Airstream Blowstick Replacement Valve This is the replacement valve for the Airstream Blowstick and for the RG Hardie Flexi-Stick Tip: You'll need to unscrew the blowpipe to replace the valve, but it can be tight. We recommend wearing rubber gloves, to get a good grip on both pieces. It's a safe and effective way to separate the pieces, without tools that could damage the blowpipe.
