Grommets

SPS offers many different grommets including pipe, tubing, and transmitter grommets, manufactured from our custom green silicone material. The grommets supplied are most commonly used for 1/8" to 7/16" wall thickness. The pictures below show many different size grommets installed into our standard enclosures. View the list below for all of our pipe and tube grommet standards.

The specially formulated gasket material stays flexible and sealed at 350 degree F. and above. Transmitters such as Honeywell 924 and 3000 series as well as Rosemount, Bailey and Foxboro have special designed grommets which are shown below.
