Wiper Seal

Product Details:

GPW Wiper Seals are a type of wiper seal used in hydraulic and pneumatic cylinders, specifically designed to remove dirt, debris, and contaminants from the rod as it moves in and out of the cylinder. These seals are crucial for protecting the internal sealing components, such as rod seals, from wear and damage caused by external contaminants.

DHS green wiper seals are widely available in numerous sizes, typically made from durable polyurethane (PU) material. The specific dimensions are identified by their inner diameter (ID), outer diameter (OD), and thickness/height. 

DHS wiper seals are primarily designed for industrial hydraulic systems to prevent contaminants like dust and moisture from entering the cylinder, a primary cause of seal and component failure. 

 

• Material: Most commonly made from Polyurethane (PU), which provides high abrasion resistance and durability.
• Color: The standard color for these PU seals is often green or blue.
• Hardness: They typically have a hardness rating of 90-93 Shore A, making them suitable for heavy-duty applications.
• Application: Used in hydraulic cylinders for industrial machinery.
• Design: The DHS profile is a double-lip wiper with a slightly rounded sealing edge to effectively scrape off dirt while leaving a residual oil film for lubrication.

A T06 PU wiper seal is a polyurethane (PU) hydraulic seal designed to prevent contaminants like dirt, dust, and moisture from entering a hydraulic cylinder system. The "T06" likely refers to a specific seal profile or design standard. Key Characteristics and FunctionWiper seals, also known as dust seals or scrapers, are crucial components in hydraulic systems, working in conjunction with other sealing elements to protect internal parts. 

• Contamination Elimination: The primary function is to scrape external contaminants from the reciprocating ram rod as it retracts into the cylinder, thus preventing damage to the rod, cylinder walls, and other seals.
• Material: The seal is made from polyurethane (PU), a durable polymer known for its high lubricity and resilience. This material contributes to low friction and a long operational life.
• Double-Edged (Optional): Some designs, often called "double-edged wipers", may feature a secondary lip to capture any small amount of oil that might have bypassed the main seal, while also removing bonded contaminants from the rod surface.
• Application: These seals are widely used in hydraulic machines for industrial use. 

Technical SpecificationsWhile specific dimensions vary by application, general performance parameters for PU wiper seals include: 

• Temperature Range: Typically suitable for temperatures ranging from approximately -40°C to +100°C (-40°F to +212°F).
• Maximum Pressure: Capable of handling pressures up to ≤40 MPA (megapascals).
• Maximum Speed: Designed to operate effectively at speeds of up to ≤0.5 m/s.
