Product Questions & Answers

what size tube does this cap assembly fit onto?

Question by: Neal H on Dec 9, 2025, 9:45 PM

Built around a 3/4 inch tube O.D., so if your line matches that outside diameter, this cap assembly should seat up right. The hex comes in at 1.375 inches, which gives you a solid wrench flat to work with during installation.
