Given a pneumatic utilizing 1 direction functionality, is it required to have a fitting in the end of the pneumatic with 1/8" tubing in the fitting for the end of the pneumatic that is only dumping to the atmosphere? Or can we take out the fitting because we are not connecting it to anything?
When components are to be connected, the 1/8 " tubing must be used.
If the component is not supplying and is venting it can be done to atmosphere.
Note several styles of cylinders have this feature built in.
