Use these convenient 30 PSI air nozzles to effectively clear away chips and debris. No back pressure build-up due to holes in the barrel that permit air to escape if the end is blocked. Safe-T-Blow nozzles attach directly to a plant airline without a regulator for easy installation. Non-spark materials make Safe-T-Blow nozzles safer for use around solvents and other flammables. Tamper-proof design prevents operator from increasing the air pressure. Available in straight or angled configurations.
