About this wet end

This Aqua-Flo by Gecko 48Y frame wet end (part #91041820-000) is designed for 2.0HP spa pumps using 2" MBT (male buttress thread) connections. The 48Y frame size makes this wet end compatible with various spa and hot tub systems that originally came equipped with Aqua-Flo FMXP2e pumps.

Built to OEM specifications, this wet end delivers the exact fit you need to restore your spa's circulation system. We guarantee compatibility and back every part with our 1-year warranty, plus most orders ship the same day for minimal downtime. When installing, ensure your pump motor matches the 48Y frame specification and verify the 2" MBT threading aligns properly with your existing plumbing connections for a secure, leak-free seal.
