6 in collector inlets: cyclone flanges, inlet Ys and duct
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.
Also listed as 6 inch inlet, 6 in duct

Short answer
In our sources 6 in appears on collector inlets and cyclones, not on a hose product: Oneida's Super Dust Deputy 4/5 has a 6 in mounting flange, Oneida's 6 in models have ports sized for crimped ductwork, and the Shop Fox W1685's V2 inlet Y splits 6 in to two 4 in. The catch: the W1685's earlier V1 inlet is 5 x 4 x 4, and a 6 in port made for crimped duct is not a friction-fit hose port.

Watch out for
- Oneida sizes its 6 in Super Dust Deputy ports for crimped ductwork fittings, while its 4/5 in models use tapered ports for friction-fit flex hose. The size label alone does not tell you the joint type.
- The Shop Fox W1685 inlet is 6 x 4 x 4 only on the V2.12.01 part; the earlier V1 part is 5 x 4 x 4.

POWERTEC lists a 6 in end of 6-23/64 in OD and 6 in ID and two 4 in branches. It is a hose-fitting part; a port made for crimped metal duct is a different joint.
Questions
Can I clamp a hose onto a 6 in Super Dust Deputy?
Oneida says its 6 in Super Dust Deputy models have ports sized for crimped ductwork fittings, unlike the 4/5 in models' tapered friction-fit ports.[1]
Does the Shop Fox W1685 have a 6 in inlet?
Only on the version with the V2.12.01 inlet Y, which splits 6 in to two 4 in. Grizzly's listing also shows an earlier 5 x 4 x 4 V1 inlet.[2]
