One of our customers were struggling with a lack of space but the need to connect their piping all the same. They reached out to us to see if we could provide a solution for 3 lines to merge at 90°s to each other.  We were able to assist and produced a couple of special 90° elbows with an addition branch.  These happened to be lined with static dissipating PFA.  Over the years we have produced all kinds of special PFA lined fittings like these where the standard range of ASME B16.5 fittings are not suitable.  We would be happy to assist you with your next challenge !
