Description
This complete heater connection kit features a 2" heater flange split nut with approximately 3" inner diameter, accompanied by a gasket and (2) mounting screws designed for 2" heater unions that measure roughly 3" edge to edge on the threaded portion. The split nut component fastens directly to your heater tube using the included pair of screws, creating a secure mount that threads onto the heater union with the gasket positioned between the union and tube assembly. This kit is appropriate when both your spa plumbing and heater connections are 2" specifications.
Among heater union kits, this 2" x 2" configuration represents the highest volume choice for hot tub installations, with 1 1/2" x 1 1/2" being the second choice and 1 1/2" x 2" ranking third in popularity. These components establish the critical connection between your spa's heater tube and heater union assembly. Please note: Heater tube shown in product imagery is for demonstration purposes only and is not included with this kit.
