Why this wet end stands out among spa components is in the details Gecko designs around. The FMXP2 is purpose-built for 56-frame systems, delivering a compact yet robust solution that slides into existing spa pump setups without drama. Its 2" MBT connections and 6.3" diameter give you a precise, tight fit that minimizes leak points while maintaining solid flow characteristics. And because Gecko positions itself as a spa-focused partner, you’re not just buying a component—you’re investing in a part designed to interact seamlessly with spa controls, user expectations, and long-term durability.

Important compatibility note: 56-frame spa wet ends can be designated as either 6.1 or 6.3. The key difference is the distance between the top two thru-bolts: 6.1 is measured at 4", while 6.3 measures 4-1/8". The FMXP2 falls under the 6.3 classification, matching spas and volutes that require that slightly larger thru-bolt spacing. Verifying this detail ensures a clean, secure installation and reliable sealing over time.

Gecko positions AquaFlo as a practical, affordable alternative to other major brands like Balboa Water Group, while still delivering the high level of reliability spa owners expect. The FMXP2 embodies that balance: solid performance without overcomplication, backed by Gecko’s commitment to meaningful, user-friendly design. If you’re retrofitting a spa or building a new one that uses a Flo-Master XP2 wet end, this 1.5 HP unit provides the right mix of power and compatibility to keep jets, heaters, and controls responsive and consistent.

This wet end is ideal for:

• Spas currently using a Flo-Master XP2 configuration in 56-frame systems seeking a direct replacement or upgrade
• Installations with 2" MBT suction and discharge piping looking for a compact, reliable 1.5 HP solution
• Retrofits where the control system expects Gecko Alliance components and straightforward maintenance
• Budget-conscious projects that still require dependable spa pump performance and long service life

Practical advantages you’ll notice in daily use include steady flow with minimal vibration, straightforward maintenance access due to the 8-screw fastening, and a design that aligns with Gecko’s philosophy of intuitive interaction. No extra suction or discharge ports mean fewer potential leak points and fewer parts to source during service, helping you keep downtime to a minimum. When you want a trustworthy wet end that slots into your 56-frame spa without fuss, the FMXP2 delivers the right combination of power, compatibility, and peace of mind.

Whether you’re upgrading an aging system, replacing a failed unit, or specifying components for a new spa build, choose the Gecko AquaFlo FMXP2 1.5 HP Flo-Master Wet End for a reliable, spa-focused solution that’s engineered to perform and built to last.
