Trevi A963427NU Thermostatic Temperature Cartridge Adjustment Carrier and Handle Extension (Ideal Standard)

Summary

A963427NU Ideal Standard / Trevi Thermostatic Temperature Cartridge Adjustment Carrier and Handle Extension

Trevi A963427NU Temperature Adjustment Carrier and Handle Extension

The Trevi A963427NU part is a temperature adjustment carrier and handle extension for select Trevi and Ideal Standard shower and mixer valves. It allows correct handle and cartridge alignment when replacing internal temperature-regulating components.

Function

This carrier and extension connects to the internal thermostatic cartridge and ensures the handle turns smoothly and adjusts temperature correctly, maintaining safe water mixing control after maintenance or replacement of internal parts.

Confirmed Compatible Valve Models and Mixer Ranges

• Trevi Link exposed thermostatic bath-shower and shower mixer valves used on high-pressure balanced systems
• Trevi Flight exposed thermostatic bath-shower and shower valves for balanced systems
• Trevi Attitude recessed or exposed mixer valves where manufacturer spare-parts listings include A963427NU as the temperature adjuster extension
• Trevi Melange shower valves and mixers marked compatible in spare-parts listings with A963427NU temperature adjustment carrier
• Ideal Standard and Trevi branded exposed or concealed thermostatic valves and mixers listed under spare-parts catalogues using A963427NU for temperature control mechanisms

Other Trevi or Ideal Standard mixer and shower valves may also be compatible where the spare-parts documentation explicitly specifies A963427NU as the temperature adjustment carrier or handle extension. Always verify against the valve’s parts listing or check the code stamped on the existing carrier before ordering.

Selection and Verification

Before ordering, ensure your valve is listed in the official Trevi/Ideal Standard spare-parts diagrams as compatible with A963427NU. Carriers and extensions are not universal across different valve families, so compatibility depends on correct valve model identification, not only visual similarity.

When Replacement Is Recommended

Replace the carrier/extension when handle movement becomes stiff temperature adjustment becomes imprecise or internal thermostatic cartridges are replaced. Fitting the correct A963427NU can restore proper handle operation and reliable temperature regulation without replacing the entire valve body.
