HYDRAULIC GREASE FITTINGS
High-Performance Grease Fittings for Critical Applications
Our relationship with our supplier Kingfisher (Lubrication) Limited gives us access to their range of precise, durable, reliable, Aerospace Hydraulic Grease Fittings. Manufactured
in accordance with the SAE AS Series Standards and designed for extreme applications they afford leak-proof and
efficient performance for high-pressure lubrication systems ensuring smooth
operation in an environment where failure is not an option.
Why Kingfisher Aerospace Grease Fittings?
- Anti-Corrosion
Properties - Aerospace environments mean components are subjected to
hydraulic fluids, de-icing agents, and extreme temperatures. Our stainless
steel and Nickel Copper Alloy (Monel®) fittings provide superior
resistance to oxidation and chemical wear for long-term reliability.
- High
Temperature and Chemical Resistance-Durability - Monel® fittings are built
to withstand the influence of extreme heat and aggressive chemical
atmospheres, making them suitable for aerospace hydraulic systems that can
cause the degradation of standard materials over time.
- Precision
Engineered for Reliability - Accordingly, with strict adherence to SAE AS
standards, our grease fittings give a secure, leakage-free connection
preventing lubrication failure in mission-critical operations.
- Heavy-Duty
Performance - Made from steel, stainless steel, and Monel®, our fittings
can endure high pressures, heavy loads, and constant operational stress
whilst also minimising wear and failure.
- Low
Maintenance and Longevity - Built to last, our grease fittings
intermittently reduce the interval for replacement and maintenance,
keeping aircraft in operation longer while minimizing downtime.

Frequently Asked Questions
1. What are hydraulic grease fittings?
Hydraulic grease fittings (also known as grease nipples) are small mechanical components that allow grease to be injected into machinery under pressure. They provide a secure connection point for grease guns, ensuring efficient lubrication of moving parts in aerospace, defence, and industrial equipment.
2. What are grease fittings used for?
Grease fittings are used to deliver lubricant directly to components such as bearings, joints, and shafts without dismantling equipment. They are essential for maintaining smooth operation, reducing friction, and extending the lifespan of machinery in high-performance environments.
3. What types of hydraulic grease fittings are available?
Common types of hydraulic grease fittings in the UK include:
Straight grease nipples for easy access points
45° and 90° angled fittings for restricted spaces
Button head fittings for high-pressure, heavy-duty applications
Flush-type fittings for low-profile installations
Each type is designed to suit specific lubrication requirements and equipment layouts.
4. Are hydraulic grease fittings suitable for high-pressure applications?
Yes. High-pressure grease fittings are specifically designed to withstand demanding environments where lubricant must be delivered under significant pressure. Features such as ball check valves help prevent backflow and contamination, ensuring reliable performance.
5. What materials are grease fittings made from?
Hydraulic grease fittings are typically manufactured from durable materials such as:
Stainless steel for corrosion resistance
Zinc-plated steel for strength and durability
Brass for general-purpose applications
Material selection depends on the operating environment and application requirements.
6. Where are hydraulic grease fittings used?
Hydraulic grease fittings are widely used across:
Aerospace and defence systems
Industrial machinery and manufacturing equipment
Agricultural and construction machinery
Automotive and transport systems
They are essential in any application requiring regular lubrication and maintenance.
7. Can grease fittings be customised?
Yes. Custom grease fittings can be supplied in a range of sizes, thread types, angles, and materials to suit specific equipment and operational needs. This ensures optimal performance in specialist or high-spec applications.
8. Why are grease fittings important for maintenance?
Using hydraulic grease fittings allows for quick and effective lubrication, reducing downtime and preventing premature wear. Regular lubrication helps improve equipment reliability, efficiency, and safety, particularly in critical aerospace and industrial systems.
