Birzman Issues Safety Recall of Tubeless Inflators Sold Since 2017

Jan 20, 2021
by Alicia Leggett  

Birzman has issued a safety recall of all Pump Up Tubeless Inflators (BM17-PUMP-UP and BM20-PUMP-UP) sold since 2017.

The pumps are designed to be inflated to high pressures, then to release that air quickly in order to seat tubeless tires. The problem identified is that if condensation builds up inside the canister, it can weaken the adhesive holding the canister together and can cause the product to “leak air, disassemble, or result in personal injuries."

A statement from Birzman:

To our Birzman community, the safety of our customers is and will always be our highest priority.

We have identified a potential safety issue: the condensation of moisture produced on the inside of the inflator during the release of high-pressure air may affect the adhesives used on the upper and lower covers, and this could impact the life-span of the product. External factors including humidity of the storage environment, atmospheric pressure and inflation over the limit may contribute to the acceleration of this outcome.

Under incorrect use such as inflating the product over the 220psi limit, the product could leak air, disassemble, or result in personal injuries.

The use of Pump Up Tubeless Inflators of either versions (BM17-PUMP-UP & BM20-PUMP-UP) should be stopped immediately.

We sincerely apologize for the situation, it was neither foreseeable nor actively avoidable. On behalf of the Birzman team, we would like to thank you for your support.

Retailers should remove these products from stock. Customers should stop use immediately. More details will follow about the recall procedures "within approximately 4 weeks."

 Air compressors solved this with a sticker. ‘Drain and dry monthly’
Ask all purchasers to mail in proof of purchase, mail them a warning sticker and a shipping label for a buyback if they don’t want the product.

Always assume anything sharp, pressurized, or heavy can kill you if you’re a moron. Don’t be a moron.

 This is what I thought. Is it not standard to remove condensation from your compressor? This would be no different.

 This what happens when companies have to push the limit with every product, the fact is the consumerism (driven by the industry mind you) results in crappy products meant to last a year or two, and engineers forget how to do their job. Yeah things get better as a whole, but this again just makes the old tech obsolete. BUT, buying new and improved stuff is fun and part of the sport, so can't live with it, can't live without it type of scenario.

 The "not foreseeable or avoidable" thing really pisses me off. I'm a reliability engineer with a background in pressure vessels. Any competent company would have seen that this design is inherently flawed. By attaching plastic plugs to the end of a tube with adhesive, you're subjecting a bunch of materials with different coefficients of thermal expansion, strengths, and stiffnesses to cycling thermal and mechanical stress.

Even if you lack the engineering foresight to see this coming, that's what reliability testing is for. This isn't some corner case test that you might miss. It's just basic usage cycles, maybe with some temperature and humidity variation. It doesn't get any more basic than this.

If anyone got injured and wants to sue them, lemme know. I'd be happy to testify as an expert witness.

 No need for anyone to be injured, so expect a call from the guys suing Trek over the Bontrager Wavecel helmets.

 And how low is their safety factor? Their max pressure rating should be able to be exceeded well beyond the point that the random dumbass would dare go. Epoxy vs. whatever cheap rubber cement the factory decided to use.

Furthermore, not forseeable??? Why TF do you think compressed air systems filter condensation ad infinitum??
  • 1 0
 @MartinKS: Yeah, I sent it to my team with the comment - "huge FMEA failure here"
  • 1 0
 @iamamodel: In my humble opinion, the Wave-cell suit is kinda a cash grab. While other's couldn't replicate treks safety findings, the helmet wasn't putting anyone in danger, rather just picking their pocket. So yeah, while trek may be responsible for the 5 mil settlement its a bit ridiculous.
  • 1 0
 @ehvahn: Agree. They were some of the top independently-rated helmets when launched. Plus, if anyone is picking pockets, it's the companies selling EPS helmets, which cost pennies to make, for hundreds of dollars. And contrary to some of the opinions here, you do actually have to demonstrate damages to win a lawsuit.

 @ehvahn: @natty: Don't get me wrong, my sarcasm isn't translating. That kind of suit makes my blood boil. And it's Summer here in Australia and I wear a suit to work, so I have experienced suits that make my blood boil, ha ha.

 It's not funny when they blow up in a confined space, trust me. Just get an airshot and enjoy being able to hear.

 @pbuser2299: I would not dare to use one in a confined space or without ear/eye protection, always treat pressure vessels as explosives. As this recall proves, these ready made canisters are just giving people a false sense of security.

 "disassemble" LOL - did they have Dick Cheney write their press release?

 Yeah, gluing the ends of a pressure vessel in place was a foreseeably terrible idea.

 Ive had one of these for at least 2-3 years now and it has been leaking air at high pressure for the last year over which I used it at least 5-6 times. I guess I'ĺl stop using it now.
  • 1 0
 So what would happen to my upper and lower covers if moisture condensates on the inside of my inflators during the release of high-pressure air? would my adhesive be at risk?
