Oil Seal referred to as a shaft seal or rotary shaft seal, is a specialized type of rubber seal used to prevent the leakage of lubricants, oils, or other fluids in rotating or reciprocating machinery. It is specifically designed to seal the gap between a rotating or moving shaft and the housing or component it passes through. 

A rubber O-ring, also known as a rubber seal ring or toroidal seal, is a circular-shaped mechanical gasket made from elastomeric materials. It is one of the most commonly used types of seals due to its simple design and effectiveness in creating a reliable, leak-proof seal.
Rubber O-rings are typically made from materials like natural rubber or synthetic compounds such as nitrile rubber (NBR), silicone rubber (VMQ), fluorocarbon rubber (FKM), or EPDM (ethylene propylene diene monomer). These materials offer excellent sealing properties, including flexibility, resilience, chemical resistance, and temperature resistance.

Bonded seal called Dowty seal or a sealing washer, is a specialized type of sealing device used to create a reliable and leak-proof seal in high-pressure applications. It combines the properties of a metal washer and a rubber seal, providing an effective sealing solution for threaded connections.
They consists of a metal washer with a rubber sealing ring bonded to its inner diameter. 

Rubber parts refer to various components made from rubber materials that are used in a wide range of industries and applications. It was find applications across numerous industries due to their versatility and ability to provide sealing, vibration isolation, cushioning, insulation, and other functional properties.

Rubber gasket is a mechanical seal made from rubber or elastomeric materials. It is used to create a tight and reliable seal between two or more mating surfaces. Rubber gaskets are designed to prevent the leakage of fluids, gases, or contaminants, and to provide cushioning, vibration isolation, and resistance to environmental factors. It was come in various shapes, sizes, and thicknesses to suit different applications. 

Rubber ball is a spherical object made primarily from rubber or elastomeric materials. It is commonly used in various applications, ranging from sports and recreational activities to industrial uses. Rubber balls are known for their resilience, bounce, and versatility. It was come in different sizes, densities, and compositions to suit specific purposes. They can be solid or hollow, and their surface may be smooth or textured, depending on the intended use. The manufacturing process involves molding or shaping the rubber material into a spherical form and curing it to achieve the desired properties.

Hydraulic and pneumatic seals are essential components used in systems that rely on fluid or gas power transmission. These seals provide crucial sealing functions, preventing leakage and maintaining the integrity of hydraulic and pneumatic systems. They are designed to withstand high pressures, temperature variations, and the rigors of demanding industrial applications. It was ensure that hydraulic cylinders, pumps, valves, and other components remain sealed, allowing for efficient power transmission and controlled movement. They are typically made of elastomeric materials such as rubber or polyurethane. These materials are chosen for their resilience, flexibility, and resistance to wear, friction, and various operating conditions. The seals are designed in various shapes and configurations, including O-rings, lip seals, rod seals, piston seals, and wipers, to suit specific sealing requirements.

Silicone products are items made from silicone, a synthetic polymer composed of silicon, oxygen, carbon, and hydrogen. Silicone exhibits a range of unique properties that make it suitable for a wide array of applications. It is known for its excellent temperature resistance, flexibility, low toxicity, and durability, it was usually have: Silicone Sealants, Silicone Gaskets and O-rings,Silicone Adhesives,Silicone Tubing and Hoses,Silicone Bakeware and Kitchenware,Silicone Medical Devices,Silicone Personal Care Products,Silicone Automotive Components.

Plastic products offer numerous advantages, including versatility, durability, lightweight nature, cost-effectiveness, design flexibility, and resistance to corrosion, moisture, and chemicals. It was can be categorized into different types based on their composition and properties, usually have: Packaging Materials, Household and Consumer Goods, Building and Construction Materials, Automotive Components, Electronics and Electrical Products,Medical Devices and Equipment,Agricultural and Horticultural Applications,Sports and Leisure Products...
