Split Nut 2-1/2" PVC – 4" OD Heater & Plumbing Retaining Nut

Secure large-diameter plumbing connections with the 2-1/2" PVC Split Nut (4" Outside Diameter), designed for pool and spa heater manifolds and high-flow plumbing assemblies. This split-style retaining nut allows secure fastening around unions and manifolds without requiring full disassembly of rigid plumbing—making service and repairs faster and more efficient.

Split nuts are commonly used in heater and manifold applications where frequent maintenance may be required. Over time, exposure to heat, pressure, and vibration can cause cracking or loss of clamping force. Replacing a worn split nut restores proper compression, helps prevent leaks, and ensures stable alignment of connected components.

Manufactured from durable PVC, this split nut is suitable for chemically treated water environments and is ideal for heater plumbing, manifold connections, and large-format spa or pool plumbing systems.
