63MM Rieke Waste Collection Products
There are a host of thread variants in the 63mm diameter, and unfortunately most are incompatible with the others. This more common version utilizes the Rieke® 63mm threaded cap (check along the rim of the closure of your 63mm container - often “Rieke®” will be embossed on the top). Interestingly, an identical thread was also integrated into the NowPak® Liner-Based System by Entegris®.
Note that the Nalgene® Lowboy™ 63mm container is a slightly different thread; inquire for solutions.
