BVV 120LB DIPTUBE Tank 50/25/25% N-Butane/Iso-Butane/Propane TRI-Blend. 99.5% Guaranteed High Purity USA

Where These Butane Tanks Sit on Size and Blend Two numbers matter before anything else. The 120 lb is the tank class, so this is bulk supply rather than a canister. The 50/25/25 is the blend: half n-butane, a quarter iso-butane, a quarter propane, guaranteed to 99.5% and sourced in the USA. This is the larger format, and it is not interchangeable with the 20 lb tank. Why a Tri-Blend Solvent Rather Than a Single Component Each component brings a different boiling point and a different polarity, and blending them widens the working range rather than committing to one. Propane runs the coldest and carries the highest vapour pressure. N-butane sits in the middle and is the volume component here. Iso-butane branches differently from n-butane and behaves differently under the same conditions. Running a tri-blend solvent means the mix is decided at the supplier rather than by you combining tanks on site. Purity is the other half of the argument. At 99.5% guaranteed, the material arrives clean, colorless and odorless, with no mercaptan odorant added. That absence matters. Consumer fuel gases carry mercaptan specifically so a leak announces itself, and without it your monitoring has to cover the gap. The vessel is DOT refillable LP with a dip tube, so it draws liquid from the bottom rather than vapour off the top. Key Features 50/25/25 n-butane, iso-butane and propane: A supplier-blended ratio rather than three tanks combined on site. 99.5% guaranteed purity: USA sourced, arriving clean, colorless and odorless. Dip tube for liquid withdrawal: Draws liquid from the bottom of the tank rather than vapour off the top. No mercaptan odorant: Nothing added to make a leak smell, so gas monitoring has to cover that. DOT refillable LP tank: The 120 lb class, which is bulk supply rather than a canister format.
