Spray and jet head - has metering screw with sealing face and external thread for spray pipe union

摘要

The spray and jet head has a metering screw with an axial sealing face and an additional external thread to accommodate the screwed compression joint for the spray pipe. A socket is also provided at the end, to accommodate the thimble of the compression joint, and the spray pipe itself. To give complete separation of the chambers in the housing a sealing O-ring can be accommodated in the housing. The design gives improved sealing between the chambers, and also enables the spray pipe to be easily changed when desired.
