Based on current published data

Common Repair Questions

Questions appear only when a published record or linked PDF page provides the answer.

How many hoses are currently listed for Hitachi ZX350LC-3 Attachments?

There are 6 published records. 6 include a length, both end fittings, and a part number or diagram pipe number.

What is the hose length range for Hitachi ZX350LC-3 Attachments?

Based on published records with valid lengths, the range is 350–1,800 mm. Open the individual record to verify its installation position and both end fittings before fabrication.

Which hose specifications are common for Hitachi ZX350LC-3 Attachments?

The most frequent raw specifications in the current published records are: DN6;1SN-04;22.5MPa (3 records), DN10;1SN-6;7Mpa (1 records), DN19;1SN-12;7Mpa (1 records), DN6;1SN-4;7Mpa (1 records). Verify the specification together with length, pressure, and fitting details.

How can I identify the left and right hose fittings for Hitachi ZX350LC-3 Attachments?

Each record keeps the left and right fitting descriptions separate. Current examples: 4669454: left 美制内螺纹37°内锥; right 美制内螺纹37°内锥; 4642723: left 美制内螺纹37°内锥; right 90°美制内螺纹37°内锥; 4451995: left 美制内螺纹74°内锥; right 美制内螺纹74°内锥. Open the exact part-number or pipe-number record; do not swap ends based on appearance alone.

Can I locate a Hitachi ZX350LC-3 Attachments hose by diagram pipe number?

Yes. Current examples with a diagram pipe number are: Pipe No. 5A (4669454), Pipe No. 19 (4642723), Pipe No. 43 (4451995), Pipe No. 204 (4437902). Open a record to compare its installation position with the linked manual page.
