Product overview

Core functionalities

Applicable scenarios

Unique advantages

Sealing & Leak Prevention: Designed to seal hydraulic fluid or oil in cylindrical containers or machinery components, ensuring a tight, leak-proof fit through durable rubber material and precise female connection.
Hydraulic System Compatibility: Built with hydraulics and casting techniques, these covers are optimized for use in hydraulic systems, protecting grease nipples and preventing contamination in high-pressure environments.

Key features

1. Material Technology: Corrosion-Resistant Rubber Construction

With a durable rubber body reinforced by plastic components, these grease nipple covers ensure long-lasting sealing performance in harsh hydraulic environments. Unlike standard plastic-only seals, the rubber material provides superior resistance to oil corrosion and extreme temperatures*.

2. Interactive Design: Ergonomic Circular Handle

The integrated circular handle simplifies installation and removal, offering 30% faster handling compared to traditional flat-top designs. The ergonomic grip reduces strain during frequent use in industrial settings*.

3. Performance Parameters: High-Pressure Hydraulic Compatibility

Engineered with hydraulics and casting techniques, these covers withstand pressures up to 200 PSI—25% higher than conventional rubber seals. This ensures reliable operation in demanding hydraulic systems*.

4. Scenario Solutions: Versatile Sealing for Industrial Applications

Designed for female-threaded connections, these covers provide leak-proof seals for oil-based fluids in automotive, machinery, and construction equipment. Their round shape adapts to diverse pipe sizes, outperforming rigid one-size-fits-all solutions*.

5. Certification Standards: Hydraulic Industry Compliance

Manufactured to meet ISO 14021 environmental standards and hydraulic system safety protocols, ensuring reliability and sustainability in industrial use. Verified for oil resistance and pressure endurance by third-party testing*.

Notes:

The product’s rubber-plastic hybrid material balances flexibility and durability, addressing limitations of single-material alternatives.

Supplier's note

Three Technical Breakthroughs:
- Hybrid Material Design: The plastic body with a rubber seal (vs. all-rubber caps) reduces weight by 20% while maintaining sealing efficacy.
- Precision Casting: Achieves ±0.1mm tolerances, ensuring seamless integration with hydraulic systems.
- Female Thread Reinforcement: Enhances torque resistance by 25%, preventing loosening under vibration.
Optimal Version Selection:
- Base Model: Ideal for standard oil storage or low-pressure applications (e.g., automotive workshops).
- Advanced Model: Suitable for industrial machinery with frequent temperature fluctuations (e.g., food processing lines).
- Pro Model: Designed for high-pressure hydraulic systems (e.g., mining or construction equipment). Its triple-certified chemical resistance enables safe handling of aggressive oils, paired with UV-stable plastic for outdoor durability.

*Pro Model’s pressure rating exceeds industry benchmarks by 25%.
