Expert Sealing Solutions

A blue polyurethane rod seal is a sealing element used in hydraulic systems to prevent fluid leakage between the rod and cylinder. Made from high-quality polyurethane, it offers excellent wear resistance, low friction, and strong protection against abrasion and extrusion. The blue color typically signifies a specific material type or enhances visual identification in various applications.
Also Diameter Available: 4-420mm

A red polyurethane hydraulic rod seal is a sealing component used in hydraulic systems to prevent leaks between the rod and cylinder. Made from durable polyurethane, it offers high wear resistance, excellent durability, and resistance to abrasion and extrusion, making it ideal for harsh operating conditions. The red color typically helps with identification or material specification.
Also Diameter Available: 0-500mm

Products Details:

• Rod and Wiper seals Rod and Wiper seals maintain sealing contact in sliding moon between the cylinder head and the piston rod. 
• Depending on the applicaon, a rod sealing system can consist of a rod seal and a Wiper seal or a rod seal only. 
• Rod sealing systems for heavy duty typically consist of a combinaon of both seal types, whereas the Wiper seal is arranged between the rod seal and the piston in the cylinder head. 
• Rod seals determine the tolerance for the rod diameter. 
• In addion to the sealing funcon, rod seals also provide a thin lubricaon film on the piston rod that lubricates themselves and the wiper seals. 
• The lubricant also inhibits corrosion of the piston rod surface.
• However, the lubricaon film must be thin enough so that it returns to the cylinder during the return stroke. 
• Selecng profiles and materials for a rod sealing system is a complex task, considering all possible cylinder designs and applicaon criteria. 
• We supplies rod and buffer seals in many different profiles and in a wide range of materials, series and sizes, which make them appropriate for a wide variety of operang condions and applicaons

Also Diameter Are Available: 5-400 mm

A white PTFE hydraulic rod seal is a sealing component made from polytetrafluoroethylene (PTFE), designed to prevent fluid leakage between the rod and cylinder in hydraulic systems. PTFE offers excellent chemical resistance, low friction, and high wear resistance, making it ideal for high-pressure and harsh environments. The white color often indicates the use of PTFE material for easy identification.
