I had some reducers custom made. These are 3"-5" I.D. 5-ply silicone reducers. Very firm and stiff which requires a good t-clamp. I have some t-clamps coming and could include one once i receive them for a additional cost. These reducers won't swell or clapse.Which is the reason I went 5-ply. Any questions feel free to ask.
