With a reputation for quality, innovation, and reliable performance, you can trust Fernco as the global leader in flexible plumbing couplings.

Answer This Question

A:  The product details list fitting 1 size 2”, fitting 2 size 4”, and they are accurate. With the included tension rings, I am using this with my dust collection system. 4” on the dust collection hose and 2” on various vac hoses from 1 7/8 to 2 ½ with no issues. Hope this helps as you didn’t state your intended purpose.

        Multi use fittings
        Got this to pressure test my new sewer pipes before I bury them. Putting this fitting over the 4 inch cleanout pipe, plugging the other 2 ends with fernco caps and putting the test gauge into the 2 inch opening.

        Have about 4 of these and am using for dust collection to enable hooking up smaller ports to my 4" hose. They work great for this purpose. Haven't had a single problem yet.

        I use these in my shop for my dust collection system, going from 4 inches is common and what my dust collection system is, going down to the size of my different tools is always the challenge, and before everyone jumps on it, yes I do know there other ways of doing it, this is just my preferred method. I bought this for a project I was doing and ended up not using it, but will hang on to it, because I know there will be a use. Love these and would recommend them to any wood worker.

        It worked out well.....the small pipe that connects the grease trap and the down pipe had rusted so bad that threads where compromised, so I used a boot.
