Part number / cross reference
OEM and interchange reference: 4206097 | 4218256 | 4214872
Use the number from your parts book to confirm interchangeability. If your number is not listed, send it to us — we cross-check against the parts manual and confirm in writing before you pay, because a wrong part costs far more in freight and downtime than the part itself.
Compatible machines

Fitment can change on a serial-number break within the same model. Send us the model and serial number from the machine nameplate and we verify it against the parts manual before dispatch.
Why this part fails — and what we do differently
On the Hitachi EX120-1 the hydraulic oil cooler side has to reject the full engine heat load while sitting behind a radiator that is often already partly blocked with dust. We supply to OEM core specification and check fin integrity and joint pressure before shipping, because a pinhole leak here shows up as coolant loss under load, not as a puddle on the floor.
Ordering, packing and warranty
Order quantity is flexible — one piece for a machine that is down, or a full container for your stock. Goods are packed part by part with clear labelling for your stores, and we provide inspection photos plus measured dimensions before the balance payment. Manufacturing-defect warranty 6–12 months.
