ASP D1 Inserts for Palm, Metro or Sport Defender Pepper Spray

ASP Defenders use a proprietary, replaceable OC (Oleoresin Capsicum) Insert engineered for reliability and performance. The D1 inserts are precision‑machined from aerospace aluminum and solid brass, and incorporate a specially‑produced valve system with a patented dispensing mechanism. Each insert is O‑ring/gasket sealed and includes a precision spring valve that delivers a cone‑shaped dispersion pattern. Designed as refill replacement cartridges for ASP Palm Defender, Metro Defender and Sport Defender pepper spray, they offer durable construction and easy maintenance. Options include Heat (OC) for self‑defense and Test (inert) for safe training and practice. Keep your personal‑defense equipment stocked and ready with these precision, easy‑to‑replace aerosol inserts.
