I came across this site while trolling some other projects yesterday. They provide a lot of versatile options for PVC fittings. I am ordering some specialty fittings to upgrade my Photo Booth and I added some fittings in for a few DIYC projects ideas. One thing I already put in the cart were some inside End-caps for 1" PVC. I like the way these look compared to the normal Plumbing caps.

Sorry if this has been posted before.
