The Hydro-Quip 90 degree heater tailpiece is designed for compatible heater applications where a 2 inch MBT to 3/4 inch barbed connection is needed. A tailpiece like this is useful because it helps create a clean heater-side transition while also accommodating a right-angle change in plumbing direction.

This replacement is especially useful when the original fitting is cracked, leaking, or when the supported installation depends on this exact thread-and-barb combination. Matching the correct tailpiece helps reduce plumbing compromise and supports a cleaner final repair.

The 42-2391-K is a practical service fitting when a compatible Hydro-Quip heater setup needs a 90 degree 2 inch MBT to 3/4 inch barb tailpiece for dependable connection support.

  • 2 inch MBT by 3/4 inch barb configuration
  • Designed for compatible heater-side plumbing transitions
