It always seems to be the two pipes you want to join are the same size. This coupler works.

Fitting to fitting
Sometimes you need to connect one fitting directly to another fitting. This is the best and most direct way to do it.

fit is very good
I I used these to connect a Y to one output of my dust collector and routed it to my mitre saw through blast gates. Now I don't have to disconnect my table saw hose when I use the mitre saw. The fit is just right. I will be ordering more as spares.

Dust coupling to connect the 45 bend to the plastic splitter
nice snug fit between the 45 bend and the splitter as you'd hope. Haven't connected the full system yet but i don't expect any issues.

I finally found one.!
Perfectly works for my Portable Bosch 1231 table saw and my dewalt miter saw. using my rigid 16 gallon wet and dry. Looked all over home centers and couldn't find one . Went to Rockler and it was just staring at me. Excellent quality whoever invented this.

no other recourse, though they have gone up from the $2.99 price to $5.99 of just a couple years ago. Quite ridiculous.

Primarily because you did not size your clear plastic tubing to accept your fittings. Increases the profit for you but adds extra expense (esp. at $3.99 a pop for the couplers) for the customer. Most of these will be part of the 2.5" portion of the system collecting dust from my drill press, router, joiner and table saw.

BEST ANSWER: Not at this time.
tech drawing shows ID of 2 1/2 and OD of 2 1/2 ... ... does not seem possible. Are the two ends different? if so then tech drawing should have ID and OD for both ends.
Kamalapati on Dec 31, 2017
BEST ANSWER: Both is a are for the 2 1/2 inch hose or the clear tubing
Is the coupling (2 1/2" or 4") tapered on the inside?
Duci98 on Dec 8, 2015
BEST ANSWER: not so much tapered but the fit is snug. When dealing with couplings the measurement will always fit the size hose you are trying to couple.... If its too small just add some tape or weather stripping, too large and you could grind or sand out to fit. Also a heat gun always comes in handy when trying to get good fits.
Can you attach a T connector directly to the stable gate with a coupler?
