The short stud on either end of the globe vavle is 1.7 mm dia. This fits the 1.8 mm ID of Evergreen 1/8" tubing (#224, #424).
This should fit without problems but be aware that the O.D. and I.D. of Evergreen tubing is 'nominal' and may vary by a few thousands of an inch. I suggest that if the valve does not easily slip into the tubing that you ream the tubing with the appropriate size drill as the valves are made of FUD/FXD and will break before the styrene does.
