NFPA Hydraulic Cylinder

Barrel: The barrel of the LH Series is constructed from high-strength steel, which ensures it can withstand high internal pressures.

Piston: The piston, central to the cylinder’s function, is precision-engineered to fit snugly within the barrel.

Piston Rod: It extends from the piston through the rod end of the cylinder to transmit the force generated by the hydraulic fluid to the machine.

End Caps: The end caps are securely attached to the barrel, typically through strong threading or bolts. They are designed to withstand the full force exerted by the pressurized fluid within the cylinder.

Seals and Bearings: The LH Series uses high-quality seals to prevent fluid leakage and minimize friction.

Ports: Hydraulic fluid enters and exits the cylinder through ports located on the cylinder barrel or end caps. These ports are designed to handle high-pressure fluid flow efficiently.


At Topa, our LH Series NFPA hydraulic cylinder has a modern, square appearance and rugged construction for working in demanding conditions.


In the manufacture of our high-pressure hydraulic NFPA cylinders (LH Series), we select high-grade steel for our hydraulic cylinders. Their strength and durability are guaranteed under high pressure conditions. These cylinders work through a hydraulic system that converts fluid pressure into mechanical force, providing smooth and efficient power transmission.

NFPA hydraulic cylinders are available in various sizes to accommodate different stroke lengths. Moreover, these cylinders are available in a wide range of pressures and can work efficiently in both low and high pressure environments.


Robust Material: The use of high-grade steel enhances the durability and resilience of the cylinders, making them suitable for rigorous use.

High-Pressure Capability: These cylinders are specifically designed to operate efficiently under high-pressure conditions, ensuring reliable performance in demanding environments.

Precision Engineering: The accurate design and construction result in consistent and efficient operation, critical for precision tasks.

Versatility in Stroke Lengths: With a variety of stroke lengths available, the LH Series can be adapted to suit a wide range of applications and requirements.


Manufacturing: Used in machinery requiring precise and powerful movement, such as in pressing and assembly lines.

Construction Equipment: Essential in heavy machinery like cranes, excavators, and bulldozers where high pressure and reliability are crucial.

Mining Operations: Ideal for drilling and earth-moving equipment, capable of withstanding harsh working conditions.

Agricultural Machinery: Used in high-performance agricultural equipment for tasks such as plowing and harvesting.

Material Handling: Applied in forklifts, loaders, and other material handling equipment where precision and strength are needed.

Pressure Rated NFPA Hydraulic Cylinder (LH Series)

The manufacturing process for our high-pressure hydraulic NFPA cylinders involves a series of precision steps to ensure the highest quality and performance. First, we select top-quality materials. Then, we use CNC machine tools to grind and manufacture each component to ensure they are dimensionally accurate.

After machining, our technicians rigorously assemble each part to ensure a perfect fit and airtight seal. We then subject the cylinders to a series of rigorous tests, including pressure and leakage tests, to ensure optimal performance under high-pressure conditions.

When you need a reliable and efficient high-pressure hydraulic solution, consider the LH Series in our NFPA cylinder lineup. Contact us and let us manufacture a specialized cylinder for you.
