Siamp Optima 50 Dual Flush Mechanism, White Ceramic Plastic

The Siamp Optima 50 dual flush mechanism includes a 470mm cable, 2″ bayonet fitting, and an Optima 50 push button. This product can be installed in both ceramic and plastic cisterns, serving as a replacement for pre-installed products from brands such as Vitra, Twyford, Lecico, and Roca. The mechanism allows for straightforward maintenance, as the universal bayonet permits removal with a simple anti-clockwise 1/4 turn, eliminating the need to disconnect the cistern from the WC pan. With adjustable height between 272mm and 480mm, and an overflow that can be modified from 149mm to 245mm by cutting in 4mm increments, this flush mechanism offers excellent adaptability. The push button is compatible with lid hole diameters ranging from 38mm to 44mm. The product is WRAS approved and comes with a 10-year guarantee for peace of mind.
