The manufacturing process of FRP rectangular tubes involves pultrusion, a technique that impregnates continuous glass fiber rovings with resin and then pulls them through a heated mold to form the desired shape
Moreover, the use of extension rods significantly enhances worker safety
Just like pressure. The temperature capability of the oil seal shouldn’t be lesser than the temperature of the application. This is because any significant increase or even decrease in the temperature will affect the functionality of the oil seal. PTFE seals have the highest temperature capability, making them useful for applications that demand harsh weather and elements.
• Total eccentricity, etc.
In conclusion, oil seals play a critical role in high-pressure systems by preventing leaks and maintaining the integrity of the machinery. With proper design, materials, and maintenance, high-pressure oil seals can withstand the extreme pressures and harsh conditions commonly found in industrial settings. By investing in quality seals and regular maintenance, operators can ensure the reliability and efficiency of their high-pressure systems for years to come.

Oil seals, also referred to as shaft seals, are widely used to prevent the leakage of medium (such as oils and grease) along a rotating shaft. This leak prevention is primarily achieved by the sealing element which can be made from a wide range of materials that are chosen according to each application. They are commonly used in gearboxes, hydraulic cylinders, and related components.
