JD Squared Model 32 Manual Tube Bender Price includes Manual Bender inc telescopic handle and degree ring. The Model 32 is essentially, a heavy-duty version of the Model 3 bender (made for over 35 years in the USA) but with a few extra features built in. Many customers, bending larger sizes or wanting portability, may want to upgrade the manual machine to hydraulic assistance. Whilst this is possible on the original JD2 Model 3 bender, the Model 32 frame is designed and manufactured with separate pivot mounting holes allowing a trunnion mount turning on its centre axis, rather than the Model 3's side mounted block coming off of one of the frame mounting bolts. This trunnion design greatly reduces the possibility of seal wear from side loading on the hydraulic cylinder. Another feature.
