Question by: Terry P on Nov 13, 2025, 1:35 PM
So this fitting has two different tube OD sizes, a 3/4" and a 1/2"? Just want to make sure I'm understanding that right.
Answer by: Customer Support on Nov 15, 2025, 6:04 AM
Yes, that's correct. This straight fitting is designed to accommodate both a 3/4" tube OD on one end and a 1/2" tube OD on the other, making it useful for connecting different sized lines.
