Question by: Janice M on Sep 11, 2025, 6:36 AM
What size drill bit does this fitting take?
Answer by: Customer Support on Sep 13, 2025, 6:31 AM
The fitting uses a 0.609 inch drill size on both ends, which helps ensure consistent performance across different setups.
Question by: Brett B on Mar 13, 2026, 11:26 AM
what's the tube OD on this fitting, and will it work with 3/4 inch tubing in a hydraulic line?
Answer by: Customer Support on Mar 15, 2026, 10:08 AM
the tube outer diameter on this one is 3/4 inch, so it's built to connect directly into a 3/4 inch tube line. The A-side thread is 1-3/16-12 and the B-side runs 1-5/16-12, which is your standard male O-ring boss configuration on that end. Both drill sizes come in at 0.609 inches across both ports, so flow passage stays consistent end to end. Overall length is 1.958 inches with a 1.500 inch hex for wrenching, which gives you solid purchase when torquing it down into place.
