Questions and answers of the customers

  1. Q Looking at it, it says max temp of 200 F, but if I click on the link for the glass specs in the description it says the glass is rated for 450 F. Is the lower limit because of the seals used during assembly, and if so do you make custom ones with PTFE seals, or some other seal that can go up to 450 F ?
    A The rating of 200-Degrees is for the union, not just the glass itself. Unfortunately, we do not rate any clamp union at 400 degrees Fahrenheit.
