Tips for Connecting Two Hoses
| Connecting Festool hoses. |
All Festool Dust extractors have vacuum inlets that accept any 50mm or 2 inch standard hose ends. The 2 inch standard hose measures 2 inches, or 50mm on the INSIDE dimension. The outside diameter of a standard 2" hose end coupler is actually 2 1/4", and the inlet in the Festool dust extractor has a 2-1/4" opening. This is the standard in the industry for most shop vacs. Any 2" standard hose will fit the Festool machines.
The 50mm Festool hose has a 2-1/4" inch coupler on each end. All that is needed to join another hose with a standard fitting is an open tube with an internal opening of 2-1/4" diameter. The Festool item #493047 connector sleeve can couple to either end of this hose and accept the 2-1/4" standard end of any 50mm, 36mm or 27mm Festool hose.
The 36mm Festool hose has a tool tip of flexible rubber mounted to a hard plastic rotating shell. This can be removed and replaced with a #452894 or #452893 rotating adapter, which is the standard 2 inch coupler with the 2-1/4" inch outside diameter. This is the same as what comes on the other end of the 36mm hose. Then, all that is needed to couple any other standard hose is again, the open tube #493047 connector sleeve. This piece is conductive to static and will properly complete the circuit to ground if both hoses are of the green and black AS variety.
Alternate 36mm method
There is an alternate and much quicker method to convert the tool end of the 36mm hose to a 2-1/4' opening. The #452897 Suction adapter is the funnel shaped open tube, the small end of which can be inserted directly into the tool tip of the D36 hose and will provide a 2-1/4" opening for any other hose. However, this piece is not made of conductive material, and for antistatic use, a piece of foil or conductive wire could be used to bridge across the junction.
The 27mm Festool hose is 12 feet long and another 12 foot D27 hose coupled to that is very inefficient because of the extreme restriction of air flow. It is best to couple the 27mm hose to the end of a larger diameter 36mm or 50mm hose to provide better air flow. But if needed, the rubber tool end could be removed and replaced with the #452892 rotating adapter and the two hoses joined with the open tube #493047 connector sleeve.
The rotating adapters and the tool tips are both removed and installed as assemblies of three parts. A removable clip ring secures the inner sleeve, which is the only part that is actually attached to the threads of the hose. The clip ring is secured to the outer shell with two tabs that engage into slots in the shell. To remove, push in the tabs with a flat blade screwdriver.
