Genuine Amerex OEM O-ring, part number 13305, for Amerex Halotron I clean agent extinguishers with brass valves. This green O-ring is made for Halotron service. Use the correct O-ring for clean agent units rather than a standard dry chemical O-ring.
Replace this O-ring any time the valve is removed from the cylinder, including during recharge, hydrostatic testing and six-year maintenance. Using the genuine OEM part keeps your service work consistent with the manufacturer's service manual.
