I have a 1" buried PE gas line that I'd like to tap into for a gas firepit. The gas line supplies a few other things in the yard, notably a 400kbtu pool heater. From research, it seems undersized for this load, so while the heater seems to work OK, my assumption is that I don't want to do anything to further reduce flow.
The easiest DIY approach is to use a compression fitting like this one:
My concern is that it requires stiffeners (white in this picture) be added to the ID of each end of the pipe, which will inherently limit flow a bit. My question is: Is it possible to use this type of compression fitting without a stiffener?
My fallback is to use fusion fittings, which do not reduce the ID but require the rental of a special tool and require some skill to get right.
