Expert Advice


"JEM has been a great company to work with over the years.  They are very reliable, easy to deal with, and produce quality products.  I have found their one on one style and expert advice so helpful when I am working on difficult projects.  I would not 

hesitate to recommend them to anyone I know." -Gabe W.

Time Saving Solution


JEM Custom Products was able to fabricate a reliable Charcoal Trap and Drain (for use in our Fuel In Oil Analysis - A Turn Key System) using our blueprints and specifications. This frees our customers to focus on the task of analyzing their samples as opposed to having to manufacture these traps by hand, something that is very time consuming and tedious. If not done correctly the work has to be done over, resulting in even more time being wasted . . . time that could be spent making money. Thank you for the great product and customer support! -Kerry L.
