Imperial Mfg Group BM0037 Black Oval to Round Adapter-6" OVAL-RND CONNECTOR

This oval stove pipe was a perfect fit for my old wood stove. I was able to flex/squeeze the oval onto the stove which created a secure fit. You might want to buy and apply some stove cement if there are any gaps where the pipe meets the stove.

Worked perfect for our 1930-1940s Montgomery Wards wood oven! 7x4 oval, it comes looking a little round slight pressure in the middle when attaching made it fit like a glove! was worried it wouldn't work but it fit! Qould highly recommend, quality product.

I purchased a used antique wood stove with a non-standard oval connector. This product appeared to be of excellent quality, but it was not a good fit. The circumference measurement was right, but the oval was fatter in the center than my connector. Although I considered trying to crimp it, I ultimately decided not to risk it and returned it unused.

all seems ok

I have 3 old smaller wood stoves and each one has a different size oval flange so luckily it did fit one. The big thing is to do your measurement before buying to make sure you get the correct size. Don't see it lasting more than 1 or 2 years of burning, not the thickest of material. You get what ya pay for.
