Short answer
Grizzly lists the G8027 with a 4 in intake and, on its data sheet, a 4 in main inlet with no inlet adapter included. The catch: 4 in is a nominal label, Grizzly gives no mating inside or outside diameter, and the data sheet is deemed accurate as of October 12, 2026, so an older unit may differ. See dust-collector inlet sizes.

Watch out for
- Grizzly's data sheet is deemed accurate as of October 12, 2026 and may not describe units bought earlier, so check an older G8027 against its own manual.
- No inlet adapter comes with the G8027, per Grizzly, so any step to a smaller hose is a separate part.
- 4 in is the nominal inlet label. A 4 in hose fitting, S&D PVC and Schedule 40 PVC are different parts with different diameters.

POWERTEC sells it for 4 in dust collection systems, with a left-hand spiral. Grizzly states the G8027 inlet only as nominal 4 in, so compare the inlet with the hose before you clamp it.

POWERTEC lists a 3-1/2 to 4-3/8 in clamping range. A clamp holds a hose on the inlet; it does not make a mismatched size fit.
