We had a request from a customer to bend 3 inch PVC in a 21” diameter arc. For a demonstration prototype they were building for a navy customer. After reviewing their design sketch we suggested using two ½ inch Bendits with a 1 ½ inch sleeve to increase heating diameter. We also suggested that they could get a tighter bend with a little smaller diameter pipe and still prvide a curved conduit that would meet their needs. The photos are of the finished bends. The Aerospace customer said:

“Just wanted to say thanks for getting me the equipment so quickly. I have attached a picture of successfully bending a 2.5” White schedule 40 PVC as well as 2.5” Harvel clear schedule 40 PVC pipe into a 9.25” radius. Everything worked out fantastic and we’ll be testing things next week.“
