Waterway Heater Split Nut – 1-1/2" Replacement Retaining Nut

Secure heater manifold and plumbing connections with the Waterway Heater Split Nut – 1-1/2", designed for use on compatible Waterway spa and pool heater assemblies. This split-style retaining nut allows the manifold connection to be tightened or serviced without removing rigid plumbing, making heater maintenance faster and more efficient.

Heater split nuts are exposed to repeated heat cycling, vibration, and system pressure. Over time, they can crack, strip, or lose clamping strength - leading to leaks or unstable manifold connections. Replacing a worn split nut restores proper compression, helps maintain a watertight seal, and protects the heater manifold and surrounding plumbing from movement or stress.

Manufactured to OEM fit standards, this split nut is designed for use with Waterway heater manifolds and plumbing components. It is ideal for repairs, refurbishments, or preventative maintenance on spa and pool heating systems
