Shamrock Hose and Fittings was founded near Cleveland by industry vet Don O’Shaughnessy. Quickly gaining trust as a Parker distributor, they outgrew their first location and moved. In ’87, they doubled their warehouse size. Tim O’Shaughnessy took over in ’95 and opened a second location in 2015. Today, they stock 9000+ part numbers from top manufacturers and are known for great customer service and technical support.
