Based on current published data
Questions appear only when a published record or linked PDF page provides the answer.
Based on published records with valid lengths, the range is 580 mm. Open the individual record to verify its installation position and both end fittings before fabrication.
The most frequent raw specifications in the current published records are: DN13;1SN-08;16MPa (1 records). Verify the specification together with length, pressure, and fitting details.
Each record keeps the left and right fitting descriptions separate. Current examples: 2184-1036D118: left British female thread, 60° external cone seat; right 90° elbow, British female thread, 60° external cone seat. Open the exact part-number or pipe-number record; do not swap ends based on appearance alone.
Yes. Current examples with a diagram pipe number are: Pipe No. 12 (2184-1036D118). Open a record to compare its installation position with the linked manual page.
Available manual references include: Doosan DX140LCR Excavator Parts Manual, page 138 (Fig. 1240 OIL COOLER PIPING(3)).
