Includes our printed Thread ID Booklet

The first step in understanding hydraulic fluid fittings is identifying your existing fluid ports and connectors.
Nominal sizes and dash sizes are often different from actual thread dimensions, leading to potential confusion for users who aren't familiar with the standard sizing conventions for fluid ports and connections.
Whether your fluid powered equipment is old or now, imported or made in America, our guide "How to Identify Fluid Ports and Connectors" will help you to find the correct fittings, adapters and hose ends to keep your equipment running.
