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

How many hoses are currently listed for Hitachi ZX850LC-3 Grease Lines?

There are 28 published records. 28 include a length, both end fittings, and a part number or diagram pipe number.

What is the hose length range for Hitachi ZX850LC-3 Grease Lines?

Based on published records with valid lengths, the range is 300–3,900 mm. Open the individual record to verify its installation position and both end fittings before fabrication.

Which hose specifications are common for Hitachi ZX850LC-3 Grease Lines?

The most frequent raw specifications in the current published records are: DN5;2层纤维-3;14MPa (9 records), DN6;2层纤维-4;14MPa (6 records), DN6;1SN-04;22.5MPa (4 records), DN6;1SN-4;7Mpa (3 records), DN6;1SN-4;10.5MPa (2 records). Verify the specification together with length, pressure, and fitting details.

How can I identify the left and right hose fittings for Hitachi ZX850LC-3 Grease Lines?

Each record keeps the left and right fitting descriptions separate. Current examples: 4367714: left 英制内螺纹30°外锥; right 英制内螺纹30°外锥; 4656502: left 美制内螺纹37°内锥; right 公制卡套式; 4656501: left 美制内螺纹37°内锥; right 公制卡套式. Open the exact part-number or pipe-number record; do not swap ends based on appearance alone.

Can I locate a Hitachi ZX850LC-3 Grease Lines hose by diagram pipe number?

Yes. Current examples with a diagram pipe number are: Pipe No. 19 (4367714), Pipe No. 6 (4656502), Pipe No. 5 (4656501), Pipe No. 1 (4258880). Open a record to compare its installation position with the linked manual page.
