SCR System Components: NOx, Urea Pump, Injector & Level Sensors

This page groups the four SCR component families in this catalogue: NOx sensors, urea pumps, urea injectors and urea level sensors. Together they account for 187 of the 422 catalogued entries — the single biggest system group in the range.

The pages below separate the four families so each can be specified by its own OE number: send the OE number of the component you are replacing, confirm its cross-reference against its own entry, and widen the order to neighbouring parts only where the same repair covers them as well.

Order by OE number, not by guesswork

An SCR repair can span several components on one truck: the NOx sensor, the pump module, the injector and the level sender can be quoted together. Send the OE numbers for whichever of them you are replacing — for the NOx sensor, numbers such as 5WK96612E; for the pump, 504381868; for the injector, 0444023019; for the sender, 1831371 — and each is matched to its own catalogue entry before a combined price comes back. Each component is confirmed against its own entry before the set is priced. Numbers not printed here are still checked against the full 422-entry catalogue on the application details you give.

Fitment confirmation checklist

Fitment is confirmed from the inquiry, so the inquiry has to carry the evidence: vehicle make and model, engine type, the OE number off the old part, and a note of any connector or mounting oddity. Engine detail carries particular weight for SCR system orders, since a single truck model can ship with different engines and different sensor specifications. The confirmation follows the applications listed on the catalogue entry itself, and where your model is not listed, that is stated plainly rather than glossed over. For a stock list, send the OE numbers in a spreadsheet for a line-by-line matched or not-matched reply.

Packaging, stock and dispatch

An SCR order can cover a set — sensor, pump, injector and sender for one truck — and one packaging choice can be applied across the whole consignment. The four options are the OEMEMBER branded box, the UAP branded box, and blue or white neutral boxes for distributors selling under their own label. Dispatch follows the catalogue's stated availability: more than 100 catalogued items can be dispatched within 3 days, and more than 2,700 within 15 days. Warranty terms for the order are confirmed in the quotation before payment. Product certificates are available upon request. Keep the confirmed numbers from a set order together in your records and quote them back on any repeat order.
