Alocs 2-Inch Spa Heater Union Nut Kit for Balboa Gecko – Gasket & O-Rings Included

Overview

Keep your spa connections solid with the Alocs 2-Inch Spa Heater Union Nut Kit. This thoughtfully assembled kit is designed for Balboa 2" heater assemblies and is compatible with Gecko systems, offering a practical solution for securing the heater-pump union and preserving flow. The set emphasizes durable components and straightforward installation, giving you a clear path to address leaks and loose fittings without downtime.

What you gain is a complete, ready-to-use bundle that emphasizes reliable seals, easy handling, and real‑world practicality. The kit focuses on common hot tub repair scenarios, helping you move from a leak worry to a confident, measured repair plan.

What’s Included

• Two 2-inch heater split nuts, designed to fit standard spa unions with a 2" heater tube
• Two replacement gaskets to establish a secure, leak‑resistant seal
• Four screws to anchor the nut and secure the connection

Compatibility and Use

• Designed for Balboa 2" heater assemblies with an actual 3" nut size; also suitable for Gecko, Coleman, HydroQuip, Spa Builders, Correctech, and Spanet systems
• Not compatible with Coleman Saluspa and LX Heater series

Installation Tips

To install, remove the old broken pump union flange nut. If the nut is severely split, it can be cut away with a hacksaw or cutting pliers, taking care not to damage the pump union body. Position the new split nut, insert the gasket, align with the flange, and tighten the screws until the connection feels secure. The gasket and nuts work together to create a watertight seal while keeping debris out of the system.

Why This Kit Works in Real Life
