Amerex 7/8" Rubber Bumper Grommet (12 Pack) - 13958

The Amerex 13958-P012 is a 12-pack of 7/8" rubber bumper grommets — the OEM protective base inserts used across the Amerex portable fire extinguisher line. These bumper grommets serve two critical functions: they protect the bottom seam weld of the cylinder from impact damage when the unit is set down on hard surfaces, and they prevent metal-to-floor contact that can cause corrosion in wet or chemically aggressive environments.

In facilities with concrete, tile, or metal flooring — common in commercial kitchens, industrial plants, and warehouses — a fire extinguisher without a bumper grommet is subject to "fretting corrosion" where microscopic movement between the cylinder base and the floor surface gradually damages the protective coating. This is why bumper grommets appear on every NFPA 10 fire extinguisher maintenance tags review as a required component check. The Amerex 13958 12-pack ensures your service team has a sufficient supply for fleet-wide maintenance visits.

These grommets are manufactured from a durable rubber compound that resists the oils, cleaning chemicals, and temperature extremes found in commercial and industrial settings. They are a low-cost fire extinguisher accessories item that prevents expensive cylinder damage and inspection deficiencies.

When to Replace Bumper Grommets

Bumper grommets should be inspected during every annual fire extinguisher inspection. Replace the grommet if it shows cracking, hardening, deformation, or if it has separated from the cylinder base. A missing or deteriorated grommet is a deficiency that should be noted on the fire extinguisher inspection label and corrected before returning the unit to service.

Installation

The 13958 snaps into the recessed seat on the bottom of compatible Amerex cylinders. Ensure the seat is clean and free of debris before pressing the new grommet into place. The grommet should seat firmly without gaps around the perimeter. A poorly seated grommet can allow moisture to pool under the cylinder, accelerating corrosion at the base seam weld.

Bulk Pack Advantage

The 12-pack format is ideal for fire equipment maintenance services shops managing large extinguisher fleets. Keeping this fire extinguisher accessories item stocked ensures every unit serviced receives a fresh grommet without requiring a separate parts order, reducing service time and total fire extinguisher service costs.

Are these compatible with all Amerex extinguisher models?

The 13958 7/8" grommet is compatible with a wide range of Amerex portable fire extinguisher models. Always verify compatibility against the Amerex fire extinguisher parts list for your specific model before ordering, as some specialty units use different base configurations.

Can I use a generic rubber grommet from a hardware store?

While generic bumper grommets may appear similar, OEM parts are sized to precise tolerances to fit the Amerex cylinder base seat correctly. An incorrectly sized grommet will not seat properly and will not provide effective corrosion protection. Using genuine Amerex fire extinguisher parts and supplies ensures the correct fit and preserves the unit's service record integrity.
