A split nut helps secure and tighten a compatible pump union connection, and this Magic Plastics version is a 2-1/2 inch model using the 0121109025 reference. Split nuts are useful because union-style plumbing depends on the correct nut to maintain a serviceable but secure connection.

This part has practical value because the larger 2-1/2 inch format makes it especially relevant in larger compatible pump plumbing arrangements. A properly selected Magic Plastics split nut contributes to more dependable union retention and more accurate plumbing service.

This type of part is especially useful when the original nut is cracked, stripped, missing, or no longer tightening correctly around the union body. That helps restore the serviceable connection without replacing the whole union assembly.

Installed in the proper application, this split nut helps support dependable union performance and stronger long-term service confidence.

  • 2-1/2 inch pump union split nut from Magic Plastics
  • Helps secure compatible serviceable pump union connections
  • Useful when replacing a damaged or missing original nut
  • Supports dependable plumbing retention and service access
  • Improves replacement confidence and long-term usability
