In the realm of industrial applications, selecting the appropriate O-ring material is crucial for ensuring the efficiency and longevity of machinery and systems. Two popular options are Viton and Teflon (PTFE) O-rings, each possessing unique characteristics suited to different environments and condi
How to Choose Correct Rubber Material?Application Requirements: Understand the specific requirements of your application, including the temperature range, pressure conditions, chemical exposure, and any other environmental factors that the rubber material will be exposed to. Different rubber materia
In high-pressure applications, achieving a reliable and leak-proof seal is critical. This is where EPDM bonded seals (also known as Dowty seals or gaskets) come into play. These specialized sealing devices combine the best properties of metal gaskets and rubber seals to provide an effective sealing
Valve stem seals are used in internal combustion engines to seal between the valve stem and the valve guide. They are typically located at the top of the valve stem, where the valve stem passes through the cylinder head.
The primary function of valve stem seals is to control the lubrication of the valve stem and prevent oil leakage into the combustion chamber. They play a vital role in maintaining proper engine performance, reducing oil consumption, and preventing issues such as oil burning, excessive oil consumption, and fouled spark plugs. Materials such as rubber, silicone, or other elastomers can withstand the high temperatures and pressures within the engine. They are designed to fit tightly around the valve stem and create a barrier preventing oil from entering the combustion chamber while allowing a thin oil film for lubrication.
