Raypak 005393F – Male Threaded Adapter – R185–R405 Heaters
If the water connection at the heater is leaking, cracked, or no longer threading cleanly into the mating plumbing side, the adapter itself may be the problem. Once a threaded water-side fitting is worn or damaged, tightening harder usually makes the repair worse, not better.
This male threaded adapter is used at the heater water connection on Raypak R185 through R405 heaters. It provides the threaded interface needed to connect compatible plumbing components to the heater. When the original adapter is cracked, cross-threaded, or worn from repeated service, replacing it restores the connection point cleanly.
