Customer Reviews for Master Flow 4 in. Round Tee

It served the purpose of connecting two expanding 4" sections to an up flow floor vent.

Easy to install and functions great if you need to modify your venting system. Do not forget to pick up some clamps to keep the Tee in place.

T Connection did not quite line up. 1-2 mm gap on one. side. metal foil tape solved issue. As expected in every other aspect.

This product is shaped like a T. It is not an S or a Y. As such, it is perfectly suitable for achieving a T intersection in your ductwork. More versatility can be achieved by using an endcap. Good luck!

This items was what I was looking for to vent the fumes from my lasers. It fit the hoses perfectly

The product worked as needed. I would recommend not pressing too hard when attaching pipe to the “tee”, as the spot welds are not very strong.

A little smaller than 4" had to go another way. The Tee was not used at all. I hope I can find something to use it on?

Good quality, perfect fit

Was actually looking to Y a vent line for dryer outlet but found the T so I am going to branch the vent that way

Same as here price was right , good quality

Ok piece of duct fit well in 4" duct

Works great! Just what I needed.

Worked great for my project and application it was needed for.
