OUR Services



New Items Hook Industrial Sales produces new, top quality cylinders with the best possible configurations in the industry. Pistons, which are bronzed, and glands have H-packs and G-rings. Rods and tubes are honed and chromed when needed. Mill type are standard heavy duty and durable to protect the inner workings of cylinders. Our cylinders are custom-made to our client’s specifications so they can be retrofit to existing mounting and porting locations.


Hook Industrial Sales backs the rebuilding of your hydraulic or pneumatic cylinder with more than fifty years of experience. We rebuild cylinders to the original specifications using identical OEM replacement parts. When rebuilding components not up to current industry standards, H.I.S. will upgrade to the highest industry specifications. H.I.S. utilizes the expertise of one machinist throughout the entire process of rebuilding each cylinder. This policy optimizes the craftsmanship of our employees while assuring that each cylinder will have a proper fit. The rebuild process begins with a complete disassembly and thorough cleaning of each part. Before completion, each cylinder undergoes “dry assembly,” final assembly, testing, and a minimum of two inspections to guarantee fit and function.
