The Waterway 415-4021 heater split nut is designed for compatible 1-1/2 inch heater applications and includes screws, with a short buttress thread design. A split nut like this is useful because it helps secure the connection while allowing the assembly to be serviced more easily than a permanently joined fitting.
The included screws make this Waterway part more convenient as a repair kit, while the short buttress thread format helps maintain correct compatibility with the intended heater connection style. Using the right split nut can restore both fit confidence and serviceability at the connection point.
For compatible heater plumbing service, this Waterway split nut is a practical replacement when a 1-1/2 inch short buttress-thread connection with included screws is required.
