The Titan Professional Tools High Flow Air Blow Gun, No. 19393, is designed with 3/8" air intake thread. When used with thread sealant tape, this high-volume air gun allows for greater air flow and higher psi, with adjustable pressure between 25 to 230 psi. The gun is designed with a unique non-slip-aluminum ergonomic handle, and the tapered high-flow tip can be directed towards hard-to-reach areas. The product includes 1/4" series plug with 3/8" NPT male thread with pre-applied thread sealant, and it meets OSHA standards.
