Product Description

Product Description

A rubber clamp designed to connect duct ports with a secure and airtight grip to prevent any loss of airflow. The nitrile butadiene rubber structure fits smoothly over ports and piping thanks to its flexible and adaptable build. The heavy-duty rubber construction also suppresses noise and vibrations by absorbing sound waves, creating a quieter growing or HVAC environment. To ensure an even tighter connection, you can adjust the stainless-steel fasteners with worm drive locks, which are built into ribbed grooves along the rubber clamp to lock it in place.

Applications

I got this for a 4" exhaust fan in a small grow box and it works great. I have it in between the fan and a carbon filter. The rubber is very thick and does a great job of reducing noise from vibrations of the fan. The clamps that come with it are solid and keep a tight seal on the fan and filter.All of their products are fairly priced and this is no exception. Quality product at a great price makes this a must have. Nothing to dislike about this product whatsoever.

Very well made, easy to install, and makes joining my inline duct fan to the pipe much easier. I take the fan off about once a year to clean it...had been re-securing with foil tape each time, but now I can just un-clamp and re-clamp these fittings to remove the fan. Also helps in reducing the noise vibration from the fan. Diameter is good for 4" applications.

AC Infinity’s products are once again the top of their field. Competition doesn’t come close. So much easier than using and wasting tape over time and time again, Highly recommended. Does it Dampens the vibrations/Noise? Clearly makes great common sense with the quality materials used.

If you’re doing ductwork, these things work amazingly well. If you have two crimped ends that need to fit, it’s no problem. Regular full size ends fit just as well. A big bonus is that they knock down the noise. The only downside is that I don’t like their clamps because the bolt seems metric, but a standard screwdriver usually works just fine.

For making the connection to the inline fan and filter a breeze, not to mention Rock Solid! Remember no need to go "The Hulk" on it. Nice and snug, don't over tighten and squish the rubber out of shape.

Definitely helps for a good quality seal. Little bit of a pain if your connected something flexible (like a hose) using this. But for hard connection to hard connection. Works great

Used this between a whole house HEPA filter and the HVAC duct. It eliminated the annoying hum.
