Overview

Discover the Magic Plastics 0121109020 split nut, a purpose-built component for spa and hot tub pump unions. Sized for 2-in connections with an approximate inner diameter of 3 1/16 in, this part is designed to help you maintain secure, dependable fittings in damp environments.

What it fits

Designed for pump unions with a 2-in to 2-3/4-in diameter range on both ends. It features a female buttress thread (FBT) and a small flange for a tidy, low-profile connection.

Installation and maintenance

  • Two compatible connection sizes: 2 in and 2-3/4 in on each side
  • Female buttress thread with a small flange for a secure, compact fit
  • Black finish compatible with standard spa hardware

Practical use cases include routine filter changes, pump servicing, or replacing worn hardware in spa and hot tub setups. The part is designed to perform in wet, high-humidity environments while maintaining a clean, professional appearance.

Why choose this split nut

  • Replaces worn or missing split nuts to restore a reliable seal
  • Designed for quick reassembly, minimizing downtime
  • Compact, unobtrusive footprint that fits tight pump bays

Note: Verify your exact thread type and flange specification before replacement. This part is intended for spa and hot tub pump unions and should be used with compatible fittings.
