OE 0012301211 — Airmatic Compressor for Mercedes-Benz

Aftermarket airmatic compressor comes from tooling houses that hold the original drawings or licensed equivalents. KingMay sources from vetted factories and inspects each batch; the manufacturer name is available on request where your market requires origin documentation.

Build-year coverage is listed row by row in the Applications table above. Where several generations share one number, the newer rows usually carry a revised suffix — compare the last four characters before buying, since a suffix change often means a different connector or bracket.

Wholesale pricing for 0012301211 depends on order quantity, surface treatment and packing. Standard references are quoted ex-Guangzhou with tiered pricing from 10 pieces upward — send quantity and destination port and a quotation usually returns within one business day.

For a short distance at reduced load, usually yes — but the risk compounds. A degraded airmatic compressor transfers stress to neighbouring components, so a small repair can grow into a full cooling system rebuild. Book the replacement once the symptom is repeatable.

Three checks: the code printed on your old part must read 0012301211; the number must fall inside the build-year range in the Applications table; and the connector, thread or bolt pattern must match the reference photo. Codes cast into the housing are the most reliable source.

Yes, if the alternate shares the same engineering envelope. Shortlist candidates from the Related OE References table, then check bolt pattern, electrical pinout and material grade. A difference in any of those three means it is a different part, not a substitute.
