hydraulic seals
Hydraulic seals are crucial in maintaining pressure and preventing fluid leakage within hydraulic systems—such as cylinders, pumps, and machinery operating under high loads. By ensuring a tight and reliable seal, they maximize efficiency, reduce downtime, and extend the service life of key components.
At Hengoseal.com, we offer a comprehensive lineup of hydraulic sealing solutions, each meticulously engineered to withstand demanding environments. Whether you require standard profiles or tailored configurations, our broad range of seals and materials can meet the specific challenges of your hydraulic applications.
Product details
- UN (TPU/FKM)
A versatile seal with excellent abrasion resistance (TPU) or high-temperature resilience (FKM). - IDU (TPU/NBR/FKM) & ODU (TPU/NBR/FKM)
Ideal for both rod and piston applications, these seals offer strong fluid compatibility and efficient sealing under pressure. - UHS/USH (TPU/NBR/FKM)
Designed for heavy-duty hydraulic cylinders, these seals effectively handle shocks and side loads. - DHS/LBH (TPU/NBR/FKM)
Provides reliable performance under varying temperature ranges, preventing leaks in tough environments. - J & OK (TPU/NBR/FKM)
Perfect for medium to high-pressure applications; robust design ensures consistent sealing over extended cycles. - FA (POM + NBR)
Combining a polymeric guide ring (POM) with NBR sealing lip, offering superior wear resistance. - UPH (TPU/NBR/FKM)
A highly resilient seal that accommodates minor misalignments while maintaining leak-tight performance. - KDAS (POM + TPU + NBR)
A multi-component design providing both sealing and guiding functions for complex cylinder arrangements. - V-Type Combination Seal (NBR + Fabric)
Reinforced with fabric for added strength and longevity in high-pressure, high-friction systems. - St-d Axle Use & St-d Hole Use (PTFE + BRONZE / NBR / FKM)
Precision seals for shaft or bore, using PTFE+Bronze for low friction and NBR/FKM for reliable fluid compatibility. - V-Ring (NBR)
A simple yet efficient design that protects against dirt, dust, and splash, commonly used as a secondary seal. - Guide Band (PTFE + BRONZE)
Helps maintain rod alignment, reducing metal-to-metal contact and prolonging seal life. - Quad-Ring Oil Seal (304ss + PTFE)
Incorporates stainless steel for rigidity and PTFE for a low-friction seal, ensuring longevity in harsh conditions. - YA (TPU)
Delivers flexible performance, particularly suitable for rapid reciprocating motions in hydraulic cylinders. - SPGW (3PTFE/BRONZE/NBR)
A robust, low-friction sealing solution often used in heavy machinery and high-load applications. - HBY (TPU + POM)
Combines the advantages of wear-resistant TPU with a rigid POM ring, offering both guidance and sealing.
Material & Construction
Our hydraulic seals integrate various materials:
- TPU (Thermoplastic Polyurethane): Excellent abrasion resistance for demanding uses.
- NBR (Buna-N): Good balance of oil resistance and affordability.
- FKM (Viton®): High heat and chemical resistance for extreme conditions.
- PTFE + Bronze: Low-friction composition that reduces wear and heat buildup.
- POM: A tough polymer providing enhanced support or guiding functions.
By selecting the right compound or combination, we ensure each seal performs reliably, even in high-pressure or high-temperature environments.
Why Hydraulic Seals Matter
Effective hydraulic sealing solutions:
- Prevent Fluid Loss: Maintain stable pressure for optimal system performance.
- Reduce Component Wear: Minimize friction and contamination, extending system life.
- Improve Efficiency: Enable smooth operation and reduce downtime in critical machinery.
- Enhance Safety: Control leaks and potential hazards in industrial settings.
