Our Examples of Custom Products

Custom Studs

Marathon Oil in Mandan, North Dakota was in need of 1 3/8″ X 10 1/2″ B16 studs with a same-day turnaround request. They contacted Flowmark just after 8 a.m. and we were able to get the studs cut and on a hot shot to the refinery by 10:30 a.m. that morning.

Custom Gaskets

In 2018, the Big Equipment Company, LLC in Havre, Montana burned to the ground. There were no injuries but their 38,000-square-foot facility was destroyed. Also lost in the fire were any records of the gaskets they used for a particular twin disc motor. Fortunately, Flowmark had records on all the gaskets and we cut a dozen of each of the 32 gaskets on file in a day to get them back up and running.
