Watch out for

  • Your inlet depends on your machine's version: the V2.12.01 inlet Y is 6 x 4 x 4, the earlier V1 inlet is 5 x 4 x 4. Order by version, not by model number alone.
  • Grizzly's version codes read as version and first-use date (V2.01.17 is version 2, January 2017), which is how to match a part to your machine.
  • A 6 in or 5 in opening is not a 4 in hose size; a reducer or wye has to match the opening your version has.
