3 in to 4 in duct adapter for fart fan
Solid quality what I wanted to transition 3 in to 4 in duct on my fart fan and thicker gauge should hold up to venting after taco Tuesdays. Last piece couldn't handle noxious gases.

Just what I needed.
Very sturdy and reliable. Used Foil tape to wrap around the joints inside and outside as a precaution and has worked great since.

Does the job
Needed to reduce a larger pipe section down and this did the job.

Extremely good quality
This is a very sturdy adapter that will take all the clamping you can put to it. It's made for clamping more flexible hoses and pipes OVER it. If you need to jury-rig a pipe inside the openings, look for a more flimsy fitting--you will not be able to compress this over something else with a standard clamp.
