At Pearson Hydraulics, we supply an extensive range of hydraulic seals and seal kits to keep your hydraulic systems operating efficiently and reliably. Whether you're repairing a leaking cylinder, overhauling a pump, or building a new system, our high-quality hydraulic seal kits provide the protection, performance, and peace of mind you need.

Hydraulic systems operate under extreme pressure, often up to hundreds of bar, making proper sealing critical to safe and effective performance. Our products are trusted across industries including agriculture, construction, manufacturing, marine, and industrial maintenance.

What Are Hydraulic Seals?

Hydraulic seals are specialised components designed to contain hydraulic fluid, prevent leakage, and maintain pressure within hydraulic cylinders, valves, and pumps. They separate the internal moving parts of hydraulic machinery and act as a barrier between different chambers, allowing the system to build and maintain pressure without fluid loss.

There are two main types of hydraulic seals:

• Bonded Seals
• Danfoss Seals

Both types are essential for system performance, ensuring fluid stays where it’s needed and preventing contamination from entering sensitive areas.

Our Hydraulic Seal Range

Pearson Hydraulics stocks a wide selection of individual hydraulic seals and complete seal kits, ready for fast dispatch across the UK. We only supply seals made from high-performance materials such as polyurethane (PU), nitrile rubber (NBR), Viton (FKM), PTFE, and other advanced elastomers – ensuring superior resistance to pressure, temperature, and wear.

Our collection includes:

• Rod Seals
  Installed on the rod side of a cylinder to prevent fluid from escaping as the rod extends and retracts. Our rod seals offer excellent wear resistance and sealing under varying loads and speeds.
• Piston Seals
  Designed to maintain pressure on the piston side of the cylinder, these seals prevent internal fluid transfer and maintain power in double-acting cylinders.
• Wiper Seals (Scrapers)
  Wiper seals keep contaminants like dirt, water, and debris from entering the hydraulic system as the rod moves in and out of the cylinder.
• Wear Rings
  Also known as guide rings, these components guide the piston and rod and prevent metal-to-metal contact inside the cylinder.
• O-Rings & Backup Rings
  O-rings are versatile and essential for static and dynamic sealing, while backup rings provide extra support for high-pressure applications.
• Complete Hydraulic Seal Kits
  To make maintenance easy and efficient, we also offer pre-packaged hydraulic seal kits tailored for specific cylinders, pumps, and machinery. These kits include all the necessary seals, wipers, and rings required for a complete rebuild or service — saving you time and hassle sourcing individual parts. 

Our seal kits are ideal for:

• Hydraulic cylinder repairs
• Agricultural and construction machinery maintenance
• Mobile plant servicing
• Industrial system overhauls
• OEM replacement and upgrades

If you can’t find the specific seal kit for your machine or application, just get in touch, we can help identify or source exactly what you need.

Benefits of Using Quality Hydraulic Seals
