Nozzles and Valves
Nozzle and dosing valve inquiries linked to the injector category.
Aftertreatment Repair Parts
SCR support parts for distributors, repair shops, and fleet maintenance.
Solution support
This category is part of a complete SCR dosing sourcing solution.
Buyers often need more than a single replacement part. WEUP uses the product category as the starting point for OE matching, related-part planning, inspection workflow, and buyer-specific RFQ support.
OE Matching Solution
Turn OE/OEM numbers, sample photos, connector views, and vehicle data into a clearer sourcing direction.
Product Range Planning
Combine injectors, dosing modules, urea pumps, valves, nozzles, and SCR parts around buyer demand.
Quality & Packing Workflow
Support each quote with flow, spray, sealing, connector, traceability, export packing, and label checks.
Buyer-Specific RFQ Path
Separate distributor, repair network, fleet, and OEM / ODM needs so the quote asks the right questions.
By engine brand
Route brand searches into a safer matching workflow.
Engine brand pages help the buyer start the search, but the quote should still confirm OE number, sample photo, connector shape, application, and quantity.
