Ansul RedLine Fill Cap Gasket 006190

The Ansul 006190 is the OEM replacement fill cap gasket for Ansul RedLine portable fire extinguishers, the ANSUL R-102 system, Checkfire systems, and 150 wheeled extinguisher configurations. The gasket creates the pressure seal between the fill cap (17999) and the extinguisher body's fill port — holding full operating pressure without leakage throughout the service interval. A compressed, cracked, or contaminated gasket causes slow fill port leakage that can deplete the propellant charge without being detected during routine monthly fire extinguisher inspection tag checks between formal annual service visits.

The 006190 is a mandatory replacement at every internal examination per NFPA 10. As a critical fire extinguisher service equipment consumable, it should be treated as single-use — a previously compressed gasket cannot reliably reseal to the original torque specification after removal. Fire extinguisher service shops managing ANSUL fleet accounts should keep the 006190 in van stock alongside the 17999 fill cap, o ring supply items, and extinguisher inspection tags to ensure complete fill port service during NFPA 10 internal examination visits. An improperly sealed fill port requires documenting the deficiency on the extinguisher inspection tag and correcting it before the fire extinguisher service tag can be signed off.

After installing a new 006190 and torquing the 17999 fill cap, update the fire extinguisher service tags and extinguisher tags to reflect the service date and gasket replacement. The monthly fire extinguisher inspection tag should be reviewed at the next monthly inspection to verify the fill cap is fully seated and the fill port shows no evidence of leakage. The tag fire extinguisher records required by NFPA 10 serve as the primary documentation reviewed by AHJ inspectors — complete and accurate extinguisher service tags are a compliance requirement at every NFPA 10 fire extinguisher service schedule interval. Available through authorized ansul distributors.

Replace the 006190 at every 6-year and 12-year internal examination per NFPA 10. Clean the fill port seating surface, install the new 006190, and torque the 17999 fill cap to the ANSUL specification. Pressure-test the fill port for leaks before returning the extinguisher to service. Update all fire extinguisher service tags, extinguisher inspection tags, and annual fire extinguisher inspection tags to document the replacement date and technician. The extinguisher fire inspection tag is the primary NFPA 10 compliance record reviewed by AHJ inspectors — it must accurately reflect every component replacement performed during the fire extinguisher service schedule.

How does a failed fill cap gasket affect the extinguisher service tag?

A failed fill cap gasket found during annual inspection requires documenting the deficiency on the inspection tag for fire extinguisher, performing the 006190 replacement, and signing off the corrected extinguisher inspection tag before the unit is returned to service. The monthly inspection tags should note any fill port moisture or pressure gauge anomalies that could indicate gasket failure between formal annual service visits. Complete inspection tags for fire extinguishers are required by NFPA 10 and are the first document reviewed during AHJ inspections of fire extinguisher service records.

Is the 006190 compatible with the ansul 3/4 hose gasket application?

No. The 006190 is a fill port cap gasket — a different component from the hose nozzle o ring or distribution line gaskets. While both are ANSUL gasket components, they serve different sealing positions. Always verify the correct o ring supply or gasket part number for each sealing position using the ANSUL fire extinguisher parts documentation.
