1-1/4 in vacuum hose 1-1/4 in names the hose, not its tank end: Cen-Tec's 42324 cuff ends in a 2.25 in OD press fit. The tank and tool adapters makers name for 1-1/4 in hose.2 products that fit
1-7/8 in vacuum hose Shop-Vac's 1-7/8 in hoses and the adapter that steps to 2-1/2 in, plus why the original Dust Deputy port reads as both 2 in and 1-7/8 in.
2-1/4 in tank ends and fittings 2-1/4 in usually names a tank end's outside diameter, not a hose bore. Cen-Tec, Bosch and POWERTEC examples, and the 2-1/2 in mix-up to avoid.3 products that fit
2-1/2 in vacuum and collector hose 2-1/2 in hoses from RIDGID and CRAFTSMAN, POWERTEC's dimensioned 2-1/2 in ends, couplers and separators, and why the Dust Deputy 2.5 has no single ID.4 products that fit
4 in collector hose and fittings Four makers' 4 in parts measure differently: POWERTEC's 70136, 70291, 70147 and 70135. Collector inlets, couplings and gates, and the PVC sizes to avoid.6 products that fit
6 in collector inlets Where 6 in shows up: the Super Dust Deputy 4/5's 6 in flange, Oneida's 6 in models for crimped duct, and the Shop Fox W1685's version-dependent inlet Y.1 product that fit
Festool D 27, D 27/32 and D 36 Festool's D 27, D 27/32 and D 36 designations, the 577162 sleeve, the 452892 CT 22 and CT 33 connector and the 204920 D36 adapter, and what they do not cover.
35 and 36 mm hoses (Bosch and DEWALT) Bosch's 35 mm VAC005 hose and DEWALT's 36 mm AirLock adapter and hose are two systems, not one standard. Ends, compatible models and mm-to-inch arithmetic.1 product that fit
