Review: If you have pipe this is a coupling. - Has lots of stretch for odd sized pipes. Real thick and sturdy. The hose clamps do their job well. So easy to put on that even a house husband can install it. Decent amount of flex for misaligned pipes.
Review: Good for Lawn Vac hose Coupling needs - I needed this to couple together an existing piece of 6" vac pipe to a new piece of 6" pipe for my Agri-Fab lawn vac. This item fits the bill exactly! Was easy to instal and the clamps tightened down snugly. This is. better value than than the OEM Agri-Fab coupler and would recommend if you need to do the same. It is thick rubber and should be very durable for years to come.

### ⭐⭐⭐⭐⭐ Gives you a tight seal and a bit of flex in pipe runs
*by S***E on April 23, 2023*

Way better than using the plastic. Hopefully the rubber holds up but install was way easier and more forgiving. Plus this is $10 less than the big box store that carries it
