Cap Armor — Stainless Steel Sleeve Upgrade for DynaVap Captive Caps
More mass. More heat retention. More power — without replacing the cap you already love.
Cap Armor is a precision-machined stainless steel sleeve designed to snap over a compatible DynaVap Captive Cap, adding serious thermal mass and heat retention to your setup. Think of it as a modular alternative to an Armored Cap: you keep using the cap you already trust, but you gain a smoother, more consistent heat cycle and a noticeable bump in extraction performance.
The big quality-of-life upgrade is heating. With added mass surrounding the cap, heat spreads more evenly through the sleeve, so you can aim your torch and heat without constantly spinning your device. That means less technique, fewer hot-spots, and an easier path to repeatable results — especially for anyone chasing that “one-hit” style extraction. In real-world use, Cap Armor can help push your DynaVap toward full extractions in 1–2 heat cycles with less guesswork.
Because it’s modular, Cap Armor can be installed or removed whenever you want. It’s not difficult to take on and off, but if you plan on using it daily, many users prefer dedicating one to each cap in their rotation. It’s affordable, it’ll last forever, and it’s one of those upgrades that simply makes the whole DynaVap experience easier and more effective.
Features
- Modular performance upgrade: Precision-machined stainless steel sleeve that clicks onto compatible Captive Caps to add mass instantly.
- Enhanced heat retention: Added thermal mass smooths heating, extends cycles, and improves thermal consistency.
- No-spin heating: More even heat spread means you can aim the torch and heat without constant rotation.
- Stronger extractions: Helps support full extraction in 1–2 heat cycles.
- Microdose friendly: Still works with the DynaVap half-bowl setting for efficient small loads.
- Built to last: Stainless steel construction designed for years of daily use.
Compatibility
- Compatible with: Captive Caps in good condition
- Not recommended for use with: Non-Captive Caps, dented caps, PVD-coated caps, or Special Edition engraved caps
How to Use
Install: With your Captive Cap on an assembled device, gently press the cap into Cap Armor until you hear an audible click.
Remove: While the cap is installed on a tip, brace your thumb on the digger-outer against the tip, then gently wiggle and pull Cap Armor off. Do not push from the top to separate — this may dent the cap.
Notes
Because this is a press-fit design, minor dents or impressions on the upper crimp of the Captive Cap are possible. This is normal and will not affect function of either part.
