Main Description

The CORTECO 12032076 FPM rotary shaft seal is a high-performance Simmerring® designed for professional use in industrial machinery, automotive powertrains and high-speed rotating equipment. Manufactured by Freudenberg, it offers precise and durable sealing of shafts exposed to oils, grease, fuel vapors and elevated operating temperatures. The premium FPM (Viton®) elastomer ensures exceptional chemical resistance, thermal stability and long service life, even in continuous-duty or high-load environments.

The BAUMSLX7 profile incorporates advanced lip geometry, supporting accurate alignment on the shaft and reducing friction while maintaining consistent sealing pressure. This makes the seal ideal for use in engines, pumps, compressors, hydraulic units, and transmission systems where long-term reliability is critical. As a rotary shaft seal and oil seal intended for professional B2B use, it delivers high durability, reduced wear, and strong resistance to deformation under dynamic loads.

Commonly used in both industrial and automotive sectors, the 35x62x7 FPM seal is selected for its stability under extreme temperature exposure, compatibility with synthetic and mineral oils, and outstanding resistance to aging. It is an excellent choice for applications requiring dependable rotary sealing, shaft sealing rings, and technical seals for heavy-duty environments.

FAQ

1. What is the difference between a single lip and a double lip oil seal?
A single lip (SC) seal provides primary sealing for oils and lubricants. A double lip (TC) design includes an additional dust lip for external contamination protection.

2. Is FPM suitable for high temperatures and aggressive oils?
Yes. FPM (Viton®) offers excellent thermal resistance and superior compatibility with oils, fuels and chemically active media.

3. How do I select the correct rotary shaft seal?
You must know the shaft diameter, housing bore, width, operating medium and expected temperature range.

4. Can this seal be used in automotive engines?
Yes. Its FPM construction and BAUMSLX7 profile make it suitable for engine, gearbox and hydraulic system sealing.

5. What are typical industrial applications for this seal?
Pumps, gearboxes, compressors, production machinery, hydraulic drives and general rotary equipment.
