In textile manufacturing, sulphamic acid serves multiple purposes. It is involved in the dyeing process as a pH regulator, ensuring that colors adhere properly to fabrics. Moreover, it acts as a leveling agent, which helps to provide uniform dyeing results by preventing uneven uptake of dyes across different areas of the fabric. This characteristic is particularly important in the production of high-quality textile products, where color consistency is vital.

- The material composition of an oil seal is also essential. Typically, Oil Seal 20x35x7 is made from a combination of rubber (such as NBR, HNBR, or FKM) for flexibility and resilience, and a metal insert for strength and durability. The rubber compound allows the seal to adapt to different temperatures and chemical environments, while the metal reinforcement provides resistance against pressure and wear.

- Another important factor to consider when choosing a spark plug supplier is the quality of their products. High-quality spark plugs are essential for ensuring smooth engine operation and maximizing fuel efficiency. Look for suppliers who offer a range of spark plugs that are designed to meet the specific performance requirements of your engine.

An oil seal has two tasks: Keeping the lubricant in and keeping dirt and contaminants out of rotating components. This separation must be accomplished between surfaces in relative motion, usually a shaft or bearing inner ring and a housing. With correct installation, oil seals can also prevent seal leakage and maintain the lubricity of a bearing to ensure that the rotary shaft and its bearings remain fully functional.

First, an elastomer, most often nitrile, is vulcanised to a metal ring. This creates a stiffening effect that includes a specialised metal tension spring directly behind the sealing lip, keeping the oil seal firmly in place against the moving part.
Our suppliers try to provide the best quality oil seals and products are in some cases optimised to improve performance and fitment. Corteco is one of these brands, whose case studies we have listed for you.
Because of the higher temperature resistance of FKM, this material is also chosen for applications where higher speeds play a role, which raise the temperature at the sealing lip considerably. Usually, using FKM will result in a longer life than using NBR. This compensates the higher price of FKM compared to NBR, as an FKM does not have to be replaced as frequently. The low temperature resistance of standard FKM is limited to -15 ˚C.
Refit the distributor, ensuring that the rotor arm is exactly in line with the first mark. If not, withdraw the distributor and try again.
