Improved installation efficiency using an open-ended wrench

TOYOCONNECTOR coupling installation was performed using an adjustable wrench. Because adjustable wrenches tend to be loose and slip easily, installation took a lot of time. Moreover, the hexagonal cap nut could only be grabbed from the side, making installation difficult in narrow spaces.

We decided to use TOYOCONNECTOR LIGHT couplings, which allow open-ended wrenches to be used for installing. The hexagonal cap nut is designed for use with JIS-standard wrenches, making it easier to tighten the cap nut with a more secure fit. Open-ended wrenches can also be used to grab the nut at a 45-degree angle for easier installation in narrow spaces and increased efficiency.
