- Automated packaging machine air distribution
Installation protocol:
Apply 2-3 drops of pneumatic sealant (Loctite 577 recommended) on male threads.
Tighten to 12-15 N·m torque using crowfoot wrench. Avoid overtightening - maximum
1/4 turn past finger-tight. Perform pressure test at 1.25× system pressure before
commissioning.
