The ASP Defender Heat OC Insert is a high-performance replacement cartridge engineered for ASP Defender personal protection systems. Unlike disposable aerosol defense sprays, ASP Defender Inserts are precision-manufactured dispersion devices built for reliability, consistency, and professional-grade defensive performance.
Constructed from aerospace-grade aluminum and solid brass components, each insert incorporates a proprietary valve system and patented dispensing mechanism designed for dependable operation in critical situations. The advanced engineering provides controlled delivery and consistent spray performance trusted by law enforcement and personal defense users.
Loaded with ASP’s maximum-strength “Heat” formulation, this insert contains 10% Oleoresin Capsicum (OC), 1.4% major capsaicinoids, and an impressive two million Scoville Heat Units (SHU) for powerful defensive stopping capability. The formula is designed to cause intense eye, skin, and respiratory irritation to help deter aggressive threats and create an opportunity to escape dangerous situations.
New for 2024, ASP Heat Inserts now include invisible UV marking dye to assist law enforcement with suspect identification after deployment.
Compatible with ASP Metro D2 Defenders and ASP Sport D2 Defenders, each insert provides approximately twelve half-second bursts for dependable defensive readiness.
ASP also offers inert Test Inserts for safe practice and training without active OC exposure, helping users build familiarity and confidence with their Defender system.
