To give a super-cozy finish, flannel is brushed on both sides, while brushed cotton is only brushed on the face side. For this reason, flannel is often fuzzier and warmer than brushed cotton.
'Cotton percale is great for sleepers who prefer a cooler and crisper feel. It is effortlessly smooth in both look and feel and is a great option for those with warmer body temperatures.

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.
Halogen lights are in fact the most commonly used headlights on most cars. Their invention dates back to the 1960s which was as a solution towards generating light with limited resources. Just like the incandescent lights, halogens use heated tungsten filament to produce light. The filament is however encased in a bubble of halogen gas unlike the incandescent, as a measure towards improving longevity and performance. These lights are easy to manufacture making the manufacturing process inexpensive. Moreover replacement costs are also very low. Halogen lights can fit most cars of different models as they come in different sizes and shapes. These lights however do not provide the best visibility as the white HID bulbs and LEDs. Quite a large amount of heat is lost while using these headlights and hence wasted energy. Moreover, they are very fragile requiring extra care unlike the LEDs and HID
For quality gaskets, Victor Reinz is the place to be. The German company invented the head gasket, but today it also specialises in other types of seals, including oil seals.
In the mechanical world, where machinery and equipment make the earth move and gears rotate, the oil seal is an important component. Oil seals, or shaft seals, are a crucial part of various industrial equipment and applications, ensuring that lubricants don’t escape and contaminants don’t enter. While they may seem simple, their construction, design, and application are anything but. This in-depth guide aims to help you understand the essential role of oil seals, their construction, the various designs available, and key factors to consider when selecting one for your application.
In conclusion, the ignition spark plug is a critical component of a vehicle's engine. It is responsible for igniting the air-fuel mixture and ensuring the engine runs smoothly. Regular maintenance and inspection of the spark plug are essential to ensure optimal engine performance. By understanding the importance of the ignition spark plug and taking proper care of it, you can help prolong the life of your vehicle and prevent potentially costly repairs.
custom molded gaskets. By eliminating the need for multiple gaskets to fit different parts of an application, manufacturers can reduce inventory costs and streamline their supply chain. They can also achieve better performance and longer life cycles by selecting the right material for the specific application.Leather
Recommended for abrasive applications
Good running properties, due to the impregnated seal lip
Can be used on shafts which have a surface roughness outside the range for rubber seals
Not suitable for water
The pulley is kept from turning on the crankshaft by a key fitting into grooves on the crankshaft and pulley.
