Precision sealing
for Construction Vehicles
Construction Site Dust Finds Every Weak Point
Hydraulic systems and bearings operate continuously in environments filled with dust, dirt, and abrasive debris. Any loss of sealing integrity creates an entry point for contaminants, accelerating wear and reducing component life. Slow leaks often go unnoticed until hydraulic fluid levels drop below the level required for safe machine operation. On a jobsite where downtime directly impacts productivity and costs, an unexpected shutdown can be far more expensive than a preventive seal replacement.

Our Precision Sealing Solutions
O-Rings
O-rings are used throughout the fixed sealing interfaces of your equipment, from hydraulic system connections to gearbox housings. Their circular design minimizes installation errors, while the progressive deformation of the seal cross-section under compression creates an effective and reliable sealing barrier.
We offer a wide range of elastomer materials and hardness grades to match the compression loads and operating requirements of each application.
Rubber-to-Metal Bonded Seals
These seals address one of the most critical sealing challenges in highly loaded hydraulic systems: maintaining reliable sealing beneath bolt heads and threaded fittings.
Our design combines a rectangular-section metal washer with a bonded and vulcanized trapezoidal rubber sealing element. A thin positioning membrane ensures accurate centering during assembly.
This construction delivers excellent resistance to pressure and vibration, even under severe temperature conditions, making it particularly suited to demanding off-highway and construction equipment applications.
Surface Treatments
Even a perfectly engineered seal can underperform if its surface characteristics are not optimized for the application.
Our surface treatments are tailored to the intended operating conditions, whether the objective is to simplify installation, reduce friction during operation, or improve overall sealing performance. Each solution is custom-developed, tested, and validated according to your specifications, standards, and performance requirements.
