CORTECO 46083012 VMQ — rotary shaft oil seal 40x49.6x5.5

Applications

Designed for rotary shaft sealing in automotive drivelines and industrial gearboxes — commonly used as an output/shaft seal in Peugeot applications (OEM reference mapping available). Ideal for transmission, differential and auxiliary shafts operating under oil-lubricated conditions.

Advantages

• VMQ (silicone) elastomer: excellent resistance to temperature extremes, aging and a wide range of lubricants—beneficial where thermal stability and prolonged elasticity matter.

• Compact, low-profile design (5.5 mm height): fits tight housings while providing reliable static and dynamic sealing.

• Precision manufacturing: tight tolerances reduce leak paths and improve service life under rotary conditions.

Technical data

• Manufacturer / Code: CORTECO 46083012 (also offered as 46083012B).

• Inner diameter (d): 40.00 mm.

• Outer diameter (D): 49.60 mm.

• Width / height (W): 5.5 mm (low-section oil seal).

• Material: VMQ (silicone / MVQ) — high thermal stability and elastomeric resilience.

Main description

The CORTECO 46083012 VMQ rotary shaft seal is a purpose-built oil sealing ring for demanding automotive and industrial rotary applications. With an internal diameter of 40 mm, an outer diameter of 49.6 mm and a slim 5.5 mm cross-section, this VMQ (silicone) oil seal provides dependable rotary sealing in confined housings such as manual transmissions, differentials and gearbox shafts.

Manufactured to precise tolerances, the 46083012 seal features a resilient VMQ lip compound that combines excellent resistance to thermal ageing with compatibility with engine and gearbox oils, greases and common lubricants. The silicone-based elastomer maintains flexibility across a broad temperature range, reducing hardening and leak risk over long service intervals — a practical advantage for both passenger vehicle and industrial equipment service cycles.

This part is regularly cross-referenced to Peugeot driveline applications (OEM mapping includes vehicle references such as Peugeot item codes) and is supplied as an OE-grade aftermarket component by CORTECO. The compact profile makes it suitable for retrofits and replacements where space is limited, while the robust lip geometry ensures reliable dynamic sealing at typical shaft speeds and moderate shaft misalignment. For procurement teams and maintenance engineers, the 46083012 offers an optimal balance between installation convenience, material durability and cost efficiency.

FAQ

Q: What is VMQ and why choose it?
A: VMQ (silicone/MVQ) is a silicone elastomer with high temperature tolerance, excellent ageing resistance and good compatibility with many oils. It’s chosen where thermal stability and long-term elasticity are required. 

Q: Is this seal suitable for Peugeot transmissions?
A: Yes — CORTECO 46083012 is listed for Peugeot driveline applications and is supplied in automotive aftermarket channels for matching OEM reference numbers.

Q: How to confirm correct fit?
A: Verify inner/outer diameters (40x49.6 mm) and cross-section (5.5 mm). Cross-check OEM or housing drawing to confirm the low-profile design matches the seat depth. size.name

Q: What operating conditions suit this seal?
A: Best for oil-lubricated rotary shafts at standard automotive and industrial temperatures. VMQ handles a wide thermal window but verify chemical compatibility for specialty fluids
