ASP Defender Heat OC Insert D1 – Replacement Pepper Spray Cartridge
The ASP Defender Heat OC Insert D1 is a professional-grade replacement cartridge designed for ASP Metro D1 and Sport D1 Defender systems. Unlike disposable aerosol defense sprays, ASP Defender Inserts are highly engineered personal protection components built for dependable performance, precision deployment, and long-term reliability.
Manufactured from aerospace-grade aluminum and solid brass, these OC inserts feature a specially engineered valve system and patented dispensing mechanism for controlled and consistent spray delivery. The entire unit is O-ring sealed to help maintain integrity and reliability during everyday carry and defensive use.
Loaded with ASP’s powerful “Heat” formulation, this insert contains law enforcement-grade 10% Oleoresin Capsicum (OC), 1.4% major capsaicinoids, and an impressive two million Scoville Heat Units (SHU) for maximum stopping effectiveness. The formula is designed to create intense eye, skin, and respiratory irritation to help deter aggressive threats and provide valuable time to escape dangerous situations.
New for 2024, ASP Heat Inserts now include invisible UV dye to assist law enforcement in suspect identification after deployment.
Compatible with ASP Metro D1 Defenders and Sport D1 Defenders, each insert provides approximately six half-second bursts for dependable personal defense readiness.
ASP also offers inert Test Inserts filled with harmless aerosol for safe practice and familiarization training. Training with Test Inserts is strongly recommended before carrying an active Heat insert for defensive use.
