Hydraulic Quick Couplers

Hydraulic quick couplers facilitate the quick connection and disconnection of fluid lines in a quick and convenient way.

Learn how to identify the various types of quick coupler fittings and hydraulic threads including the most common NPT thread and others such as SAE, BSPP, JIC, ORFS and others.

Hydraulic systems are what keep heavy machinery running and getting the job done. They provide the power behind many critical functions, and when something goes wrong, safety can quickly become an issue. That’s why understanding working pressure and burst pressure ratings is so important. In this guide, we’ll break down pressure ratings in a simple, easy-to-understand way to help you choose the right hydraulic components and keep your system running safely and reliably.

ISO 7241:2014 defines the performance and dimensional requirements for both Series A and Series B hydraulic quick couplings.

Flat-face hydraulic quick couplers are designed to reduce leakage and help protect workers from high-pressure hydraulic fluid dangers.
