The U.S. Department of Defense created the National Stock Number system in order to create a uniform naming system for all the components that are sourced, stocked, and procured within the federal supply system. NSNs are 13 digit serial numbers that classify and describe an item. Within the NSN are the smaller classification numbers, Federal Supply Group, Federal Supply Class, country code, and National Item Identification Number. Typically in the format, XXXX-XX-XXXXXXX, the first two digits of the NSN are the Federal Supply Group. The following two digits are the Federal Supply Class. The FSG and the FSC can be referenced in the Department of Defense’s H2 handbook.

One of the federal supply groups that we carry is federal supply group 47. This is the group that encompasses all pipes, tubing, hose and fittings. Any time a military or government customer has a requirement involving any pipes, tubing, hose and fittings, we know to go directly to this federal supply group to provide for them.

FSG 47 is a group that consists of equipment and tools used to combat fires as well as be protected from fires. There are 6 different federal supply classes that make up the group FSG 47 which are:

Some of the equipment found under this federal supply group are pipes, tubing and rigid tubing. This includes anything from culvert pipes, culvert pipe connector bands, metallic pipes, plastic pipes, tubes and rigid tubing. Any of their assemblies fall into this group as well. Hose and flexible tubing include air ducts, metallic or nonmetallic and textile fiber hoses, flexible tubing, and all of their assemblies as well. Under this FSG you can also find hose, pipe, tube, lubrication and railing fitting, which would be FSC 4730.
