Review on 💨 Maximize Efficiency with POWERTEC 70108 4 Inch Blast Gate for Dust Collector/Vacuum Fittings by Jerry Forehand

I bought six and for the price I would buy again but they seal very poorly and the plastic that the two shapes holding (the bits that don't move) ain't even fused together on most of the ones that came in. Even with the manifold running you can hear air whistling through these things when they're closed. Tape tape around it fits snugly (not without) If you have a spare roll of duct tape, have a little patience, don't want to spend big bucks on the best blast gates, and agree that you'll probably need to replace them in the future if they fall apart, it's worth a few Dollars they get will give you back, but don't expect quality.
