 Very poor product! March 24, 2008
This is the first and last Jet product I'll ever buy. Very poor design includes a internal mitered corner that has sharp edges and reduces flow area by at least a third. If you want a dust collector that plugs up use these elbows.
 It does what I wanted it to... July 12, 2006

I read evrywhere to avoid 90 degree bends in my ducting if possible - and I did - but there was one place in my shop where it was unavoidable. I used this elbow to solve the problem and I have not noticed a significant difference in the airflow or dust collector performance. By the way I have a one car garage shop with a Jet DC650 collector.
Bottom line, don't make sharp bends in your ducting if you can avoid it. If you must bend, use these but use them sparingly and you should be fine.

I AM A HEAD PORTER SO I KNOW AIRFLOW.YOU WILL GET BETTER AIR FLOW JUST BENDING YOU HOSE.WHEN THEY SAY IT IMPROVES AIRFLOW THEY ARE WRONG AND HAVE KNOW IDEA WHAT THEY ARE TALKING ABOUT AND I WONDER IF THEY OWN PART OF THE COMPANY .THE INNER DIAMETER IS REDUCED TO 3 INCHES OR LESS BY A VERY SHARP CORNER SLOWING DOWN AND REDUCING AIRFLOW ALOT. IF YOU DO BUY THIS POORLY DESIGNED ELBOW. TAKE A FILE OR DREMMEL TOOL TO SMOOTH OUT THE RIDGE. THAT WILL INCREASE AIRFLOW ALOT.ESPECIALY IF YOU HAVE A WEEK DUST COLLECTOR YOU NEED TO.IT WILL ADD ABOUT 300CFM OR MORE AIRFLOW. THATS LIKE CAMPARING A 700CFM CARB. TO A 1000CARB.ITS A BIG DIFFERANCE.IF YOU DONT HAVE TO BEND YOUR HOSE AS MUCH AS THE ELBOW DONT USE IT. AIRFLOW IS MORE VALUBLE THEN LOOKS.ANYONE SAYING THERE ARE NO RIDGES IN THIS ELBOW WELL THATS A PLAN OUT (LIE)AND REDICULOUS. THIS WAS A HONEST REVIEW. GOOD LUCK

When installing a dust collection system, eliminating resistance to airflow is what it is all about. The ideal is as large a pipe as possible, flowing in a straight line, without any ridges in the surface. Of course in the real world at least some of these things wind up being less than ideal. What this Jet 4" elbow does, is give you a large pipe, that makes a gradual turn as opposed to a straight 90 degree angle, and the sides of the elbow are smooth. So when you need to make a turn with your air flow, this elbow does the nicest job.
The fit snugs neatly inside the standard 4" flex pipe. With some 4" Jet wire clamps which are also highly recommended over standard pipe-band clamps and this Jet elbow your all set for some hassle free collecting.
Good enough! January 29, 2002

I attached this elbow directly to the intake port of my Jet dust collector. If you don't suspend your 4" hose from above, then using this elbow allows you to run the flex hose horizontally to a piece of equipment (also saving hose length). May not be completely necessary, but it does take the stress off the hose, especially if you move it around a lot.
