1 Foot Long plastic plexiglass tubes, Clear acrylic PVC pipe transparent for 3 inch PVC fittings, 3 1/2 inch 89mm diameter tube, 1/10 inch thick tubing

This seems to be a very high-quality tube. It’s about half the thickness as schedule 40 PVC but it seems to be very strong. I can’t attest to the longevity or how it handles freezing temperatures because I just got it and because I live in South Texas. But this was exactly what I needed for an inspection tube for my sewer line. It works perfectly with 3” schedule 40 PVC pipe.

Either the product is different or people used the wrong PVC fittings. I used these for inspection windows in a very very long drain pipe to monitor if there's ever a problem. You'll notice I added clean out T and an elbow on either side also since it's 8-9x as expensive as the pipe I cut in half to get twice the windows. Cut with a band saw while careful turning so the blade is barely though the side. I goofed and shattered and had to cut about 3/4 inch extra off one half. I did the small cut using an angle grinder and diamond wheel so it would melt the edgd and leave no micro cracks. I will definitely use in the future.

I was nervous about the below comments regarding size. Well, it turn out that it fit 3 inch pvc well. Maybe the seller fixed the prior size issus? will buy this again. i am using this to set up my rain water collecting system. updated on 9.16.23 Bought 2nd one，again，fits perfectly with standard homedepot 3 inch pvc fitting. see picture i took. This is my custom made rain water collecting filter system. I dont see any issue regarding the prior comments of the size issue. i recommend this product

Well packaged and arrived on time. Perfect for my application.

Product was clear and strong. I used it on RV black tank discharge.

I bought this tube along as well as two(2) 3" PVC end caps that several reviewers verified fit standard schedule 40 PVC pipes. The diameter of this tube is TOO LARGE to fit inside the end caps. I'm going to try sanding the sides down, but this was not supposed to be necessary according to the product's description.

The inside measurement is 3 1/4. Not 3 inches as advertised.

As you can see micrometer shows the OD is a sixteenth in. over 3.5 in. required for fitting into a pvc fitting. Good luck trying.

Exactly as specified by the Amazon product description; fits standard 3 inch black PVC pipe. Perfect for my water display project.
