Fabric-rubber sealing ring type DT2

Fabric-rubber sealing ring type DT2

Technical specification: Fabric-rubber sealing ring type DT2

The DT2 sealing ring is a technically advanced fabric-rubber seal, designed for use in hydraulic systems, particularly for sealing pistons and plungers under high pressure conditions - up to 25 MPa. The product features high mechanical and chemical resistance, and its design ensures reliable operation even in challenging operating conditions.

Construction and material: The ring is made of technical cotton fabric, coated with nitrile rubber NBR. The elastomeric components have a hardness of 88° ShA (±5), providing the necessary elasticity and durability in prolonged contact with aggressive media.

Operating parameters:

• Operating pressure: up to 25 MPa

• Operating speed: up to 0.5 m/s

• Operating temperature range: from -30°C to +100°C

Chemical resistance: The DT2 ring exhibits very good resistance to:

• Mineral oils and greases

• Vegetable and animal origin oils

• Aliphatic hydrocarbons

• Non-flammable hydraulic fluids (HFA, HFB)

• Water (up to +60°C)

• Diluted acid and alkali solutions

Application: DT2 seals are used in hydraulic systems of industrial machines, presses, cylinders, and construction equipment, where high resistance to pressure and contact with various working media is required. Additionally, seals can be custom-made from materials tailored to specific working conditions not listed in the standard resistance table.

DT2 is a reliable choice for applications requiring solid and durable sealing under intense operating conditions.
