As well as being the sole Australian holder of the Germanischer Lloyd welding shop approval, we have American Bureau of Shipping Type Approval on several designs of heavy duty Ride Control System actuators, and recently successfully completed our Manufacturing Assessment Certification. We have also previously worked on many occasions with other global marine classification societies such as Det Norske Veritas and Lloyds Register of Shipping, having many cylinder designs and welding procedures approved, making us arguably the most qualified marine cylinder manufacturer in Australia.

If you require any further information on our Company or how we can service your hydraulic cylinder needs, please feel free to contact us.


Ezy-Fit Marine has modern state of the art facilities which include CAD/CAM design and production technology for accuracy of drawings, components and finished product. 

We use the latest in CNC lathes and machine centres, saws and honing equipment. Our engine lathes allow us to machine up to 12 metres in length with up to a 1250mm swing. 

We are highly capable in the welding of ferrous and stainless steels for which we have certified procedures and personnel, and have MIG, TIG and Oxy-Acetylene equipment. 

All welds are non-destructive tested to varying degrees depending on the class requirements.

Positioning Sensors

We are able to fit positioning sensors to most cylinders, including internal and externally mounted profile type Linear Displacement Transducers.  Stroke range is 10mm to in excess of 6000mm.


We can custom design various types of valving requirements to complement your cylinder design and circuit requirements.  All valve blocks are manufactured in house to exacting standards on CAD/CAM multi-axis machine centres and many different cavity tools exist in our store to suit your valve cartridge brand and flow rate needs. 

Valve blocks can be remote mounted and hard piped or welded directly to the cylinder or piston rod end.  In-line end cap mounted and piggy-back mounted, among other mounting styles, can be achieved.  Welding the valve block directly to the barrel rather than remote mounting eliminates potential leak points, and enhances the strength and reliability of the cylinder.  All tube lines can be permanently welded or fitted with removable threaded connections for ease of service work.


Cushions of several types can be designed into suitable cylinders and include fixed and adjustable, spear type, piccollo and occluded port type.
