Description
  • A duct connector designed to help cool and ventilate multiple spaces by redistributing airflow.
  • Y-shaped splitter maximizes the use of only one inline fan by branching your ductwork into two paths.
  • Smooth, rounded bending frees airflow to minimize wind resistance by reducing friction and turbulence.
  • Solid steel body with a powder coat finish that can resist corrosion and withstand high temperatures.
  • Fits 4" Duct Openings | Raised Lip for Greater Grip | Length: 10.90" | Finish: Powder Coat
  • Product Description: An air duct splitter designed to distribute airflow to multiple spaces for cooling and ventilation applications. The y-shaped duct connector allows you to use only one inline duct fan to provide airflow to two rooms. Its softly bent metal pipe joints and smooth interior surface provide low wind resistance resulting from friction and turbulence. Each duct port is built with raised lips for a greater grip on duct tubes when sealed with aluminum tape or clamps. A solid steel body construction rounds out the build, capable of resisting corrosion and withstanding high temperatures in HVAC settings.
  • Applications: This HVAC duct fitting branches ductwork into two paths to split supply of, return, or exhaust air in two rooms or other kinds of spaces. Select models can be used as a vent adapter to fit different sized ducting and inline fans together. Pair these components with 2 in 1 grow tents, or two separate grow tents, to simultaneously ventilate both chambers as an intake system. Other applications include whole house cooling, dryer vents, dust collectors, and other HVAC settings as an exhaust pipe splitter.

    good price for good product. applies well, shake and store upright
    Style: SPF 50, Size: 8 Fl Oz (Pack of 1), Style: SPF 50, Size: 8 Fl Oz (Pack of 1)
    I believe it is equal to the name brands It is 50 SPF Sun Protection Factor so it offers strong UV A and UV B protection which are the 2 ranges of sun rays that do the skin damage and burning. It is an easily absorbed lotion that when rubbed goes into the skin and is not visible. It is thick and goes on with a non shiny, non greasy, solid thick feeling which is what we need for it to stay on as long as possible. It feels good after being rubbed in in that it feels dry and not overly greasy or with no shine and sheen. It is a good product and offers burn protection to me in some clear-sky strong sun uses. Reapply after entering the pool water or swimming laps and after an hour (all sunscreen labels say reapply after 80 minutes which I believe is per recommendations of the federal FDA or some medical studies). I reapply often and I still get tanned but I do not want to burn.

    Survived the sun like a pasty legend
    Style: SPF 50, Size: 8 Fl Oz (Pack of 1)
    I bought this sunscreen because I’m basically a human marshmallow — one hour in the sun and I’m toasted. This Amazon Basics Sport SPF 50? It’s like armor for the pale and easily crisped. I slathered it on before a full day of hiking, sweating, and pretending I enjoy direct sunlight, and guess what? No burn. Not even a pink glow. Just victory. It goes on smooth, doesn’t feel greasy, and somehow stayed put through sweat, water, and my dog licking my arm. It’s fragrance-free, which means I didn’t smell like a coconut smoothie or a chemical spill — just clean and protected. Pros: • High SPF that actually works • Sweat and water resistant — like, impressively so • No greasy residue or weird smell • Affordable and comes in a big ol’ bottle • Didn’t turn me into a lobster (the bar is low, but still) Minor feedback: It’s not fancy or trendy, but honestly, I’m here to not burn — not win a skincare award. Also, it takes a bit of rubbing in, but once it’s on, it’s locked and loaded. Final thoughts: If you want solid sun protection without the drama, this stuff delivers. Whether you’re hiking, swimming, or just trying to survive summer, it’s a reliable sidekick. Would absolutely buy again — my skin demands it.

    Great Sunscreen at a Great Price!
    Style: SPF 50, Size: 8 Fl Oz (Pack of 1)
    Love this sunscreen. I live in FL and like to walk most mornings, and need a good sunblock. This Amazon Basics is far better than my previous, far more expensive brand. It's a great price for great quality. I've been using it on my body & face, it's non-greasy, absorbs well, and really seems to offer very good sun protection. And I really appreciate the next day shipping on my past two orders, Amazon. Thanks for the great product & great service!

    Works when working outside and heavy activities
    Style: SPF 50, Size: 8 Fl Oz (Pack of 1)
    I use it as an Amazon delivery driver, and it works in the heat and sweat is no issue it does last for 2 hours. Reapplying it is extremely easy, no burns or sun damage to my skin. I can tell you it works cause I’m recovering from skin cancer and it works no problems or anything.

    Just ok - too thick to apply evenly
    Style: SPF 50, Size: 8 Fl Oz (Pack of 1)
    Just ok - very thick, so difficult to apply evenly. I use this for outdoor cycling and it works, but it's so thick that it tends to clump instead of smoothly covering the skin.
