Cover Plates

Cover plates are flat, machined components designed to bolt onto a hydraulic manifold or valve interface. Their primary function is to:

• Seal unused connection faces – preventing fluid leakage and contamination

• Enable modular system design – allowing future expansion or reconfiguration

• Maintain pressure integrity – ensuring safe and reliable operation

They are available in multiple sizes and standards to match the dimensions of hydraulic valves and manifolds.

• Leak prevention – ensures unused ports remain securely sealed

• System flexibility – supports modular hydraulic designs and easy upgrades

• Durable construction – built to withstand high pressures and harsh environments

• Easy installation – simple bolted design for quick fitting and removal

• Cost-effective solution – protects system integrity without complex components

Cover plates are widely used in:

• Industrial hydraulic manifolds

• Mobile machinery hydraulic blocks

• Marine and offshore hydraulic systems

• Energy and utility installations

• Custom hydraulic power units

They are particularly valuable in systems where modularity and adaptability are required.

 We source hydraulic cover plates from a wide network of manufacturers, including:

Bosch Rexroth … and many more

As an independent supplier, we provide unbiased recommendations based on your system’s needs – not a manufacturer’s catalogue.

Do cover plates affect system performance? No – they simply close unused ports and maintain system integrity without altering hydraulic function.

Can cover plates be reused? Yes – provided they remain undamaged and the sealing surfaces are intact.

Are cover plates available in different sizes? Absolutely. We supply cover plates to match a wide range of valve and manifold standards.
