This OEM‑standard arm cylinder seal kit is specially designed for mainstream Volvo 24‑30‑ton excavator models:
Volvo Excavators: EC240B, EC240C, EC250D, EC250E, EC290B, EC290C
Special‑Purpose Equipment: Compatible with wheeled excavators and modified heavy‑duty crawler excavators with matching arm cylinder dimensions
High‑Pressure‑Resistant Premium Material: High‑hardness PU + oil‑resistant NBR composite material maintains stable sealing performance under long‑term 400‑bar high‑pressure impact, resisting hydraulic‑pressure deformation.
Heavy‑Duty Wear‑Resistant Structure: Built‑in buffer seals and dust‑proof wipers block external sand, dust and impurities, reducing seal abrasion and extending service life in mining and harsh construction environments.
Wide‑Temperature‑Range Stability: Excellent high‑temperature resistance and low‑temperature flexibility, avoiding seal hardening, aging or softening during long‑hour continuous operation.
1:1 OEM‑Precision Dimensions: Strictly manufactured according to Volvo original‑spec sizes, perfect fit for piston and rod assemblies, eliminating cylinder creeping and digging‑power loss caused by poor sealing.
