I love how the inner diameter is less than the outer diameter to keep the air on the inside! Great duct for all your ducting needs.

Product arrived within a few days. I have no complaints.

Great Air duct, Price is comparable to other sources. No problems.

Excellent quality, double sided thickness. Much better than the old stuff.

Excellent quality, better than the one I had.

Fit perfectly. Good quality.

Exceeded my expectations. Much better than SCAT and well worth the added expense

Aircraft Spruce is a topnotch organization in my experience. Products are accurately represented, fairly priced, and shipped without delay. A highly satisfactory and recommended organization! Andy Anderson

I used this product to the replace the old broken ducting on my Porsche 911SC heat exchanger. Is was a perfect fit for my car.

Great substitute ducting for scat, the sceet with smooth bore giving a smoother airflow and stronger straighter installation.

Perfect replacement for a single wall SCAT tube used for a fuel injector air intake that had developed a tear.

Very durable and working great on my airplane

Outstanding service and quality of product many products offered that are not readily available elsewhere. Will definitely look here first for similar needs in the future.

Better than my original SCAT tubing. But it a little bit less flexible so order a bit long to allow for that. Worth it over the lesser quality tubing.

It was just as described and works great for my carb heat on my Hummel H5

High quality ducting

This is high quality ducting hose!! Its not cheap, but it appears to be worth the extra money. It is still flexible enough, but a little stiffer than SCAT. I recommend it.

Quality product. Very satisfied.

Very good product, just as all the others I have purchased over the many years of homebuilding.

An improvement over the original tubing for the RV-12 with the engine cooling shroud. (Early version of the RV-12. Should last longer with a smoother inside.

Perfect fit! Excellent product!

Exactly what I needed.

This was a great fit and the correct product I needed

Superior in handling and in service life, due to both construction and material. In over twenty years I have never seen silicone rubber degrade in hot or cold air tubing. Also, the double layer prevents the support spring from rusting or uncoiling, and if the outer layer chafes through, the hose can continue in service as long as the cause of the chafing is cured! Lastly, most of us have STRUGGLED with the coil unwinding, making us curse the day single layer tubing was created!

I was asked to write a review of this duct, so I shall: The duct does indeed, duct air, as advertised! I am giving it 4 not 5 stars because after about 5 years of medium-duty use and some connects and disconnects for maintenance, it does need to be replaced. Maybe that is not great, but only just good?

received the items, they were as I wanted.

Good quality in appearance, should hold up fine. One small issue is that the wire will not pull out from between layers without damaging the material when preparing the ends for clamps.

I ordered 3 ft only received 26 inches. Called and let them know I was short. Received the 3 feet plus a bill for another 3ft. Customer service not so great.

The tubing itself is great but was cut about 1/2� shorter than what I ordered. When I called customer service, the gladly sent me another....it was cut short too. My advice is if you need the full length, order an extra foot for insurance.

Worked for what we are trying to do but this is NOT a SCEET equivalent- and we ordered SCEET. Take a look at the spec sheets... for most applications Vena is fine but if you need higher pressures and temperatures, it isnt. The problem here is that Spruce thinks it is an equivalent product - we werent even asked about the substitution.

this product is NOT quality.....buy the other SCEET-5. mine failed at altitude in the Lancair and caused major headaches. light rubbing rubs off to show spring material. JUNK.
