About this union/fitting

This Magic Plastics 1-1/2" pump union connects your spa pump to the plumbing system with industry-standard threaded connections. The slip x female buttress thread configuration provides a secure, leak-free seal for most residential spa and hot tub pump installations. Built to exact OEM specifications, this union handles the water flow and pressure demands of typical spa circulation systems.

At Bubbles Supply, we guarantee this pump union will fit your application perfectly or we'll make it right. Every Magic Plastics union ships the same day you order and comes backed by our comprehensive 1-year warranty. Before installation, verify your existing pump union dimensions match the 1-1/2" slip and female buttress thread specifications to ensure proper fitment.

Common symptoms this part fixes

If your spa is showing any of these signs, this part is likely your fix:

  • Active leak at pump inlet or outlet connection
  • Union cracked or visibly damaged from freeze or overtightening
  • Threads stripped and union won't seal
  • Union body warped or deformed from heat or UV exposure
  • Slow drip that worsens under pump pressure

Not sure if this is your problem? Try our diagnostic centre or .

Before you buy — quick checklist

  • Confirm your existing union is 1-1/2" slip on the plumbing side — measure the pipe OD, not the fitting ID
  • Verify the pump body side is female buttress thread (FBT), not NPT or barb — buttress threads have a distinctive asymmetric profile
  • Check whether you need to replace just the union half or the full union assembly including both halves and the o-ring
  • Inspect the existing o-ring groove condition on your pump volute — a damaged groove will still leak even with a new union
  • Match the Magic Plastics 0602-15 against your current union's part number or branded markings before ordering

Reading the checklist now prevents 90% of returns. Worth the 60 seconds.
