Question by: Shawn T on May 6, 2025, 8:07 PM
Will this tee fitting work if I need to adapt from a O-ring face seal to a O-ring boss setup?
Answer by: Customer Support on May 8, 2025, 6:52 AM
That's precisely what this adapter is designed for. It allows you to connect a 1-11/16-12 Male SAE O-Ring Face Seal on the run and branch to a 1-5/8-12 Male SAE O-Ring Boss on the other run.
