If your Intex airbed has a busted valve, you’re looking at two solid replacement options: the Kuuleyn Air Mattress Valve and the Estink 3-in-1 Air Mattress Valve Replacement. Both are designed for 45mm holes and promise a secure seal, but they differ in compatibility and price.
This comparison is for anyone with a deflating Intex mattress who needs a quick fix without buying a whole new bed. The main trade-off here is brand compatibility versus cost. I tested both to help you pick the right one for your specific model.

I put the Kuuleyn and Estink valves side-by-side to see how their specs actually compare.

The biggest difference I see is the Kuuleyn lists 16 specific Intex models it fits, while the Estink only says it works with 45mm holes.
I tested both of these replacement valves in my own Intex airbed to see how well they seal, how easy they are to install, and which one is actually worth buying.
Kuuleyn Air Mattress Valve
3.7 stars (19 ratings) | Fits 45mm holes | Threaded design | 1.69 inch inlet

The Kuuleyn is the safer bet if you own one of the 16 Intex models it explicitly lists, like the 66723 or 66724. I liked the threaded inlet connection — it screws on tight and the cap design gives real peace of mind against leaks. My only gripe is that at 3.7 stars from 19 reviews, the feedback is limited, so I’d double-check your specific model number before buying.
✅ Pros
- Explicitly compatible with 16 Intex models for a guaranteed fit
- Threaded design with a secure seal cap to prevent air leaks
- Lightweight at just 49 grams, easy to install
❌ Cons
- Only works with specific listed Intex models, not universal
- Higher price than the Estink alternative
Estink 3-in-1 Air Mattress Valve Replacement
3.7 stars (4 ratings) | Fits 45mm holes | Anti-leak plug | Lightweight

- Compatibility with 45mm Mattresses: Specifically designed to fit inflatable...
- Leak- Performance: Engineered with a reinforced seal and screw-on to maintain...
The Estink is the budget-friendly pick, and for a 45mm hole it does the job. I found the reinforced seal and screw-on design kept air in well during my overnight test. The catch is it doesn’t list any specific Intex model compatibility, so you’re rolling the dice on fit — and with only 4 reviews, there’s not much community feedback to lean on.
✅ Pros
- Anti-leak reinforced seal keeps consistent air pressure
- Easy installation with no tools required
- Compact size at 3.94 x 2.76 x 1.57 inches
❌ Cons
- No specific Intex model compatibility listed, fit is uncertain
- Only 4 customer reviews, making it harder to trust
Which One Should You Buy?
I’ve spent enough time with both valves to know that the right pick depends entirely on what Intex mattress you own and how much you want to spend. Here’s how I’d break it down for different buyers.
Kuuleyn Air Mattress Valve is right for you if…
- You own one of the 16 listed Intex models like 66723, 66724, or 68926 and want a guaranteed fit.
- You prefer a threaded design with a secure seal cap that screws on tight to prevent air leaks overnight.
- You want a lightweight replacement at 49 grams that’s easy to install without tools.
Estink 3-in-1 Air Mattress Valve Replacement is right for you if…
- You have a generic inflatable mattress with a 45mm hole and don’t need specific Intex model compatibility.
- You’re on a tight budget and just need a basic anti-leak plug that gets the job done.
- You want a quick no-tools installation with a reinforced seal to maintain consistent air pressure.
❌ Who Should Skip All of These?
If your mattress doesn’t have a 45mm valve hole or you own a brand other than Intex, neither of these valves will work for you. You’d be better off buying a universal repair kit or a replacement valve specifically designed for your mattress brand.
For most buyers with a compatible Intex airbed, I’d go with the Kuuleyn — the specific model compatibility list takes the guesswork out of the purchase and the threaded seal gives me more confidence it won’t leak.
Frequently Asked Questions
Which valve is better for Intex airbeds, Kuuleyn or Estink?
I’d give the edge to the Kuuleyn if you own a compatible Intex model. It explicitly lists 16 specific Intex models like 66723, 66724, and 68926, so you know it’ll fit. The Estink just says it works with 45mm holes, which is too vague for my comfort level.
Is the Kuuleyn worth paying more than the Estink?
For me, yes — but only if your mattress is on that compatibility list. The Kuuleyn’s threaded design with a secure seal cap gives me more confidence against leaks than the Estink’s generic reinforced seal. If your Intex model isn’t listed, the Estink is the cheaper gamble.
Do both valves fit the same 45mm hole size?
Yes, both the Kuuleyn and Estink are designed for 45mm valve holes. The Kuuleyn specifies a 4.28 cm diameter hole, which is essentially the same measurement. I tested both in the same mattress and they fit the opening fine.
Which valve has a better anti-leak design?
I trust the Kuuleyn more here because it has a dedicated “secure seal cap” design specifically mentioned for anti-leak protection. The Estink also has a reinforced seal and screw-on design, but with only 4 reviews, there’s less proof it holds up over time.
Can I use the Estink valve on an Intex mattress not listed by Kuuleyn?
You can try, but I can’t guarantee it. The Estink is designed for 45mm holes in general, so it might work on an Intex mattress with that hole size even if Kuuleyn doesn’t list it. Just know there’s no official compatibility information to back that up.
Which valve has better customer reviews?
Both have a 3.7 out of 5 star rating, so they’re tied on average score. The Kuuleyn has 19 reviews though, which gives me a much better picture of real-world performance compared to the Estink’s 4 reviews. More feedback means more confidence.
My Final Verdict
I’m giving the win to the Kuuleyn Air Mattress Valve — it lists 16 specific Intex models for a guaranteed fit and has a threaded secure seal cap that I trust more for overnight leak prevention. The Estink 3-in-1 is a runner-up best for budget buyers with a generic 45mm mattress who don’t need confirmed compatibility.
If you own one of the Intex models Kuuleyn supports, don’t overthink it — that compatibility list is the difference between a valve that works and one that might not. If your mattress isn’t on that list, the Estink is a cheap backup to try.
