Overview

When a spa heater union starts to leak or lose a solid seal, the Alocs 2-Inch Spa Heater Split Nut Union offers a practical, non-invasive repair option. Designed for 2-inch heater assemblies, the unit features an outside diameter of about 3.35 inches and an inner bore close to 2.30 inches, providing a sturdy platform for a reliable seal. It’s built to fit a range of popular brands, including Balboa, Gecko, and HydroQuip, helping you tackle common repair scenarios without a full pipe replacement.

The assembly is crafted for quick, tool-friendly replacement. A gasket sits between the heater flange and the union, creating a barrier to leaks and debris while keeping the connection tight during operation. The kit is purposefully sized to support emergency repairs with minimal disruption to your spa routine.

Durability and materials

Durable construction handles regular hot water exposure and typical spa chemical environments. Rubber gaskets are designed to maintain flexibility over time, helping to sustain a secure seal even after multiple removal and re-installations.

Key benefits

  • Fast, screwdriver-friendly installation that avoids cutting PVC piping
  • Leakproof gasket seal minimizes drips and debris entry between the union and heater
  • Comes as a complete repair kit with 2 split nuts, 2 gaskets, and 4 screws
  • Broad compatibility across Balboa, Gecko, and HydroQuip heater systems for versatile use

Compatibility and installation tips

Use with most 2-inch heater assemblies, typically found on spa heaters around 15 inches in size. Not suitable for inflatable hot tubs. Also note it is not compatible with Coleman Saluspa and LX heater series. Verify your pump body flange and thread arrangement before purchase.

What’s included

  • 2 x heater split nuts

Notes

Designed for 2-inch heater unions and intended as a practical replacement option to restore a secure seal and reduce maintenance interruptions. Color is black for a discreet, low-profile installation.
