High-Pressure Intensifier

We were approached to support an urgent high profile MRO application requirement. The remit was to both reverse engineer and modify a Spring-Force Gland/Packing assembly.

The brief was to provide replacement seals for a high-pressure system, rated up to 100,000 psi. Working with a media of 95/5 water-based fluid and ambient temperatures, the challenge was to provide a solution as quickly as possible to minimise downtime.

Reduce Maintenance Costs and Downtime

In sectors like agriculture and heavy industry, where machinery operates in harsh, high-demand environments, the risk of failure due to poor sealing can lead to costly repairs and production delays. Our seals and gaskets are engineered to prevent contaminants, leaks, and wear, which helps reduce maintenance costs and downtime - ultimately improving the efficiency and profitability of your operation.

Heavy Industry and Agriculture Sealing Products

Whether you're in construction, mining, farming, or industrial machinery manufacturing, we offer a range of sealing products tailored to your specific needs. Our solutions are designed to withstand extreme temperatures, pressures, and environmental conditions, helping you maximise uptime and optimise the lifespan of your equipment.

O-Rings	Reliable, cost-effective, and versatile, our O-rings are designed for static and dynamic sealing applications. Available in a variety of elastomers, they provide long-lasting performance against oils, fuels, and environmental factors.
Gaskets	Our high-quality gaskets ensure a secure, leak-proof seal for heavy industrial and agricultural machinery, even in tough, high-pressure environments. Designed for critical applications such as engines, pumps, and hydraulic systems.
Rotary Seals	Our rotary seals protect rotating shafts from contaminants and fluid leakage. Whether used in gearboxes, pumps, or hydraulic motors, these seals provide exceptional sealing capabilities in both high-speed and high-pressure applications.
Hydraulic Seals	Designed for high-pressure systems, typically used in agricultural and heavy industrial machinery. With precision and durability, these seals ensure smooth operation and minimise the risk of leaks and failures in hydraulic applications.
Rod Seals	Rod seals keep high-pressure fluid inside the cylinder while allowing the rod to move and prevent fluid leakage along the rod shaft. Commonly used in hydraulic cylinders in excavators, loaders, tractors and in agricultural sprayers, balers, and construction equipment.
Wiper Seals	Our wiper seals are used in conjunction with rod seals, to protect them from contamination (dirt, dust, moisture), to increase the lifespan of hydraulic cylinders. Essential in outdoor or dirty environments.
Piston Seals	Critical for the function of double-acting cylinders, our piston seals provide controlled movement in hydraulic presses, backhoes, and sprayers to ensure efficiency and control in heavy lifting and soil preparation equipment.
V-Rings	V-rings provide extra protection in harsh field conditions, protecting against dirt, dust, and liquid ingress. Used on rotating shafts in pumps, gearboxes, and motors and common in tractors and combine harvesters where shaft sealing is needed in dusty or wet environments.
Back-up Rings	Provides additional support to the primary seal, to significantly extend the life of the seal and prevent extrusion, which can cause leaks and system failures in extreme pressure or temperature scenarios. Ideal for hydraulic valves and pumps in industrial presses or tractors and improves reliability in deep tillage or drilling machinery.
X-Rings / Quad Rings	Quad rings reduce wear and extend service intervals in hydraulic and pneumatic cylinders, and they offer better seal stability in agricultural implement linkages and mobile hydraulic units. The preferred choice in vibrating or pulsating equipment due to superior performance.
Custom Sealing Solutions	Tailored sealing solutions that meet unique operational challenges. From farming equipment to mining machinery, we create seals that ensure your equipment operates at peak efficiency, reducing downtime and maintenance costs.
