Well made. I purchased 1 model. It has a very slight taper which makes getting the hose on easy and the hose is not a super tight fit. The material is thick enough that it will not deform easily.

I have made purchases from Aircraft Spruce with total satisfaction.  Items are accurately described, prices very fair, service outstanding.
A refreshing approach to internet sales in this age of ever-increasing misrepresentation and over-pricing of inferior merchandise by many internet sellers.
I am thankful for finding Aircraft Spruce, and appreciate their solid service as well as their pricing policies. They are a business model for others to emulate.

Stamped aluminum component, thin material and therefore lightweight, exactly like the images.  I am attached a rubber hose to the end and my only issue is there is no flare to help seal the hose and keep it from coming off after clamped onto the duct.  But this is purely related to my use, and I suspect I will not have any issue otherwise (I dont think this was designed to have a rubber hose clamped to it).

 Product looks very good, just as all the other flanges I have purchased from AS over the years.  
The only downside is that I had to modify my oil cooler plenum box due to AS not having a 4 flange.

  I have always had very good experiences obtaining parts from Aircraft Spruce. I had been trying to find a 2 inch flange for some time, and was surprised when it was available. Although this time it took several weeks to get the flange due to your suppliers delivery time. You delivered the flange promptly when it was available to you. The next time I need something special I will call Aircraft Spruce first.
Thank you,

 This product is ok although the recent price increase is making me rethink the future of this piece in my automotive products. I also notice the quality of aluminum this flange is made of has changed to a lower grade. The previous version polished up very nice which gave my product a beautiful finish. Unfortunately I cannot polish the lower grade so now I’m considering having these fabricated somewhere else.
