            Are these a permanent solution in an attic space? The max working temp is 120 f. I would imagine the attic is hotter than that in the summer. This is in Sacramento California.

              Hi Peter! To install, simply place over open end of pipe and tighten to 60" lbs. of torque.

                    Fits great on 2" PVC drain pipe.
                    I had to move the kitchen sink to the opposite wall and tap into the drain in the basement a little earlier on. So I got this 2" cap to close off the original drain line. It is all rubber and comes with the necessary clamp. Flexible and snugly fit my 2" PVC pipe. Clamp tightens down well and tight. Overall a really good deal and it works to close off a 2" drain line just fine. I am happy with the purchase..

                      This doesn't look like the image; where is the metal clip? No matter how thoroughly I checked the specifications, it doesn't say anywhere that it is sold separately.

                        I bought the 2 inch PVC Fernco cap to cap off a sewer drain. Fits correctly, hose clamp tightens down nicely. It seems to be strong and of good quality. I would recommend.

                        This was exactly what I needed to cap off an old dishwasher drain pipe. I used it a bit. Make sure you get the right size for your application.
