BVV 120LB DIPTUBE Tank 70/30% N-Butane/Propane Blend - 99.5% Guaranteed High Purity USA

What the 70/30 Butane Propane Mix Actually Contains Seventy percent n-butane, thirty percent propane, guaranteed to 99.5% and sourced in the USA. The ratio is the product. Propane carries a much higher vapour pressure than butane. Adding thirty percent lifts the pressure of the whole mix above straight n-butane, while butane stays the volume component. Choosing an N-Butane Propane Blend Over Straight Butane Pressure is the practical difference and it cuts both ways. A blend at this ratio moves more readily at a given temperature than pure n-butane, which is useful when ambient conditions are working against you. It also means the vessel and every fitting downstream see higher pressure. An n-butane propane blend is not a drop-in swap for a pure butane system without checking equipment ratings first. Purity is guaranteed at 99.5%, and the material arrives clean, colorless and odorless. There is no mercaptan in it. Consumer fuel gas carries that additive so a leak is obvious to anyone nearby, and its absence here shifts that job onto detection equipment. The tank is DOT refillable LP with a dip tube, drawing liquid rather than vapour. BVV recommends distilling any solvent before use, which is worth doing regardless of what the certificate says. Key Features 70% n-butane, 30% propane: A supplier-blended ratio, guaranteed to 99.5% and sourced in the USA. Higher vapour pressure than pure butane: The propane fraction lifts working pressure, which helps in cool ambient conditions. Dip tube for liquid withdrawal: Draws liquid from the bottom of the tank rather than vapour off the top. No mercaptan odorant: Clean, colorless and odorless, so leak detection cannot rely on smell. 120 lb DOT refillable LP tank: Bulk format. Confirm downstream equipment is rated for the higher pressure. Technical Specifications Specification Value Blend 70% n-butane / 30% propane Guaranteed Purity 99.5% Tank Class 120 lb Tank Type DOT refillable LP Withdrawal Dip tube, liquid Odorant None, no ethyl mercaptan Appearance Clean, colorless, odorless Origin USA sourced Handling and Regulatory Notes Use only in a well-ventilated area, and only for purposes permitted under your local laws and ordinances. BVV advises distillation of every solvent before use. California restricts retail supply of butane above 150 mL. Permitted channels are listed under CA Bus & Prof Code Division 10 and CA Health & Safety Code 11362.775.
