Sturgis made in USA parts for propane systems are the best way to go. Too many look alike cheap parts have been reported as a source of leaks too often.
Personally, Iíd rather not have a front row seat in the middle of a rapidly expanding propane fireball...in any case, flexible parts in propane systems need to be inspected regularly and replaced when they get hardened, exhibit cracking, or age out. I try to replace my flexible pressure hoses about every 8 years or so. I also use corrugated split tubing as a cover to protect those parts from UV light. I do the same for exposed electrical wires as well.
