Review on 🚀 JACO Lightning L2-Series Tire Air Chuck - 1/4" Female NPT , Open Flow (2 Pack) – Enhanced for SEO by Sean Copeland

Very good replacement 90 degree chucks that lock and unlock the valve stem with little to no air loss unlike others that are difficult to remove and cause a second psst. They lock at 90 degrees. ° Angle without rotation. The locking knob rotates to best fit your finger. I recommend attaching to a 1/4 fitting that swivels so you don't have to struggle with twisted hoses. This is an open flow cartridge which allows air to flow freely out of the hose - you need an inflation valve to keep the air and compressor in line.
