About this wet end

The 48Y Frame 2" MBT x 2" MBT Wet End PKUL15HSDCS2-2 is a genuine Vico OEM replacement wet end designed for 1.5HP spa pumps with 48Y frame configuration. This wet end features 2-inch male buttress thread (MBT) inlet and outlet connections, providing reliable water flow for your spa circulation system. Built to Vico's original equipment specifications, this Ultima series wet end delivers the exact hydraulic performance your spa requires.

At Bubbles Supply, we guarantee this wet end will fit your existing 48Y frame pump perfectly, backed by our 1-year warranty and same-day shipping. The precision-molded construction and corrosion-resistant materials ensure long-lasting performance in hot water applications. Before installation, verify your existing pump's frame size and connection threading to confirm compatibility - the 2" MBT fittings should match your current plumbing connections for proper installation.

Common symptoms this part fixes

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

  • Weak or low water flow from jets

  • Wet end leaking at housing seams
  • Noisy pump with grinding or rattling from wet end
  • Loss of prime that persists after troubleshooting
  • Visible housing damage or freeze cracking

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

Before you buy — quick checklist

  • Confirm your existing pump motor is 48Y frame — check the motor label or measure the mounting face bolt pattern
  • Verify your plumbing connections are 2-inch MBT (male buttress thread) — do not assume based on pipe diameter alone
  • Confirm the motor itself is still functional before replacing only the wet end
  • Check the existing impeller and diffuser condition — if severely worn, they may need replacement alongside this wet end
  • Match the HP rating on your existing pump label to 1.5HP to ensure hydraulic compatibility

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