ExtremeMist Horse Fly Spray Bottle with upgraded FKM (Viton-style) seals — engineered for improved compatibility with many oil-based fly sprays. Cheap spray bottles clog, leak, or fail when exposed to oil-based formulas, but this upgraded model is engineered to handle tougher equine fly sprays and grooming products.With just 6–12 pumps, you get a continuous, ultra-fine mist or a focused jet stream — covering large areas quickly with less hand fatigue. ⚠️ IMPORTANT COMPATIBILITY NOTICE This sprayer is equipped with FKM (Viton-style) seals, which offer improved resistance to many oil-based fly sprays and additives. However, compatibility is not guaranteed for every brand or formulation.Highly solvent-based or petroleum-heavy mixtures may still degrade seals or internal components.
