Sapphire silt jets are high performance desilter nozzles for use in cable ducts and drainage systems. Their short body makes them ideal for smaller diameter ducts and for negotiating ducts with pre-existing cables in situ. They have top quality threaded inserts rather than the drilled holes found in less expensive nozzles and are suitable for use on all Flowplant trailer and van mounted desilters and jetters.

Available with 3 or 6 rear facing jets and a front jet option they provide excellent cleaning performance and unblocking ability in pipes and ducts from 75mm (3″) diameter.

The inserts can be unscrewed and cleaned if they become blocked with grit or need replacing.

Note: When used for cable duct desilting the nozzle will be jetted for 140 bar maximum pressure.
