CORTECO 49381571 FPM VA3 6-8 + VA3 6-112 Valve Stem Seal Set

Product Overview

CORTECO 49381571 is an FPM valve stem seal set comprising VA3 6-8 and VA3 6-112 seal versions for selected Mercedes-Benz applications. The seals control the amount of engine oil reaching the interface between the valve stem and valve guide during operation. Identification by CORTECO reference 49381571 and Mercedes-Benz OE numbers 0000530700 and A0000530700 supports accurate replacement selection.

Industrial Applications

CORTECO 49381571 is intended for engine cylinder head service, valve train repair and engine rebuilding in compatible Mercedes-Benz applications. Valve stem seals operate between the valve stem and guide, controlling oil flow into the valve area. The set is relevant for cylinder head rebuilding, valve replacement, engine overhaul, OEM replacement and professional powertrain maintenance.

Construction

The set uses CORTECO VA3 valve stem seal designs engineered for the reciprocating movement of engine valves. The sealing geometry maintains controlled contact with the valve stem while regulating lubricant transfer through the valve guide area. The set contains VA3 6-8 and VA3 6-112 versions, which must be installed in their specified positions according to the engine configuration.

Material

FPM fluoroelastomer provides high thermal resistance together with good resistance to engine oils and many automotive operating fluids. These properties make FPM suitable for valve stem sealing in the thermally demanding cylinder head environment. Actual service performance depends on temperature, lubricant compatibility, valve stem condition, guide clearance and correct installation.
