The cartridge corresponds to the defective 46 mm cartridge in my Grohe shower fitting to the plastic ring for fixing the chromed trim. Unfortunately, plastic ring and trim did not fit together, so that the old, no longer quite intact rubber ring had to be used. Otherwise, the cartridge is functioning properly and finally now allows a smooth change in both the mixing ratio hot / cold water and the discharge quantity. Positive can be further noted that the cartridge is supplied complete with all mounting hardware.
