Product Advantages
Superior Sealing Performance
The DAQ2 Hydraulic Seal from Forever Seals is engineered for bidirectional, leak-free operation. Its star-shaped elastomer design ensures a tight seal, even under high-pressure conditions of up to 40MPa. This eliminates media leakage, whether it's hydraulic oil, water, or gas, maintaining the integrity of your hydraulic system.
Exceptional Durability
With dual PTFE (Polytetrafluoroethylene) wear rings, the DAQ2 significantly reduces friction between moving parts. This not only ensures smooth operation but also minimizes wear and tear, extending the service life of both the seal and the associated hydraulic components. The anti-extrusion design further enhances durability by preventing the elastomer from being forced into gaps under high pressure.
Wide Temperature Adaptability
It can operate reliably in an extensive temperature range from -45℃ to +200℃. This makes it suitable for use in diverse industrial environments, from cold storage facilities to high-temperature manufacturing plants, without compromising on performance.
Low-Maintenance Design
Thanks to its durable construction and efficient sealing mechanism, the DAQ2 requires minimal maintenance. Fewer replacements mean reduced downtime for your equipment and lower overall operating costs.
Versatile Media Compatibility
Compatible with various media including hydraulic oil, water, and gas, the DAQ2 offers flexibility across different industrial applications, eliminating the need for multiple seal types.
Working Principle
The DAQ2 Hydraulic Seal consists of three key components: a star-shaped elastomer, dual PTFE wear rings, and an anti-extrusion structure.
When pressure is applied in the hydraulic system, the star-shaped elastomer deforms, creating a tight seal against the cylinder wall and piston. The PTFE wear rings act as a buffer, reducing friction as the piston moves back and forth. This low-friction movement not only ensures smooth operation but also helps to prevent damage to the seal and the cylinder.
The anti-extrusion rings come into play under high-pressure conditions. They prevent the elastomer from being extruded into the small gaps between the piston and cylinder, which could otherwise lead to seal failure. Together, these components work in harmony to provide reliable, long-lasting sealing for your hydraulic system.
Product Details
Material Composition
Star-shaped Elastomer: Made from high-quality nitrile rubber (NBR) or optional fluoroelastomer (FKM) for enhanced chemical resistance in aggressive media. NBR offers good elasticity and oil resistance, while FKM is ideal for harsh, corrosive environments.
PTFE Wear Rings: Crafted from premium PTFE, known for its low-friction properties, high temperature resistance, and chemical inertness, ensuring long-term smooth operation.
Anti-extrusion Rings: Constructed from durable materials to withstand high pressure, preventing elastomer extrusion and maintaining seal integrity.
Precision Engineering
Each component undergoes strict precision machining to ensure dimensional accuracy, allowing for a perfect fit within hydraulic systems. The surface finish of all parts is optimized to reduce friction and enhance sealing efficiency.
Structural Design
The star-shaped elastomer maximizes contact area with sealing surfaces, improving sealing effectiveness. The combination of wear rings and anti-extrusion rings creates a multi-layer protection system, ensuring the seal performs reliably under varying conditions.
Application Range
The DAQ2 Hydraulic Seal is widely applicable in:
Heavy machinery (construction, mining, agriculture)
Any hydraulic system requiring reliable sealing, high pressure resistance, and wide temperature adaptability.
