oil Seals - Leather Seals, also known as Type L Oil Seals, are most common in components that are subject to dirt and poor lubrication. Since they come pre-lubricated and are able to absorb fluids, leather oil seals are able to provide sealing properties in conditions that synthetic rubber is unable to.
Operating conditions such as the engine’s temperature, position, size, pressure and shaft speed largely determine which individual oil seal composition is most suitable for every individual application.
