In piping systems, square rubber gaskets are used to seal joints and connections, preventing leaks and ensuring the integrity of the system
. These gaskets are available in different thicknesses and sizes to accommodate various pipe diameters and pressure ratings.- In conclusion, petrol engine spark plugs are indispensable components of the ignition system, responsible for igniting the air-fuel mixture and powering your vehicle. With the right design, materials, and maintenance, these tiny devices can provide reliable and efficient performance for thousands of miles to come.
- The elasticity and flexibility of silicone gaskets enable them to conform to irregular surfaces, creating a tight seal that prevents leaks and protects sensitive components

When selecting oil seals for wheel hubs and steering mechanisms, it is essential to prioritize quality, durability, and compatibility with specific vehicle models. High-quality oil seals are designed to withstand the demanding conditions of automotive operation, providing reliable sealing solutions that contribute to the overall performance and safety of the vehicle. Choosing reputable suppliers and manufacturers known for producing high-quality oil seals is crucial to ensure the reliability and longevity of these critical components.
Oil seals are typically classified based on their sealing capabilities, with common types including lip seals, mechanical seals, and hydraulic seals. Lip seals are the most basic type, consisting of a flexible lip that seals against the shaft. Mechanical seals use sliding or rotating components to create a seal, while hydraulic seals are designed for high-pressure applications.
As can be seen from the seal cross-section shown in Fig. 14.2, shaft seals are complex shapes that require advanced mold design and molding techniques (see Section 7.3 for discussion of fluoroelastomer molding). For some time, most shaft seals were made in the United States by compression molding. Injection molding of shaft seals is prevalent in Europe, and is being used increasingly in the United States. An advantage of compression molding is that preforms (usually rings cut from extruded tubing) are used that closely approximate the amount of stock required for the final parts, so compound waste is minimized. For injection molding, the amount of cured stock in the central sprue and runner (actually a thin sheet leading to the seal lip) is often large compared to the stock required for the final part, so the waste of high-cost fluoroelastomer may be high. Such waste is reduced in modern injection molding designs.

Oil seal specifications
Operating temperatures for engine oil seals (see Fig. 14.11 and cross-section of lip seal with garter spring in Fig. 14.22) vary widely, depending on engine design and location within the engine. Typically, the rear crankshaft seal is subjected to much higher temperatures than the front seal. Oil sump temperatures vary considerably, depending on provisions for oil cooling. This allows use of hydrogenated nitrile (HNBR), silicone, or acrylic elastomers for some seals in relatively low-temperature environments (120–140°C or 250–284°F). Standard fluoroelastomers (FKM), bisphenol-cured VDF/HFP/TFE terpolymers with 68–69% fluorine content, perform well in oil service up to about 160°C (320°F). More resistant fluoroelastomers are necessary for reliable long-term performance in more severe environments.
Another factor you need to consider is the type of lubricants that are more suitable for the seals. Check for the appropriate viscosity of the lubricant that’s compatible with the seal material.
Leather is probably the oldest of the lip materials still in common use, but the move towards mass production methods has seen a massive increase in the development of synthetic rubbers which lend themselves to accurate and repeatable injection and compression moulding. Nitrile (NBR) is still by far the most common elastomer for “normal” use, whilst Viton® (FKM/FPM) is rapidly replacing Polyacrylate (ACM) and Silicone (VMQ) for high-temperature applications. Viton® also has high resistance to abrasion and chemical attack making it a preferred elastomer. Recent developments in the use of PTFE for Rotary shaft seals has caused widespread interest particularly for high-speed shaft rotation or poor lubrication applications.
