In addition to preventing leaks, oil seals also keep out dust, dirt, and other contaminants that could damage the components inside the equipment

20x35x7 oil seal. By sealing out these harmful particles, the oil seal helps to maintain the cleanliness and integrity of the mechanical system, prolonging its service life and reducing the need for costly repairs and replacements.

boom cylinder seal kit. Look for kits that are made from durable materials, such as nitrile or fluoroelastomer, and that are specifically designed for your application.


The reinforcement layer, usually accounting for 35% of the seal, is embedded within the rubber. This layer, often made of materials like fabric or steel, enhances the seal's strength and durability. It helps withstand high pressures and temperatures, preventing deformation or damage under extreme conditions. It also provides additional support to the rubber, maintaining its structural integrity over time It also provides additional support to the rubber, maintaining its structural integrity over time

For example, polyurethane is known for its excellent abrasion resistance and ability to maintain its seal under varying temperatures. Nitrile rubber, on the other hand, provides a good balance of chemical resistance and cost-effectiveness. Meanwhile, PTFE is often used in applications requiring very low friction and high chemical resistance Meanwhile, PTFE is often used in applications requiring very low friction and high chemical resistance

hydraulic seal kits.


The sealing lip is designed to conform to the shaft, creating a tight barrier that minimizes fluid escape
. Depending on the application, rotary shaft seals can be designed for various shaft diameters and operating conditions, including temperature extremes and high pressures.
