SAS-4 silicon carbide nozzles have a ¼” orifice size. They have brass, 1-1/4” standard thread with a 1” entry and durable rubber jacket. These long-venturi nozzles 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 500 hours.
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.
