What is the hose length range for Hitachi ZX600LC?

Based on published records with valid lengths, the range is 230–10,000 mm. Open the individual record to verify its installation position and both end fittings before fabrication.

Which hose specifications are common for Hitachi ZX600LC?

The most frequent raw specifications in the current published records are: DN10;1SN-6;7Mpa (11 records), DN10;1SN-06;18MPa (9 records), DN6;1SN-04;22.5MPa (9 records), DN6;2层纤维-4;14MPa (6 records), DN6;1SN-4;7Mpa (5 records). Verify the specification together with length, pressure, and fitting details.

How can I identify the left and right hose fittings for Hitachi ZX600LC?

Each record keeps the left and right fitting descriptions separate. Current examples: 4436685: left 美制内螺纹37°内锥; right 美制内螺纹37°内锥; 4379172: left 美制内螺纹37°内锥; right 美制内螺纹37°内锥; 4227025: left 美制内螺纹37°内锥; right 美制内螺纹37°内锥. Open the exact part-number or pipe-number record; do not swap ends based on appearance alone.

Can I locate a Hitachi ZX600LC hose by diagram pipe number?

Yes. Current examples with a diagram pipe number are: Pipe No. 7 (4436685), Pipe No. 7 (4379172), Pipe No. 23 (4227025), Pipe No. 6 (4453966). Open a record to compare its installation position with the linked manual page.
