HW Part Store carries a focused line of hydraulic cylinder seal kits for Case mini excavators across multiple models, including the Case CX25, CX27B, CX31, CX31B, and CX36, with these kits maintained in stock for quick availability.
The line focuses on Case construction equipment parts used in hydraulic cylinder repair. Each kit is matched to a specific cylinder location and machine model, so customers can source exact-fitting replacement parts rather than sorting through generic options.
Â
The seal kit selection for Case mini excavators covers the primary hydraulic cylinder types found across these models: boom, arm, bucket, swing, and blade. Having the correct seal kit parts available reduces the time lost when a hydraulic cylinder begins to leak on the worksite, supporting faster repairs and less unplanned equipment downtime.
Each kit is matched by rod diameter, bore size, cylinder number, and serial number range where applicable, so the parts correspond directly to the cylinder being repaired.
This level of specificity removes the guesswork from sourcing case parts and related construction equipment parts for hydraulic cylinder maintenance.
For the Case CX25, seal kits are available for the swing, blade, boom, and arm cylinders. The Case CX27B offers five cylinder-specific kits with rod and bore dimensions such as 40 mm rod and 70 mm bore for the boom and arm, a 35 mm rod and 60 mm bore for the bucket, and a 45 mm rod and 85 mm bore for blade cylinders.
Each aftermarket replacement kit is selected to match the hydraulic cylinder dimensions and application for a defined Case machine model and cylinder number. Components such as seals, wipers, and piston wear rings correspond directly to the original rod and bore measurements.
Because the Case equipment parts are matched to those specifications, they fit and function as intended without modification.
For customers uncertain which cylinder a kit corresponds to, the Excavator Cylinder ID Diagram helps identify common cylinder positions on Case excavators, including boom, arm, bucket, swing, and blade cylinders.
HW Part Store has more than three decades of hands-on hydraulic cylinder experience in identifying and supplying the correct Case equipment parts.
We categorize mini excavator parts by model, cylinder number, and dimensional specifications, reducing the likelihood of ordering Case parts that do not correspond to the cylinder being serviced.
