High-Speed Cyclone Shop Vac Swap Kit
$20
If you have more than one shop vacuum and want to quickly jump from vac to vac but maintain the rigid connection, create a second setup. You'll cut this pipe to the inlet height of your second vac (with included PVC Cut Assist Sticker as an aide), friction fit to the Blind Tee and have it handy for a jump over to your second shop vacuum.
