Coolant circuit seals

An OEM (Original Equipment Manufacturer) number is the reference code the vehicle manufacturer assigns to a part. An aftermarket part is produced by an independent manufacturer to match that reference. On PartsB2B every product lists its OEM cross-references, so you can confirm a supplier's part matches the number you are looking for.

Search by the OEM number printed on the original part, or browse this category and check the compatible vehicles listed on each product. Every product page shows the make, model, year range and engine variants the part fits.

Each product page lists the supplying company and its sales representatives. You can reach them directly by email or WhatsApp from the product or company page — PartsB2B does not sit between you and the supplier.
