Technical Specifications & Cross Reference

Cross reference: Donaldson P550086 and other numbers with the same thread, gasket diameter and height are interchangeable. Send your engine model, VIN or the number printed on the old filter and we confirm the exact match before shipping.

Manufacturing Quality

Manufactured in an ISO 9001 certified plant: galvanised steel shell, rolled seam for burst resistance, anti-drain back valve and bypass valve tested on every batch, plus a high efficiency pleated element that keeps pressure drop low while holding more contaminant. Each unit is leak tested and packed in an individual box to survive sea freight.

FAQ – Purchasing Pain Points

Q1. Is P550086 the right filter for my truck engine?
Give us the truck brand, engine model or the OE number on the old filter. We check thread size, gasket diameter, overall height and bypass setting, then confirm in writing before you pay.

Q2. Can you support mixed orders with other filters and small trial quantities?
Yes. MOQ is 50 pieces per number, samples are available for bench testing, and we can load oil, fuel, air and hydraulic filters in one container to reduce freight cost per unit.

Q3. What happens if a batch does not match the sample?
Every order is produced with the same media and gasket supplier and shipped with a batch code. If a confirmed specification is not met, we replace the affected quantity – the batch code lets us trace the exact production run.
