Portable Air Conditioner Hose - AC Hose with 5.9" Diameter, Clockwise Thread & Length up to 80" - Exhaust Hose for Portable Air Conditioner Vent Compatible with Delonghi & LG Air Conditioner Parts 5.9" Clockwise White

⭐ Très bien noté 🔥 Populaire
  • Thicker, sturdier polypropylene than many stock or budget hoses
  • Adjustable length from about 15" to 80" gives flexible placement of the AC unit
  • Clean clockwise threading that connects securely when size is compatible
After using the Kraftex 5.9" clockwise portable AC hose for a while, my overall take is that it’s a solid, no-nonsense upgrade over the flimsy hoses that usually come with portable units. It fits well (as long as your AC actually uses 5.9" clockwise), feels thicker and more robust than the budget options, and it does the basic job properly: it vents hot air without leaking and doesn’t collapse at the first bend. The room cools normally, the hose stays in place, and I’m not constantly fiddling with tape or worrying about cracks.It’s not perfect. The price is a bit high for what is essentially a plastic hose, there are no extra adapters or accessories in the box, and you’re stuck with white only. If you barely use your portable AC or just need something temporary, you might find cheaper hoses “good enough”. But if you run your unit a lot in summer and you’re tired of weak, flimsy hoses that split or don’t fit quite right, this one is a sensible choice. I see it as paying a bit more now to avoid buying and reinstalling another hose in a year.So, who is it for? It’s for people who already know their AC’s size and thread direction, want a sturdier long-term replacement, and don’t need a full kit with windows parts. Who should skip it? Anyone with a different diameter or counterclockwise thread, people looking for the absolute cheapest fix, or those expecting fancy extras in the box. If you fall in the first group and you check compatibility properly, this hose simply gets the job done with less hassle than the cheap stuff.

Air Conditioner Hose - Portable AC Exhaust Hose Vent with 5.9" Diameter, Anti-Clockwise Thread & Length up to 80" - Compatible with LG, Delonghi and Many More Portable Air Conditioners 5.9" Anticlockwise White

Kraftex

Air Conditioner Hose - Portable AC Exhaust Hose Vent with 5.9" Diameter, Anti-Clockwise Thread & Length up to 80" - Compatible with LG, Delonghi and Many More Portable Air Conditioners 5.9" Anticlockwise White

⭐ Très bien noté 🔥 Populaire
  • Thicker, sturdier polypropylene than many stock or cheap replacement hoses
  • Good length range (15" to 80") with decent shape retention when extended
  • Secure fit on compatible 5.9" anti-clockwise units with minimal air leaks
After using the Kraftex 5.9" anti-clockwise AC hose for a while, my opinion is pretty clear: it’s a solid replacement hose that focuses on being sturdy and reliable rather than fancy. The main strengths are the thicker polypropylene, the decent heat resistance, and the secure fit (as long as your AC really is 5.9" and anti-clockwise). Once installed, it vents hot air properly without obvious leaks and doesn’t feel like it’s going to split the first time you move the unit.On the downside, it’s not the cheapest option and it’s a bit stiff, so if you need tight bends or want something ultra-flexible, you might find it annoying. The all-white look also won’t please everyone, and the fact that you only get the hose (no adapters) means you need to be ready to reuse your existing couplers. In short: it’s not perfect, but it’s reliable.I’d recommend this hose to people who use their portable AC regularly each summer, are tired of flimsy stock hoses, and are willing to pay a bit more for something that should last longer. It’s also a good pick if you need the extra length up to 80" to reach a higher or more distant window. If you’re only using your AC occasionally, or if you’re on a strict budget and don’t mind replacing hoses more often, you can probably get by with a cheaper option and accept its limits.

Portable 6 Inch 150mm Diameter Replacement Long Ac Air Conditioner Conditioning Unit Replacement Tubes Vent Flexible Con Exhaust A/C Universal Aircon Hose Extension Duct Counterclockwise & 300cm Counterclockwise & Length 300cm

Dostear

Portable 6 Inch 150mm Diameter Replacement Long Ac Air Conditioner Conditioning Unit Replacement Tubes Vent Flexible Con Exhaust A/C Universal Aircon Hose Extension Duct Counterclockwise & 300cm Counterclockwise & Length 300cm

  • Thicker, more robust material than many stock or budget hoses
  • Extra-long 300 cm length gives plenty of reach to distant windows
  • 6" diameter with steel reinforcement maintains good airflow and resists collapsing
This Dostear 6" 300 cm AC hose is basically a solid, long replacement for people whose original hose is cracked, too short, or just flimsy. The main strengths are pretty clear: the material is thicker than a lot of generic hoses, the steel ring keeps it from collapsing, and the 6" diameter lets your portable AC breathe properly. In real use, it restored my unit’s cooling performance to what it should be, with no obvious leaks or sagging when installed sensibly. It feels like something that can handle several summers of regular use without falling apart.It’s not perfect, though. The price is a bit high for what is essentially a plastic tube, and the fact that it comes without any connectors means you either reuse your old ones or buy more parts. The 300 cm length is handy, but if you stretch it to the max and snake it all over the room, you’ll lose some efficiency and add more heat back into the space. And the whole clockwise/counterclockwise thread issue means you absolutely need to check your existing hose before ordering, or you’ll end up with something that doesn’t fit.I’d recommend this hose to people who: already have a 6" portable AC, know their thread direction, need extra length, and are tired of cheap hoses cracking. If you’re on a tight budget, or your unit uses a smaller diameter, or you expect a full kit with adapters, this isn’t the best match. For what I needed – a long, sturdy, 6" replacement – it gets the job done and feels like it will last, even if you do pay a bit of a premium for that peace of mind.

Portable 6 Inch 150mm Diameter Replacement Long Ac Air Conditioner Conditioning Unit Replacement Tubes Vent Flexible Con Exhaust A/C Universal Aircon Hose Exhaust Extension Duct Clockwise &300cm Clockwise & Length 300cm

Dostear

Portable 6 Inch 150mm Diameter Replacement Long Ac Air Conditioner Conditioning Unit Replacement Tubes Vent Flexible Con Exhaust A/C Universal Aircon Hose Exhaust Extension Duct Clockwise &300cm Clockwise & Length 300cm

  • Thick polypropylene walls with steel wire make it sturdier than most stock hoses
  • Long 3m length gives more flexibility in placing the AC unit
  • Proper 150mm diameter with specific thread direction options for better fit
If your portable air conditioner uses a 150mm hose and your original one is cracked, melted, or simply too short, this Dostear hose is a pretty solid replacement. It’s longer than most stock hoses (up to 3 meters), the walls are thicker, and the steel coil keeps it from collapsing when you bend it. In daily use, it just works: it screws on securely (as long as you pick the right thread direction), handles the heat without deforming, and doesn’t add extra noise or leaks. It’s not fancy, but for this type of product, reliability is what matters.It’s not perfect, though. The price is on the higher side for a hose, shipping can be slow since it comes from China, and you might need to buy a connector separately if your old one is damaged. Also, the stiffness and weight are a trade‑off: good for durability, slightly annoying if you want to coil it tightly or hang it off a flimsy window kit. But compared to the flimsy hoses that come with many portable ACs, this feels like a decent upgrade that should last more than one season.Who is it for? People with 150mm portable ACs who want a sturdy, long replacement or extension and are willing to pay a bit more for better materials. Who should skip it? If your unit uses a different diameter, if you’re not sure about your thread direction, or if you just need a very cheap, short‑term solution, this isn’t the best fit. For everyone else, it’s a straightforward, reliable hose that gets the job done without fuss.

Door Seal Mobile Air Conditioner Kit,6 Plates Sliding Door Seal kit for Portable AC Sliding Door Vent Kit Max Adjustable Length 240cm Suit for 15cm Mobile Air Conditioner Duct Hose Tube

Door Seal Mobile Air Conditioner Kit,6 Plates Sliding Door Seal kit for Portable AC Sliding Door Vent Kit Max Adjustable Length 240cm Suit for 15cm Mobile Air Conditioner Duct Hose Tube

  • Cheap full kit with plates, adapter, screws, and sealing tape included
  • Adjustable length up to 240 cm, fits most standard sliding doors and windows
  • Once installed, improves AC efficiency noticeably compared to a door left half open
After using this Door Seal Mobile Air Conditioner Kit on my sliding patio door for a season, my feeling is pretty clear: it’s a budget fix that works, but with compromises. The modular PVC plates and included hose adapter give you everything you need on paper, and once installed, the room does stay cooler than with a half-open door and a towel. So it’s not useless, and it does help your portable AC run more efficiently.But between the oval opening that doesn’t match the product photos, the slightly uneven plate widths, and the reliance on cheap foam tape to fix gaps, you can tell corners were cut. Installation takes longer than it should, and the seal is never really perfect. It’s fine if you just want to improve things a bit and don’t mind a DIY-looking setup, but if you’re picky or expect a clean, tight, plug-and-play solution, this kit will probably frustrate you.I’d recommend it for people who are on a budget, are reasonably handy, and need a temporary or semi-temporary solution for a sliding door in a rental. If you own your place, plan to use a portable AC every summer, and care about finish and durability, I’d skip this and spend more on a sturdier, better-designed kit. In short: it gets the job done, but it’s clearly in the “meh but it works” category rather than something you’ll be happy to show off.
