Wholesale PricingThe Amerex 14268 is the OEM collar o-ring for the aluminum valve assembly used on Amerex Halotron I portable extinguishers. Sold in a pack of 12, this green-coded seal is the collar o-ring replaced whenever the valve is disassembled during a scheduled internal maintenance service or following discharge when the unit is recharged. The collar o-ring seats between the valve body and the cylinder neck, creating the primary pressure seal that keeps the unit charged between uses.
Amerex specifies that only factory OEM parts be used during service, noting explicitly in their service manuals that substitute or aftermarket o-rings, even those labeled as compatible, do not meet UL component requirements and their use voids the extinguisher's listing and warranty. The 12-pack format is sized for shops and technicians servicing multiple Halotron I aluminum valve units in a single service run.

- Replace at Internal Maintenance or Recharge: Replace the collar o-ring whenever the valve is disassembled, which is required at the 6-year internal maintenance examination under NFPA 10 and following any discharge when the unit is recharged. Per Amerex's service manual, lightly lubricate the new o-ring with Visilox V-711 silicone grease before installation and clean the o-ring seating groove in the cylinder neck before seating.
- OEM Parts Only: Amerex explicitly voids the extinguisher's warranty and UL listing if non-OEM o-rings are used. Use only genuine Amerex P/N 14268 for aluminum valve Halotron I models.
- Leak Check After Installation: After reassembly and recharge, verify there are no leaks at the valve orifice or around the collar seal using a halogen leak detector or an appropriate leak detection solution.
- Confirm Model Compatibility: Aluminum-valve and brass-valve Halotron I models use different collar o-rings. Confirm your extinguisher's valve type matches this part before servicing.
Why does the color coding matter?
Amerex color-codes o-rings to help technicians quickly confirm they are installing the correct seal for the specific valve and agent type. The green collar o-ring for aluminum valve Halotron I models is distinct from o-rings used on dry chemical, CO2, or brass-valve Halotron units. Grabbing the wrong color from a service kit is a common field mistake this coding is designed to prevent.
Can I use a generic o-ring of the same size instead?
No. Amerex's service documentation explicitly states that generic, off-the-shelf, or substitute o-rings, including those marketed as Amerex-type, do not meet UL requirements and their use voids the extinguisher's listing and warranty.
Is there a different o-ring for brass valve Halotron I models?
Yes. Brass valve Halotron I models use a different collar o-ring, Amerex P/N 13305. Confirm your extinguisher's valve type before ordering.
