The Therm heater tailpiece is designed for compatible heater plumbing applications that use a 3 inch male buttress thread by 1 inch slip connection in a 90 degree configuration. Tailpieces like this are useful because they help preserve a serviceable heater connection while allowing the rigid plumbing line to turn in a more compact direction.

This replacement is especially useful when the original tailpiece is cracked, worn, or damaged during heater service. The slip connection is well suited to rigid plumbing runs, while the 90 degree orientation helps simplify routing in tighter equipment spaces.

It is a practical service part when restoring a clean right-angle heater connection is part of the repair plan.
