Hydraulic NFPA Cylinders

Barrel: The barrel is usually high-strength steel to withstand internal pressure without distortion.

Cylinder Base: The cylinder base is strong and durable and is usually securely attached to the barrel by threads, welds, or tie rods.

Piston: Moves back and forth within the barrel under hydraulic pressure and may include wear bands to minimize metal-to-metal contact.

Piston Rod: The piston rod extends from the piston through the rod end of the cylinder and is usually chrome-plated to resist corrosion and minimize seal wear.

Piston Rod Connector: At the rod end of the cylinder, the gland contains dynamic and static seals to prevent leakage and wiper seals to remove contaminants.

Seals: High-pressure cylinders use seals that can withstand high pressures without extrusion or failure.

Ports: A high-pressure cylinder’s hydraulic fluid inlet and outlet ports are reinforced and designed to manage high-pressure flow without leakage.


For high-pressure applications, our HP Series high-pressure hydraulic NFPA cylinders stand out with their rugged design.


NFPA hydraulic cylinders are manufactured from high-strength metals to handle the rigors of high-pressure environments. This material not only provides the necessary strength, but also reduces wear and tear and the effects of external elements.The HP series cylinders are available in a wide range of working pressures to meet a variety of industrial needs.

Topa’s HP series cylinders are available in a variety of stroke lengths to meet the specific needs of each application. So our cylinders are capable of both short distance precision movement applications as well as wide reach tasks.


High-Pressure Operation: Engineered to work efficiently across a broad pressure range, suitable for rigorous industrial tasks.

Versatility: Available in multiple stroke lengths to accommodate diverse application needs.

Standardization: NFPA compliance ensures compatibility with a wide range of equipment and easy integration.

Customization: Offers options for different seals and mountings to meet unique operational requirements.


Manufacturing: Utilized in high-pressure pressing, clamping, and assembly operations.

Mining: Essential for drilling and excavation equipment that operates under high pressures.

Aerospace: Applied in testing and assembly rigs where precision under high pressure is critical.

Marine: Used in steering systems and lifting equipment on ships where robustness is required.

Agriculture: Employed in advanced tractors and harvesters for lifting and loading tasks.

High Pressure Hydraulic NFPA Cylinders (HP Series)

The production of the HP Series high pressure hydraulic NFPA cylinders is a rigorous process at Topa’s manufacturing facility. We select high-strength steel that can withstand high pressures to ensure the performance of each cylinder. During fabrication, we use state-of-the-art CNC machines to cut and shape the steel. Each component is designed to meet strict NFPA standards.

Next, technicians assemble each component to ensure a tight seal. Each cylinder is thoroughly pressure tested to ensure they can withstand high-pressure environments.
