Product details
This is the Raypak 018758F, the UG bypass assembly kit listed for 336-408 models. UG is Raypak shorthand for underground, matching the underground bypass assembly kits in the same part family.
Ordered as a kit
Bypass work goes badly when pieces arrive one at a time and a fitting turns out to be the wrong size for the next one. Raypak kits the assembly under a single number so the parts come matched to each other.
Check the model range
This kit is catalogued for 336-408. Heater bypass hardware is sized to the heater, so read the model off the data plate before ordering rather than going by physical appearance. If your heater falls outside that range, Raypak lists other bypass kits for it.
