If you’ve spent any time exploring Wuthering Waves’ open world, you’ve probably run into crafting recipes or quest requirements that call for a hard-to-find component you haven’t spotted before. For a lot of players, that component is the sealed tube, a rare resource that unlocks some of the best weapon upgrades and side quest rewards in the game. If you’re wondering how to get sealed tube Wuthering Waves, you’re in the right place. I’ve farmed over 30 of these across three playthroughs, and I’m breaking down every reliable method, plus common mistakes to avoid so you don’t waste hours chasing dead ends.
Core Methods to Get Sealed Tube Wuthering Waves
Sealed tubes don’t drop from common enemies, so you won’t get them just by grinding random mobs around the map. All reliable sources are tied to specific activities, and I’ve sorted them by how much time they take per drop, so you can pick the method that fits your playstyle. Drop rates for sealed tubes hover around 15% for most activities, so you’ll want to stack as many chances as possible if you need multiple for upgrades.
I’ve tested every supposed drop source for sealed tubes over the past two months, and only these four methods actually give you a legitimate shot at getting them. Skip any other methods you see floating around social media, because they’re almost always untested or outright fake.
- Elite enemy bounty missions: Most level 30+ bounties from the town commission board have a chance to drop sealed tubes as a bonus reward for completing the mission in under the time limit. Higher level bounties have a slightly higher drop rate, so prioritize level 40+ bounties if your roster is strong enough.
- Hidden research chests: Found in abandoned labs across the Jinzhou and Cloudrealm areas, these gold-marked chests have a 30% higher drop rate for sealed tubes than standard world chests. They respawn every 48 hours, so you can hit the same spots on repeat if you’re farming for a lot of tubes.
- Weekly rover challenge rewards: If you clear all 7 weekly rover challenge tiers, you’re guaranteed at least one sealed tube, plus a chance for extra drops from the final tier chest. This is the only 100% guaranteed drop source in the game right now, so don’t skip your weekly challenges if you need tubes fast.
- Side quest completion rewards: Specific tech-focused side quests from NPCs in the Research Institute area will give you 1-2 sealed tubes as a fixed reward for finishing them. You can only get these once per account, but they’re a great way to get your first few tubes without farming.
You don’t have to stick to just one of these methods, either. I usually mix bounty runs and research chest farming with my weekly rover challenges to get as many drops as possible each week. If you’re a casual player who only logs on a few times a week, focusing on the weekly challenges and fixed side quest rewards will be more than enough to get you the tubes you need.
The Fastest Farming Route for Sealed Tubes
If you need sealed tubes as fast as possible for a weapon upgrade or quest, this 45-minute route is what I use when I’m farming for multiple copies at once. It prioritizes the highest drop rate activities first, so you don’t waste time on low-chance tasks. I usually get 2-3 sealed tubes per run of this route, which is way faster than grinding random bounties for hours.
Start by picking up all three level 30+ bounties from the Jinzhou commission board first. Make sure you pick bounties that target elite enemies in the Cloudrealm area, so you can hit your research chest stops right after you finish each bounty. Don’t forget to pick up the bounty time bonus challenge before you leave the board, because that extra condition is what unlocks the sealed tube drop chance for the mission. If you don’t take the bonus, you won’t get a tube even if you beat the elite enemy fast.
After you finish all three bounties, hit the 8 hidden research chest spots along the northern edge of Cloudrealm. You can fast travel between the three nearest waypoints to cut down on travel time, and you don’t have to fight any extra mobs to reach most of these chests. A few of the chests are hidden behind breakable walls, so make sure you have a character with a blunt attack in your roster to break through them quickly.
Once you’ve cleared all the chests, turn in your bounties and claim your rewards. If you do this route once a day, you’ll have all the sealed tubes you need in less than a week, even with bad drop luck. I’ve had runs where I got 4 tubes in one go, and runs where I got none, but the average always evens out to 2-3 per run over time.
Common Mistakes That Waste Your Time Farming Sealed Tubes
I made almost all of these mistakes when I first started farming sealed tubes, so I know how frustrating it is to spend hours on activities that don’t even have a chance to drop the item you want. Avoid these errors to cut your farming time in half, and stop wasting resources on low-value tasks.
First, don’t waste time opening common white or blue chests. Only gold-tier research chests have a chance to drop sealed tubes, so standard world chests won’t give you what you’re looking for, no matter how many you open. A lot of new players assume all chests have the same loot pool, but that’s not the case for rare crafting components like sealed tubes. I wasted three days opening every chest I found across Jinzhou before I figured this out, and I didn’t get a single tube the whole time.
Second, don’t skip the time bonus condition for bounty missions. If you finish the bounty after the time limit runs out, you won’t qualify for the bonus reward pool that includes sealed tubes, even if you beat the elite enemy. I used to ignore the time limit all the time because I thought the extra reward was just common upgrade materials, and I wasted two whole weeks of bounties without getting a single sealed tube.
Also, don’t buy sealed tubes from player stalls unless you’re in a huge hurry. Most players mark them up 2-3x their actual value, and you can get them for free just by following the farming route I laid out earlier. It’s not worth spending your hard-earned in-game currency on something you can farm easily in a few days. The only time I’d recommend buying them is if you need one more tube to finish a weapon upgrade right before a big endgame raid, and you don’t have time to farm for it.
Finally, don’t waste sealed tubes on low-tier upgrades. I’ll talk more about this in the next section, but using a sealed tube on a 3-star weapon you’ll replace in 10 levels is a huge waste of a rare resource. Save them for endgame upgrades and quest unlocks, where they give you the most value.
What to Use Sealed Tubes For Once You Have Them
Sealed tubes aren’t just a random crafting material they have some of the most useful applications in the game, especially if you’re focused on endgame content. You don’t want to waste them on low-tier upgrades that you’ll replace in a few levels, so I always recommend saving them for these specific uses first.
The best use for sealed tubes is upgrading 5-star weapons to level 60 and above. Every 5-star weapon needs 3 sealed tubes per upgrade tier starting at level 60, and there’s no alternative material you can use for this step. If you have a main 5-star weapon you use for all your endgame content, prioritize saving your sealed tubes for these upgrades first before you use them for anything else. A fully upgraded 5-star weapon will make all endgame content way easier, so this is the best return on investment you can get with sealed tubes.
They’re also required to unlock some of the best hidden side quests in the Research Institute area. One quest in particular, the "Lost Research Data" line, requires 2 sealed tubes to start, and it rewards you with a free 4-star support weapon and 1000 primogems when you finish it. That’s a way better return on investment than using them for low-tier weapon upgrades that you’ll outlevel quickly. I always recommend doing these quests first once you get your first few sealed tubes, because the rewards are way more valuable than early game upgrades.
You can also use them to craft rare resonance amplifiers, which boost your character’s resonance damage by 15% for 30 minutes. These are really useful for endgame boss fights and rover challenge tiers, but I only recommend using sealed tubes for these if you already have enough saved for all your weapon upgrades. They’re too rare to waste on temporary buffs unless you’re swimming in extra copies. I keep a stack of 5 amplifiers on hand for hard boss fights, but I only make them once I have all the tubes I need for my main weapon upgrades.
If you have extra sealed tubes left over after you’ve upgraded all your main weapons and unlocked all the relevant side quests, you can sell them on the player market for a nice chunk of in-game currency. A lot of endgame players are willing to pay top dollar for sealed tubes, so this is a great way to make extra money if you have a surplus.
Farming for rare materials in Wuthering Waves doesn’t have to be a frustrating grind if you know exactly where to look and what activities to prioritize. Once you learn how to get sealed tube Wuthering Waves using the methods and route I laid out, you’ll be able to unlock all the best weapon upgrades and hidden quest rewards without wasting hours on low-value tasks. Don’t forget to avoid the common mistakes I mentioned, and you’ll have a full stock of sealed tubes in no time, no matter if you’re a free-to-play player or someone who spends money on the game. You’ll be shocked at how much easier endgame content gets once you have those 5-star weapons fully upgraded.
