Question by: Wade S on Nov 28, 2025, 6:43 PM
trying to swap out a tee on my hydraulic line, is this one 3/4-16 on all three ends or just the run?
Answer by: Customer Support on Nov 30, 2025, 9:55 AM
All three ports are 3/4-16 male ends on this tee. The run and the branch are the same thread size, and it’s a straight thread O-ring boss branch to a JIC 37 degree flare run configuration.
