Can you reverse engineer a cylinder from a sample?

Yes, reverse engineering is available when an original cylinder sample is supplied.

What testing is performed on each cylinder?

Each cylinder undergoes incoming material inspection, dimensional inspection, weld inspection, rod surface inspection, hydraulic pressure testing, leakage testing and full-stroke functional testing. Final inspection includes 100% checks before shipment.

Do you offer custom paint colors?

Yes, standard color is Komatsu-compatible yellow but customer-specified colors are available.

Can the cylinder be supplied with a holding valve?

Yes, holding valve interfaces are available where required by the original application and confirmed design.
