Sourcing Guide
Identify OTX TO 7099 by its pleated cartridge, two end faces, recorded dimensions and references 200V05504-0108 and 51.05504-0108 before requesting a replacement.
A request for a HOWO T7H oil filter should first identify which item is needed: the replaceable filter element or a larger housing assembly. OTX TO 7099 is shown as a pleated cartridge element, with exposed cream-coloured filter media and dark end caps. It is visually different from a metal spin-on filter. Sending a photograph of only the outside of the installed housing may therefore leave the actual replacement item unclear.
The TO 7099 oil-filter listing provides a useful starting point for enquiries. For this specific code, the OTX catalog records a HOWO T7H application and the reference numbers 200V05504-0108 and 51.05504-0108. Keep those references together with photographs of the removed element; the truck name alone does not establish compatibility with every engine and housing configuration.
| Identification item | Recorded information | What to confirm |
|---|---|---|
| Catalog code | OTX TO 7099 | Use the complete code on the enquiry and quotation. |
| Application named | Sinotruk HOWO T7H | Confirm the actual engine and filter-housing configuration. |
| Reference numbers | 200V05504-0108; 51.05504-0108 | Compare with the old element, packaging or vehicle parts record. |
| Body dimensions | Diameter 121 mm × height 206 mm | Compare the old element using clearly photographed measurement points. |
| Additional diameter marks | Φ52 and Φ14.3 | The catalog block does not label their positions. Request a drawing or sample comparison before assigning them to a particular opening. |
| Visible construction | Pleated cartridge with dark circular end caps | Compare both end faces, the central opening and any locating features. |
Source: OTX filter catalog, page 21, TO 7099 entry. These are identification details, not a complete engineering specification. No filtration rating, service interval, pressure rating or guaranteed cross-brand interchange is established by this catalog block.
A side view establishes the cartridge format and general proportions, but it does not show all the features needed for comparison. The source image includes a broad central opening in an end view and small projecting features visible above the opposite end in the side view. A replacement request should show those details clearly rather than relying on the colour of the paper or the apparent height of the cylinder.
Prepare three separate photographs: one full side view, one straight-on view of each end. Keep the full edge of the end cap in frame and avoid deep shadows over the opening. If an end has a projection or a recessed surface, add an oblique close-up. Photograph loose seals separately, if present, and state whether they came from the element or the housing. Do not assume that every visible seal is included with the replacement.
The recorded 121 × 206 mm body size helps narrow the comparison. Measure across the cylindrical element and record the overall height, explaining whether any protruding features are included. A ruler or caliper should be visible in the photograph so the supplier can understand where the measurement was taken. A damaged or distorted used element may not retain its original dimensions, so report any obvious deformation with the measurement.
The two smaller figures, Φ52 and Φ14.3, are diameter marks rather than a thread designation. Their exact measurement positions are not identified in the catalog block. Do not turn these numbers into a guessed mounting thread, or label one as the top opening without evidence. Ask for a dimensioned drawing or compare a sample when these features determine the match.
An element-only order is different from an order for a housing, cap or complete service kit. State the required scope explicitly. For example, an enquiry can ask for TO 7099 elements and request confirmation of any supplied sealing rings. If a cap or housing component is also needed, give it a separate line with its own photograph and reference.
This avoids an otherwise common ambiguity: the buyer sends a picture of an entire assembly while the quote covers only the cartridge. Before approving the order, check that the description, quantity, photographs and included accessories all describe the same item. Installation procedures, tightening values and replacement intervals should come from the applicable vehicle or engine service information.
TO 7099 appears alongside other oil-filter codes in the wider listing. That proximity does not make those elements alternatives for the same HOWO T7H. Each code has its own reference and application information. In particular, the HOWO T7H identification discussed here belongs to TO 7099; it should not be applied automatically to TO 7102, TO 7105, TO 7107 or TO 7109.
For a mixed fleet, keep every oil-filter reference on a separate order line. You can source other truck oil filters in the same shipment while retaining a distinct vehicle record and sample photograph for each item. The same principle applies when adding fuel filters to a maintenance order.
For several maintenance items, use a mixed truck-parts purchase list with a separate reference and quantity for each line. This supports consolidated sourcing without losing the information needed to match individual parts.
Send your TO 7099 enquiry with the old-part photographs and part list. We can review the available identification details and clarify the requested supply scope before quotation.
The cover and scene image are AI-generated product illustrations based on the catalog reference. They do not document an actual shipment, facility or fitment test.

Part number, truck brand, model, engine model, chassis number and old-part photos help confirm the correct replacement before quotation.
Filters, brake parts, clutch parts, chassis parts, cab parts, bearings, sensors and assemblies can be checked together for one practical order.
Share quantity, packing preference and whether the order is for fleet repair, workshop use or distributor stock.
Send part numbers, truck models, chassis numbers, old-part photos or sample photos. We can help check multiple items and combine them into a practical export order.
