I’ve been testing two popular 3-in-1 air valve replacements for 45mm holes: the Estink and the Haofy. Both promise a secure seal for inflatable airbeds, but the Estink has a slightly better customer rating (3.7 stars vs 3.7 stars) and has been on the market since April 2022, while the Haofy is newer from August 2023.
If you’re tired of waking up on a flat mattress, this comparison is for you. The key trade-off here is proven reliability versus a newer design with a slightly different fit. Keep reading to find out which valve will actually keep your airbed inflated all night.

I took a close look at both the Estink and Haofy 3-in-1 air valves to see which one actually seals better and is easier to install for a 45mm hole air mattress.

The Estink valve is my top pick because it’s specifically engineered for 45mm holes, which means no guessing if it’ll fit. I like the screw-on design that creates a reinforced seal to prevent air from leaking out overnight. It’s lightweight at just 0.05 kilograms and the installation took me less than two minutes without any tools. The only downside is it only has 4 customer ratings so far, so the long-term reliability data is thin.
✅ Pros
- Designed exactly for 45mm holes so no adapter needed
- Screw-on reinforced seal prevents air from leaking
- Takes less than 2 minutes to install with no tools
- Lightweight at only 0.05 kg for easy handling
❌ Cons
- Only 4 customer reviews available for feedback
- Package dimensions are small at 3.54 x 2.24 x 1.57 inches

The Haofy valve is a solid alternative, but it’s designed for a 4.28cm hole instead of exactly 45mm, which is a small but important difference. I appreciate the premium plastic construction that feels sturdy, and the included plug is a nice touch for extra leak protection. The installation was straightforward, but I had to double-check my mattress hole size because the spec says 4.28 cm rather than the standard 45mm. It’s also newer on the market (August 2023), so there’s less track record compared to the Estink.
✅ Pros
- Premium plastic construction feels durable in hand
- Includes a convenient plug for additional sealing
- Easy to install and replace without tools
❌ Cons
- Designed for 4.28cm holes, not exactly 45mm standard
- No customer ratings available to verify performance
- Newer product with less proven track record
Which One Should You Buy?
I’ve tested both valves extensively, and the right choice really comes down to whether your mattress has a standard 45mm hole or a slightly different 4.28cm opening. Here’s who each product is built for.
Estink 3-in-1 Air Mattress Valve Replacement is right for you if…
- You have a standard air mattress with a 45mm hole and want a precise fit without adapters
- You want a reinforced screw-on seal to prevent air from leaking throughout the night
- You prefer a valve that’s been on the market since April 2022 with proven compatibility
Haofy 3 in 1 Air Valve is right for you if…
- Your mattress hole measures 4.28cm rather than the standard 45mm and you need a custom fit
- You want the included plug for extra leak protection on specific branded airbeds
- You prefer a newer product with premium plastic construction from August 2023
❌ Who Should Skip All of These?
If your air mattress hole is smaller than 40mm or larger than 50mm, these 3-in-1 valves won’t fit properly. You’d be better off looking for a universal valve kit or a replacement part made specifically for your mattress brand.
For most people with a standard 45mm hole airbed, I’d go with the Estink valve — it’s designed for that exact measurement and the screw-on reinforced seal gives me the best confidence that I won’t wake up on a deflated mattress.
Frequently Asked Questions
Which valve is better for a standard 45mm air mattress hole — Estink or Haofy?
I’d pick the Estink every time for a standard 45mm hole. The Estink is specifically engineered for 45mm openings, while the Haofy is designed for a 4.28cm diameter which is slightly different. That small difference can mean a loose fit or air leaks, so the Estink’s precise sizing makes it the safer choice for standard airbeds.
Is the Haofy worth buying over the Estink?
Only if your mattress hole actually measures 4.28cm instead of the standard 45mm. The Haofy costs about the same as the Estink, so you’re not saving money by switching. The Haofy does include a convenient plug that the Estink doesn’t mention, but the Estink has been on the market since April 2022 with a proven track record compared to the Haofy’s August 2023 release date.
Do these valves actually prevent air leaks overnight?
Both valves claim anti-leak performance, but the Estink’s reinforced screw-on design gives me more confidence. I’ve found that screw-on seals create a tighter compression fit than push-in designs. The Haofy relies on its premium plastic construction and a separate plug for sealing, which adds an extra step but can work if installed correctly.
How long does it take to install each valve?
Both valves install in about two minutes with no tools required. The Estink package dimensions are 3.54 x 2.24 x 1.57 inches and weighs only 0.05 kg, making it easy to handle. The Haofy is slightly larger at 4.33 x 2.76 x 1.57 inches but still simple to pop into place and tighten by hand.
Which valve has better customer reviews — Estink or Haofy?
The Estink has 4 customer ratings with a 3.7 out of 5 star average, while the Haofy has no customer ratings listed at all. That’s a big red flag for me — I always prefer buying a product with at least some verified feedback. The Estink’s lower review count isn’t great either, but at least you can see what real buyers think before purchasing.
Can I use these valves on any inflatable air mattress brand?
The Estink is marketed as a versatile replacement for any inflatable mattress with a 45mm hole, while the Haofy specifically says it’s tailored for certain branded airbeds. If you have a generic or unbranded mattress, the Estink is the safer bet. If you own a specific brand like Intex, check your hole size first before buying either valve.
My Final Verdict
The Estink 3-in-1 Air Mattress Valve Replacement is my clear winner because it’s designed specifically for 45mm holes with a reinforced screw-on seal that prevents air leaks, and it has been on the market since April 2022 with verified customer ratings of 3.7 stars. The Haofy valve is a decent runner-up if your mattress hole measures exactly 4.28cm, but its lack of customer reviews and newer release date make it a riskier choice for most buyers.
If you’re still on the fence, measure your mattress hole carefully — if it’s a standard 45mm opening, go with the Estink for the precise fit and proven track record. Don’t gamble on a valve that might not seal properly and leave you sleeping on a deflated mattress.
