ASP Palm Defender D1 Insert, Heat OC or Inert Pepper Spray

Overview of the ASP Palm Defender D1 Insert | 54910

Ready Protection, Reloadable Design

When you carry a defensive spray, the last thing you want is a throwaway can that fails when you need it. The ASP Palm Defender D1 Insert solves that problem. Instead of a disposable aerosol, this is a precision-machined, replaceable cartridge that drops into your ASP Defender, so your device stays with you for years while only the insert (MPN 54910) gets swapped out.

Each insert is built from aerospace aluminum and solid brass, with a specially produced valve, a patented dispensing mechanism, and a fully O-ring sealed body. You can see the quality in the details: a color-coded cap, a gold collar, and the ASP eagle medallion on every unit.

Choose the Heat (OC) formula for maximum-strength, law enforcement-grade protection, or the blue-capped Test (Inert) cartridge for safe, realistic practice. Law enforcement officers, security professionals, and everyday self-defenders rely on this system to stay ready and to train the way they carry.

Key Features

• Replaceable Insert Design: Reloads your ASP Defender instead of forcing you to buy a whole new device, keeping MPN 54910 (Heat) and 54911 (Inert) affordable to restock.
• Aerospace Materials: Precision-machined from aerospace aluminum and solid brass for durability and reliable dispensing.
• O-Ring Sealed: The entire unit is O-ring sealed to protect the contents and support consistent performance.
• Heat (OC) Formula: Maximum-strength, law enforcement-grade oleoresin capsicum at 10% OC, 1.4% major capsaicinoids, and two million Scoville Heat Units.
• Invisible UV Dye: Heat inserts include an invisible UV dye to assist officers with assailant identification after deployment.
• Inert Training Option: The Test (Inert) cartridge sprays a harmless, inert aerosol so you can practice deployment before carrying live OC.
• Consistent Output: Each insert delivers approximately six 1/2-second bursts with an effective range of about five feet.
• Color-Coded Identification: Red cap for Heat OC, blue cap for Inert training, both topped with a gold collar and the ASP medallion.
• Date-Coded Reliability: Heat inserts are date-coded; dispose of them after the marked date per your local environmental regulations.

Variant SKUs, MPNs, and UPCs

Compatibility

The D1 Insert is designed for the ASP Metro D1 Defender and the Sport D1 Defender. It is a direct-fit replaceable cartridge for those D1 units, so you can reload rather than replace your device.

This insert is specific to the D1 platform. It is not intended for non-D1 ASP Defenders or for other brands of defensive spray. If you are unsure which Defender you own, check the model marking before ordering.

Note the legal limitation: pepper spray cannot ship to AK, DC, HI, MA, NY, Puerto Rico, or the Virgin Islands, and OC inserts ship by ground service only. Inert Test inserts contain no OC.

Intended Users

Law enforcement officers choose the Heat (OC) insert because it delivers a maximum-strength, agency-grade formula with UV dye that supports assailant identification. Security guards and loss-prevention professionals keep a reloadable defensive option ready without discarding the whole device each time.

Everyday self-defenders, commuters, students, and preppers carry the Palm Defender for compact, reliable protection they can refresh on their own schedule. Firearms and defensive-tactics instructors rely on the Test (Inert) cartridge to run realistic, repeatable training reps before anyone handles live OC.

What's Included

• One ASP Palm Defender D1 Insert in your selected formula (Heat OC, MPN 54910, or Test Inert, MPN 54911).
• Twin Pack options (54912 Heat, 54913 Inert) include two matching inserts.
• The combination pack (54914) includes one Heat (OC) insert and one Test (Inert) insert.

The ASP Defender device itself is sold separately and is required to use this insert. A Test (Inert) cartridge is strongly recommended alongside any Heat purchase for safe practice. https://wcuniforms.com/products/asp-palm-compact-defender
