Frequently Asked Questions
Does the 5 mm port accept 3/16 in. tubing?
No. 5 mm (about 0.197 in.) and 3/16 in. (0.1875 in.) OD are not interchangeable; use true 5 mm OD tubing.
What thread is on the male end?
A 1/4 in. global thread that seats on tapered or O-ring ports common on metric equipment.
Can I reuse the fitting after disconnecting?
Yes. Push-to-connect collets release and re-grip the tube; inspect the tube end for nicks before reinserting.
