CORTECO 12015425 FPM 25x42x7 - rotary shaft seal

Engine oil seal for camshaft and rotating shafts

High durability and resistance to oils and temperature

Main description

The CORTECO 12015425 FPM 25x42x7 is a high-performance rotary shaft seal, designed for reliable sealing of rotating shafts in internal combustion engines and demanding industrial applications. This precision oil seal effectively prevents oil leakage while protecting the system against external contaminants such as dust, moisture and particles.

Manufactured from FPM (FKM) elastomer, the seal offers excellent resistance to oils and grease, high operating temperatures and chemical exposure. This makes it suitable for long-term operation in engines and machinery subjected to continuous load, elevated temperatures and dynamic shaft movement. As a professional technical seal, it maintains stable sealing performance even under intensive operating conditions.

The BASLRDX7 design ensures consistent rotary sealing and controlled contact pressure between the sealing lip and the shaft surface. This construction supports reliable lubrication retention, reduced wear and extended service life of both the seal and the shaft. Depending on the application, the seal can function as a single lip oil seal or as part of a more complex sealing system in automotive and industrial assemblies.

With standardized dimensions of 25x42x7 mm, this shaft sealing ring is widely used as an engine seal, including camshaft sealing applications, as well as in gear drives and auxiliary rotating components. Compatibility with multiple OEM references allows easy replacement during maintenance, overhaul and professional service operations.

The manufacturing quality associated with CORTECO guarantees high durability, dimensional accuracy and stable performance over extended operating cycles. This rotary oil seal is well suited for hydraulic and automotive seals applications where reliability and material resistance are critical.
