Specs At A Glance

Good To Know

Q: Will these couplers work with my existing air plugs? A: They are built to the common 1/4 inch industrial interchange profile, so they mate with standard plugs of that size. Check your plug style before ordering if your system uses a specialty profile.

Q: Do I need thread sealant when installing them? A: Yes, wrapping the NPT threads with PTFE tape or applying pipe sealant helps prevent air leaks at the joint. Tighten snugly without overtightening the fitting body.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
