The grommet is made from black synthetic rubber that conforms to MIL-G-3036 for use in demanding environments. The material resists hot oil and coolant exposure and maintains flexibility in service. It is designed for installation in bulkheads and firewalls to shield tubing, wiring, and control cables from abrasion at the edges of cutouts. The design follows MS35489 series geometry, using an annular groove that seats in the panel to secure the grommet. MS35489 series grommets and AN931 grommets of matching dimensions are fully interchangeable in service. The groove width is 1/16 inch, supporting secure retention in appropriately sized panel thicknesses. Multiple dash sizes within the series provide a range of hole diameters, outside diameters, and section thicknesses to suit different hardware and clearance requirements.
