I have two small pieces of 2-1/2" SCHEDULE 20 that I found, but I need several longer pieces for a non-plumbing project. I want to make some pneumatic beer-can launchers (for aerial shooting practice). 2-1/2" schedule 20 is an ideal slip fit for a standard beer can.
The local Home Depot and Lowe's both say it doesn't exist until I show them my sample, but still can't get any for me. The samples I have are dark gray in color.
I've been looking for several years, off and on, and have never found a plumbing store that had this stuff.
thanks,
Martin
