Question by: Dale W on Jan 25, 2026, 11:58 AM

Does this hose actually hold up to both butane and propane, or is it really just meant for one of 'em?

Answer by: Customer Support on Jan 27, 2026, 6:38 AM

Built to handle both fuels on the same line, which is part of what makes it useful when you're running equipment that doesn't always use the same fuel source. The synthetic rubber tube and stainless steel wire reinforcement are what carry the load there, and the polyester impregnated cover gives it solid abrasion resistance on top of that. One hose covering multiple fuel options means less inventory to keep track of and fewer compatibility headaches.

Will this hose hold up to being bent some? Need to snake it around a piece of equipment.

Answer by: Customer Support on May 17, 2025, 10:52 AM

It can handle a bend radius down to 1.5 inches without kinking or damage. Just keep that in mind when routing it.

got a tight spot to route fuel hose, how sharp can this -4 line bend without kinkin it

Answer by: Customer Support on Feb 19, 2026, 6:45 AM

For routing, the minimum bend radius is 1.5 inches. Keeping bends at or above that radius helps it hold shape without kinking.
