OLI Azor Side Inlet Float Valve 3/8" — OL0021203
The OLI Azor OL0021203 is a high-performance side inlet float valve engineered for efficiency and quiet operation. Featuring OLI's innovative delayed refilling system, this valve only begins to refill the cistern after the flush cycle is complete, saving up to 0.5 litres of water per flush.
