I have 2 D27 DM-AS/CT vacuum hose end adapters. They upgrade the older 27 mm hoses to the new bayonet style hose connector for the newer tools. They will also work with the older style tool connectors as well. I have used these to adapt non Festool hoses to work with my Festool tools. I am asking $20 each or $35 for both. Shipping included and no sales tax charged. I only accept PayPal payment.
