Overview

Power generation equipment operates in harsh environments — extreme temperatures, ozone, UV radiation, and continuous vibration. Seals in gas turbines, wind turbine gearboxes, transformer bushings, solar inverters, and battery energy storage systems must provide decades of reliable service with minimal maintenance.

We supply EPDM for outdoor electrical enclosure and cooling water seals, FKM for high-temperature turbine and engine applications, and HNBR for transformer oil and lubricated gearbox seals. All materials are formulated for long-term aging resistance and validated for industrial power generation standards.

Frequently Asked Questions - Energy & Power

What O-ring material is best for outdoor solar inverters?

EPDM is the best choice for outdoor solar equipment due to its excellent ozone, UV and weathering resistance. It maintains sealing integrity for 20+ years in exposed conditions.

Can HNBR be used in transformer oil?

Yes. HNBR has excellent compatibility with mineral transformer oils and is commonly used in transformer bushings, tap changers and cooling system seals.

What seal material is used in gas turbines?

FKM is the standard material for gas turbine fuel and lubrication seals due to its high-temperature resistance up to +200°C. Special grades are available for aviation-derived industrial turbines.

Do wind turbine seals require special compounds?

Wind turbine gearbox seals often use HNBR for its oil resistance and mechanical strength. Nacelle enclosure seals use EPDM for weather and UV resistance.
