This TSP-7 Nozzle has a 7/16” nozzle orifice, 1 1/4” standard thread, and a 1” entry and durable rubber jacket. They are long-venturi nozzles that are capable of high-production blasting at a distance of 18-24 inches for hard-to-clean surfaces, and 30-36 inches for loose paint and soft surfaces. They have an expected life of approximately 300 hours.
These nozzles are lined with durable tungsten carbide and are for hoses with a 1” ID. A hose with a 1” ID requires a 1” entry nozzle paired with a nozzle holder to accommodate the 1 1/2” OD of the hose. Your purchase of this nozzle includes an NW-4 Washer.
NOTE: When your nozzle orifice goes up one size, or wears 1/16” past its original size, it’s time for a replacement.
