CORTECO 19034038 FPM RHTC Rotary Shaft Oil Seal 42x55x6 mm

What is the CORTECO 19034038 Oil Seal?

The CORTECO 19034038 is a radial shaft oil seal (simmerring) manufactured from FPM (FKM fluoroelastomer) and designed in the RHTC sealing profile. With dimensions of 42x55x6 mm, it provides reliable sealing between rotating shafts and stationary housings in demanding automotive and industrial applications. FPM material offers excellent resistance to elevated temperatures, mineral and synthetic oils, fuels and many aggressive chemicals, making this seal suitable for long-term operation in harsh environments.

Construction and Operating Principle

The CORTECO 19034038 radial shaft seal is engineered to retain lubricant inside the assembly while preventing dirt, dust and moisture from entering the sealing system.

Its construction includes:

• FPM (FKM) fluoroelastomer sealing material
• RHTC seal profile
• Precision sealing lip
• Compact radial shaft seal design
• Right-hand hydrodynamic helix

The sealing lip maintains continuous contact with the shaft surface, helping to minimize lubricant leakage while protecting bearings and internal mechanical components against external contamination.
