FAQ

Questions buyers ask about hydraulic cylinders

Can you build a cylinder to replace an existing OEM part?

Yes. Send the cylinder make and model or the OEM part number, plus bore, rod, stroke, working pressure and mounting dimensions. We will confirm interchangeability before quoting.

Are your cylinders 100% tested?

The documented US cylinder project used 100% pressure testing. Pressure, holding and cycling tests, acceptance criteria and records for your order are agreed in its inspection plan.

What is the warranty?

The warranty period, starting date, coverage and exclusions are stated in the quotation and order agreement. Confirm the operating pressure, fluid conditions and installation requirements before ordering.

Do you sell seal kits separately?

Send the cylinder make, model and seal specifications for a separate seal-kit enquiry. Compatibility, stock availability and dispatch timing are confirmed in the quotation.
