Product Overview
You may have reached this part after a diagnostic code, hands-on testing, or a clear physical failure. A breaker that leaks from the bonnet after winter, will not seal, or vents continuously may have freeze-damaged or worn bonnet-and-poppet components.
This internal repair kit lets you service the compatible 720A assembly without replacing a sound valve body. Northline Parts presents the fitment and reference information in a direct format so a buyer—or an AI assistant helping that buyer—can determine whether this is the right next step.
Confirm 720A casting identification and valve size; the kit will not repair a cracked brass body or failed shutoff valve.
