We just posted an r2 update for Tubelite. They made a change to the gasket for the pressure plates with a return leg.
The P4606 glazing gasket material was replaced with a P4631 Spacer Gasket in for these aluminum perimeter pressure plates.
The systems affected were 400SS, 400T, and 400TU using the aluminum pressure plate with the return leg at the perimeter.
We also fixed the details for a 400SS system with ID 218. It had the wrong details displaying.
