How to Choose Quick Disconnect Couplers

Author: hostarticles | Posted: 21.05.2012

The selection of quick disconnect couplers depends upon its application. The choice of best disconnects will ensure durability and safety of the device for a longer period of time. In this article we are going to discuss some important criterion that must be considered before choosing best quick disconnects coupler.

Temperature: The temperature that the coupling will face while in use. The material of the coupler must be selected depending upon the temperature and the normal temperature range falls between -40° F to 200 °F.

Shutoff requirements: Every application has certain specific requirements and shutoff requirement is one such property. One has to decide that whether one need automatic shutoff valves or that of the integral type. There are different shutoff options available including single-sided, non-spill, and double-sided shutoff valves.

Pressure: Find out the pressure that your coupling has to face while in use. quick disconnects with 250 psi rating are best for low pressure applications. Make sure to consider the maximum pressure rating of the device and the real time pressure that it will be facing while in use.

Tubing options: The size of tubing is another important parameter to be taken care of. Find out the inner and outer diameter and check the compatibility of media that you are planning to use.

Media: The nature of media is also important in the overall process. You need to consider the corrosiveness and viscosity of the fluid that flows around the overall system. The media should be compatible with the chemical composition of quick disconnect couplers.

Flow: Every application requires different flow rate and you must be aware of the GPM (Gallons Per Minute) required for that particular application. Consider other important factors like tubing connections and shutoff valves used in the system.
