A nozzle washer must be used to prevent premature wear and failure of both the holder and nozzle from abrasive. The blast hose operator inserts a nozzle washer into the nozzle holder and screws in the nozzle, turning it by hand, until the nozzle sits firmly against the washer.
When choosing a pack of washers, ensure that the size corresponds to that of your blast nozzle and nozzle holder for the right fit and a tight seal. For reference: 21580 fits CT nozzle; 91024 fits TMP nozzle, 91026 fits TXP nozzle; 00869 fits TSP nozzle model.
Always replace parts with authentic Clemco products for guaranteed compatibility.
