Product Overview

The 707-99-25870 bucket cylinder seal kit is a factory-manufactured aftermarket replacement kit cross-referenced against the Komatsu part number 707-99-25870 (also written 7079925870). Independent aftermarket listings consistently identify the kit as the bucket cylinder seal kit, used on Komatsu PC120-6E0 and PC130-7 excavators, with several resellers additionally cross-referencing it to the bucket cylinder of the PC200-7, PC200LC-7 and PC220LC-7.

DJF Seals manufactures and supplies the 707-99-25870 kit at factory-direct wholesale pricing for Komatsu equipment dealers, repair shops and fleet maintenance programs.

Verified Application

The following application data was cross-checked against aftermarket parts listings (eBay, buymachineryparts.com, FridayParts, Prime Machinery Depot, CARTEX/Amazon, deepparts.com, soonparts.com, suncar-seals.com, Alibaba):

Note: the current page title claims PC120-7 and PC130-7; PC130-7 is confirmed by external sources but PC120-7 could not be found in any independent listing (see Fitment Verification). Specific material grades, pressure rating, temperature range, exact piece counts, certifications and service life are factory data and are not independently verified. Verify these details with the factory before ordering.

Replacement Scope

This kit covers the sealing elements required to reseal the bucket cylinder of the verified Komatsu models. Resellers describe the kit for the standard bucket cylinder configuration shared across the PC120-6E0 / PC130-7 family. Exact kit contents and piece counts should be verified with the factory against your cylinder before ordering.

Fitment Verification

The part number, bucket position and fitments were verified through multiple independent sources:

• eBay: “707-99-25870 Bucket Cylinder Seal Kit For Komatsu PC120-6EO” — bucket cylinder position.
• buymachineryparts.com: “Bucket Cylinder Seal Kit 707-99-25870 for Komatsu PC120-6E0 PC130-7 PC200-7” — replacement part numbers 707-99-25870 / 7079925870; fitment includes PC120-6E0, PC120-6E0-T2 and further models.
• FridayParts / Prime Machinery Depot: bucket cylinder seal kit 707-99-25870 for Komatsu PC120-6E0, PC130-7, PC200-7, PC200LC-7, PC220LC-7.
• CARTEX (Amazon): bucket cylinder seal kit 707-99-25870 for Komatsu PC120-6E0, PC130-7, PC200-7.
• deepparts.com / soonparts.com: “707-99-25870 7079925870 for Komatsu Excavator PC120-6 PC130-7 PC200-7” — the “PC120-6” notation is read as the PC120-6E0 family.
• Alibaba: “SEAL BUCKET CYL SEAL KIT for PC120-6EO PC130-7” — bucket cylinder position.
• Conflict note: the current page title and URL claim PC120-7 and PC130-7. PC130-7 is confirmed by multiple independent sources, but PC120-7 could not be found in any independent listing — every third-party source specifies PC120-6E0 (or PC120-6). The PC120-7 fitment is therefore not claimed on this page.
• Conflict note: the current page table also lists PC120-6E0 and PC130-7K; PC130-7K was not found in external sources.
• Conflict note: no independent Komatsu OEM catalog reference was accessible for this part number; the identity and fitments above rely on aftermarket listings.
• Dimension note: deepparts.com/soonparts.com list a 65 mm rod / 95 mm bore for this kit; this is a single supplier’s claim, not independently corroborated, so it is not asserted on this page.
• Materials, pressure, temperature, piece counts, certifications and service life are not independently verified.
