The VapCap O-ring kit is a five-piece replacement seal set that restores an airtight fit to your DynaVap tip, mouthpiece and condenser after months of heat cycles. If your VapCap has started wobbling, whistling, or drawing loose, these are the rings you need to buy and swap in before your next session.
Why your VapCap needs fresh O-rings
Worn seals are the number-one reason a VapCap loses its click-and-draw feel, and the VapCap O-ring kit solves it in under two minutes. DynaVap tips run hot — you're heating stainless steel or titanium with a torch until the cap clicks at roughly 180–210°C, which means the rubber seals take a beating every single session. After 300–500 clicks, the rings harden, shrink by up to 15%, or start leaving black marks on your condenser. You'll notice it as a loose tip, a mouthpiece that falls off in your pocket, or an airy draw that won't pull vapour properly.
The metalwork lasts essentially forever; the rubber doesn't. Five fresh rings for under 3 euros restore the snug, confident fit the device had out of the box — and given that a full VapCap costs around 80 euros, a 3-euro ring swap is the single best-value fix in the whole DynaVap ecosystem.
What fits what — the DynaVap O-ring map
One kit covers the whole device, front to back, with all five rings matching OEM spec. These are identical to the factory rings DynaVap ships on their current line.
| Part | O-rings used | Purpose |
|---|---|---|
| Titanium tip (Ti) | 2 rings | Seal tip to condenser |
| Stainless steel tip (M tip) | 2 rings | Seal tip to condenser |
| Mouthpiece assembly | 1–2 rings | Hold mouthpiece to stem |
| OmniVap condenser | 2 rings | Adjustable airport seal |
How to replace your VapCap O-rings
Replacement takes under 2 minutes per ring and needs only a toothpick and a cotton bud. Follow the five steps below in order.
- Disassemble the VapCap completely — cap off, tip unscrewed from condenser, mouthpiece pulled from stem.
- Use a toothpick or dab tool to roll the old rings off the grooves. Don't use metal — you'll scratch the titanium.
- Wipe the grooves clean with an isopropyl-soaked cotton bud. Residue builds up under the rings and stops the new ones seating properly.
- Stretch each new ring over the tip and roll it into its groove. Work it round evenly so it doesn't twist.
- Reassemble and do a dry pull. You should feel resistance — that's the seal doing its job. If it still draws loose, double-check the ring is fully seated.
From our counter: when to swap them
Daily users should order a fresh kit every 3–4 months; weekend users get about 12 months per set. We get VapCap owners in the Azarius shop asking why their device suddenly tastes off or clicks weakly. Nine times out of ten it's the O-rings. Keep a spare kit in your stash tin — you'll need them eventually, and nobody wants to wait on a delivery when the rings on your only tip have just given up mid-session.
One honest limitation: these are high-temp rings, not indestructible ones. If you consistently over-torch the tip (waiting more than 2–3 seconds past the click), you'll cook any rubber eventually. The fix is better technique, not a different ring.
How the VapCap compares to other dry-herb vapes
Unlike battery-powered vapes where a dead cell means a dead device, a VapCap with worn rings is fixable in under 2 minutes for the price of a coffee. Compared to a Mighty or Crafty+ (which need factory servicing for seal issues at around 40–60 euros), the DynaVap's all-metal, torch-powered design means ring replacement is the only routine maintenance — no firmware, no battery degradation, no warranty returns. That's why the VapCap O-ring kit is the single most-bought accessory in our DynaVap lineup.
Pairs well with the DynaVap cleaning kit for a full service, and a proper torch lighter if you're still using a wobbly jet flame. Complete your setup with a VapCap carrying tube so the tip doesn't rattle loose in transit.

Frequently Asked Questions
How often should I replace VapCap O-rings?
Daily users: every 3–4 months. Occasional users: once a year. Replace sooner if you notice a loose tip, airy draw, or black marks on the condenser — those are classic worn-ring symptoms.
Are these the same rings DynaVap ships from the factory?
Yes — the kit matches the OEM spec used on current M tips, titanium tips, mouthpiece assemblies and the OmniVap condenser. No shimming or trimming needed.
Can I use standard O-rings from a hardware shop instead?
Standard nitrile rings melt or harden quickly at VapCap temperatures. These are high-temp silicone rated for the heat your torch puts into the tip, which is why DynaVap uses this exact spec.
Will one kit do the whole device?
Yes. Five rings covers the tip (2), mouthpiece (1–2) and condenser (2) with enough for the full rebuild or a couple of partial swaps. Keep leftovers in a small tin — they don't expire on the shelf.
Do the rings affect flavour?
Fresh rings taste neutral. Very worn rings can transfer a faint rubbery note or rattle bits of degraded silicone into the airpath, which is another good reason to swap them on schedule.
How do I get the old rings off without scratching the tip?
Use a wooden toothpick or plastic dab tool to roll them off. Avoid metal picks on titanium — even a small scratch can trap residue and make future cleaning harder.
Where can I buy the VapCap O-ring kit in the Netherlands?
You can order it directly from Azarius in Amsterdam — our stock matches the OEM DynaVap spec, and local shipping maps onto the standard Dutch next-day delivery window.
