CORTECO 19036300 Valve Stem Seal 7x13/28x16 FPM VA09

Applications

The CORTECO 19036300 Valve Stem Seal (7x13/28x16 mm) is a high-precision rotary oil seal designed for industrial and automotive engines.
Manufactured from FPM (fluoro-rubber) in the VA09 variant, it ensures long-term resistance to oils, greases, fuels, and high temperatures.
This seal is directly compatible with DAF 1407706 and IVECO 2831287 part numbers, making it ideal for use in valve mechanisms, camshaft systems, turbochargers, and hydraulic or pneumatic drives.

Built to withstand continuous exposure to oil pressure, temperature variations, and vibration, it provides stable sealing performance and prevents both oil leakage and contamination ingress, even under demanding operating conditions.

Advantages

• FPM (Fluoro-rubber) construction - exceptional chemical and thermal resistance; operates reliably with engine oil, diesel, hydraulic fluids, and fuel vapors.

• Precision dimensions 7x13/28x16 mm - perfect fit for valve guides, maintaining optimal lubrication without oil loss.

• Designed for heavy-duty applications - recommended for service centers, OEM replacements, and maintenance departments requiring premium technical seals.

• High-durability rotary seal - minimizes downtime, supports continuous operation, and ensures long service intervals.

Technical Data

FAQ

Q1: What is the role of a valve stem seal in an engine?
A1: It prevents oil from entering the combustion chamber through the valve guides while allowing proper lubrication of the valve stem - essential for efficient combustion and reduced oil consumption.

Q2: Why choose an FPM seal instead of NBR?
A2: FPM (Viton®) offers superior heat and oil resistance, making it ideal for high-temperature environments and contact with aggressive lubricants or fuel residues.

Q3: Can this seal be used outside automotive applications?
A3: Yes, thanks to its material and dimensions, it is also suitable for industrial machinery, compressors, and pneumatic systems where precision sealing is required.

Q4: How do I select the correct valve stem seal size?
A4: Measure the valve stem diameter (7 mm), the guide bore (≈ 28 mm), and the seal height (16 mm). Always verify material compatibility with working fluids.
