CORTECO 12018345 30x45x7 FPM Oil Seal B1BAVISLRDX7

Application - Shaft Seal for 1.9 JTD/CDTI Engines

The CORTECO 12018345 30x45x7 oil seal is a high-performance radial shaft seal (simmering) designed for demanding automotive and industrial applications. With dimensions 30x45x7 mm, it is commonly used as a camshaft seal in 1.9 JTD/CDTI engines and various vehicles from brands such as Alfa Romeo, Fiat, Opel, Saab, Nissan and others.

This rotary shaft seal is designed for right-hand rotation, ensuring optimal oil return and sealing performance when installed according to shaft direction. It functions as a reliable oil seal in engine assemblies and as a technical sealing solution in selected industrial machinery.

B1BASL Design - Durability and Sealing Efficiency

The construction type B1BAVISLRDX7 (B1BASL) features a primary sealing lip and an additional dust lip, classifying it as a double lip oil seal. This configuration protects against oil leakage while preventing dirt and contaminants from entering the system.

Manufactured from FPM (FKM) - Viton material, the seal offers excellent resistance to oils, greases, fuels and elevated temperatures. The metal-elastomer outer surface with ribbed design improves seating stability in the housing and reduces the risk of rotation within the bore.

As an original CORTECO product, this shaft seal ensures high durability, dimensional precision and long service life in high-speed and thermally demanding environments.

FAQ - Frequently Asked Questions

What is the difference between a single lip and double lip oil seal?
A double lip seal includes an additional dust lip that protects against contamination, while a single lip seal provides only primary oil sealing.

How do I select the correct shaft seal size?
The first dimension (30 mm) corresponds to the shaft diameter, the second (45 mm) to the housing bore, and the third (7 mm) to the width.

Why choose FPM FKM Viton instead of NBR?
FPM offers superior resistance to high temperatures, oils and aggressive chemicals, making it ideal for demanding engine and industrial applications.

Is this seal suitable for 1.9 JTD/CDTI engines?
Yes. CORTECO 12018345 is commonly used as a camshaft oil seal in these engine types.
