Ansul RedLine Fill Cap w/ Indicator 17999

The Ansul 17999 is the OEM fill cap with built-in indicator for Ansul RedLine portable fire extinguishers. The fill cap seals the fill port between service intervals, and the integrated status indicator provides a visual confirmation that the unit is properly sealed and recharged — a quick-check feature that simplifies both monthly fire extinguisher inspection tag verification and formal annual service visits. The indicator allows technicians and monthly inspectors to immediately identify units that may have been partially filled or improperly closed after the last internal examination without removing the fill cap for a full pressure test.

The ANSUL RedLine is one of the most widely deployed professional-grade portable extinguisher lines in commercial and industrial fire protection. Proper fill cap integrity is fundamental to NFPA 10 compliance — a leaking or improperly seated fill cap causes slow pressure loss that may not register on the pressure gauge until significant propellant has been lost, potentially leaving the extinguisher incapable of full discharge when needed. The 17999 indicator adds an extra layer of assurance that complements the pressure gauge reading during monthly inspection tag checks between formal annual fire extinguisher service visits.

Keeping the 17999 and its companion 006190 fill cap gasket in van stock ensures complete fill port assembly service can be done during NFPA 10 internal examination visits without delay. After installing a new 17999 and 006190 gasket, update the fire extinguisher service tags and extinguisher tags per NFPA 10. The annual fire extinguisher inspection tags and extinguisher inspection tag records must reflect the fill cap replacement date and the technician who performed the service. Available through authorized ansul distributors as part of the ANSUL fire extinguisher service equipment catalog.

Inspect the 17999 fill cap and indicator at every NFPA 10 annual inspection and during monthly fire extinguisher inspection tag verification rounds. Replace the 006190 fill cap gasket at every internal examination — the fill cap itself should be replaced if cracking, corrosion, or indicator malfunction is found. Torque the 17999 to the ANSUL specification after installing a fresh 006190 gasket. Update the fire extinguisher service tags, extinguisher inspection tags, and extinguisher fire inspection tag records after any fill cap service. The tag for fire extinguisher inspection and the fire extinguisher service schedule records are reviewed by AHJ inspectors as primary NFPA 10 compliance documentation.

Is the fill cap gasket included with the 17999?

No. The 17999 fill cap is sold without the 006190 gasket. Always order both together for internal examination service — a new fill cap must be installed with a new gasket. Never reuse the old gasket when installing a new or existing 17999 fill cap. The o-ring lubricant recommended in the ANSUL service documentation should be applied to the 006190 gasket before installation.

How does the fill cap indicator help with monthly inspection tags?

The built-in indicator provides a visual status check visible during the monthly fire extinguisher inspection tag verification without requiring gauge reading or fill cap removal. If the indicator shows an abnormal state between formal annual service visits, the extinguisher should be flagged on the monthly inspection tags for priority service fire extinguisher near me scheduling before the next annual inspection date.
