This is a genuine Fluidra replacement union nut sized for 110 mm connections on the Cepex CPVC spring check valve range covering pipe diameters D90 to D110. The union nut secures the valve’s end connector to the pipeline, enabling the true-union design that allows the valve body to be removed and serviced without disturbing the surrounding pipework. It is an essential spare part for maintaining leak-free, reliable non-return valve installations in pool, irrigation, and industrial fluid systems.<\/p>\n
This union nut is designed exclusively for Fluidra’s Cepex CPVC spring check valves in the D90\u2013110 diameter range. It is not interchangeable with PVC-U valve variants or with valves outside the D90\u2013110 size family. Always verify your existing valve’s model and pipe diameter before ordering to ensure a correct fit.<\/p>\n
As a genuine Fluidra part, this union nut is manufactured to the exact thread profile and dimensional tolerances of the original valve assembly, ensuring a secure, pressure-rated seal every time. CPVC (Corzan\u00ae-grade) construction provides excellent chemical resistance and dimensional stability, making it well suited for pool water, treated fluids, and demanding industrial environments. Third-party alternatives risk mismatched threads, premature wear, and potential leaks.<\/p>\n
The union nut threads onto the valve end connector and should be hand-tightened before being brought to final torque. No solvent cementing is required for the nut itself. It is advisable to inspect the mating O-ring or gasket at the same time and replace it if worn, to guarantee a leak-free joint after reassembly.<\/p>","protected":false},"excerpt":{"rendered":"
