They are excellent for handling a variety of liquid streams containing a variety of solids - filters, sorbents, desiccants etc. They can also be used as small pressure vessels. They will hold pressure as advertised as long as you use PTFE tape or silicone vacuum grease on the threads. Good product. If you need a 3 port filter instead of 2, try a reverse osmosis water filter housing.
