A quick disconnect coupling accelerates the detaching of hydraulic lines.
Quick Disconnect Applications
When a job requires repeated disconnection and reconnection of a hydraulic line, rapid disconnection increases productivity. For the testing of hydraulic components, couplings that disconnect quickly are more efficient than using a fitting and wrench. Choosing the right quick disconnect coupling for your application requires some thought.
Fluid Temperature
The temperature of the hydraulic fluid is a factor when selecting a coupling. Take into account the rate of flow and line pressure.
Durability
Will the quick disconnect coupling have to hold up under potentially damaging conditions? Will the connector or hydraulic line be subject to impact, corrosives, or extreme heat? Will it need to withstand excessive vibration?
Line Diameter
Determine the diameter of the hydraulic line to which the connector will be attached and the line material. How often will the connector be engaged and disengaged?
Coupling Type
Does your connector need a valve? Should it be a single or double valve configuration? A valve limits fluid loss, but the fluid pressure tends to fluctuate. What type of mechanism for engaging/disengaging the connector? For hydraulic applications, a flat-face coupling reduces fluid loss during uncoupling and reduces the risk of fluid contamination.
Material
Should you choose aluminum, brass, plastic, stainless, or steel coupling? A plastic coupling could contain metal that is compromised by hydraulic fluid.
Pressure Rating
Choosing the right pressure rating extends the life of the coupling. Also, take the rate of pressure loss into account.
