Overview

AFZZ presents a reliable replacement option for spa heater unions. The Spa Heater Split Nut Union is designed for common 2-inch heater assemblies and ships with a gasket and screws, delivering a solid, secure feel when reassembling hot tub connections. This part is crafted to support steady water flow and a stable seal, making routine maintenance or quick repairs easier for premium spa systems.

Compatibility and Fit

This split nut union is built for Balboa heater assemblies and is compatible with a range of brands, including Gecko, Coleman, HydroQuip, Spa Builders, Correctech, and Spanet. Please note that it is not suitable for Coleman Saluspa or LX heater series, and it is not intended for inflatable hot tubs. Correct sizing and sealing are essential for a leak-free connection.

What’s Included

  • Split nut union body
  • 2-inch heater gasket
  • Screws for fastening

Key Specifications and Fit Notes

  • Outer diameter: ≈ 3 3/8 inches
  • Inner diameter: ≈ 2 3/4 inches
  • Thread: 2" MBT buttress thread (standard for many heater assemblies)

Installation Tips

  • Avoid matching the pipe size to prevent an overly tight fit.
  • Use the included gasket and two screws to secure the union to the pump threads.
  • Tighten carefully with a screwdriver to achieve a snug, leak‑resistant seal without over-tightening.

In everyday spa care, this AFZZ component supports straightforward maintenance by offering a speedy path to replace a worn or damaged heater nut union. The combination of a solid nut, a precision gasket, and the required screws helps deliver a dependable connection once installed.
