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.

Improved installation efficiency using an open-ended wrench
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.
