Comments about Groco Groco Pipe-to-Hose 90 Degree - Full Flow - Bronze, NPT:
Just what was needed. [...] did not handle this product and while re-configuring the plumbing on the Bowman heat exchanger on my Perkins 4-108 this was the perfect solution. 1" ID hose coming out of the back of the Bowman heat exchanger flowed perfectly to this elbow without further adapters or loss of flow.
