Ansul 30lb Cartridge Cover for RedLine - 418025

The Ansul 418025 is a protective cartridge cover for 30-lb ANSUL RedLine cartridge-operated fire extinguishers. The cover shields the cartridge housing from physical damage, impact, and environmental exposure during use, transport, and storage — protecting the puncturing mechanism and cartridge assembly that initiates agent discharge when the extinguisher is activated. The RedLine series is one of ANSUL's most widely specified professional-grade cartridge-operated fire extinguisher lines used in industrial, commercial, and institutional fire protection programs.

Cartridge cover integrity is an NFPA 10 annual inspection consideration — a cracked, missing, or deformed cartridge cover on a RedLine extinguisher exposes the cartridge assembly to mechanical damage risk from handling and incidental impacts. A cartridge puncturing mechanism that has been damaged by an unprotected impact may fail to fully puncture the cartridge during an emergency discharge, resulting in delayed or incomplete agent release. The 418025 OEM cover maintains the factory-specified protection for the cartridge housing and keeps the extinguisher compliant with ANSUL RedLine service specifications.

For fire extinguisher service shops managing ANSUL RedLine 30-lb cartridge-operated extinguisher fleets, the 418025 cover should be inspected at every NFPA 10 annual inspection and replaced if cracking, deformation, or missing hardware is found. Available through authorized ansul distributors as part of the ANSUL fire extinguisher parts service catalog. The ansul fire suppression system parts documentation and RedLine service manual provide the complete cartridge cover inspection criteria and replacement procedure. Document cover condition on the extinguisher inspection tags at every annual service visit.

Inspect the 418025 cartridge cover at every NFPA 10 annual inspection. Check for cracks, impact damage, deformation, and secure fastening to the extinguisher body. A cartridge cover showing any crack — even hairline — must be replaced before the extinguisher is returned to service. A cracked cover provides inadequate protection for the cartridge assembly, especially in industrial environments where the extinguisher may be bumped or dropped during monthly inspection checks. Replace with a new 418025 OEM cover, update the extinguisher inspection tags to document the replacement, and verify the cover is fully secured before returning to the mounting bracket. The cartridge cover condition should be noted on the fire extinguisher service tag at every annual visit.

Is the 418025 specific to the 30-lb model only?

Yes. The 418025 cartridge cover is sized for the 30-lb ANSUL RedLine cartridge-operated extinguisher. Other RedLine models use different cartridge housing configurations and cover dimensions. Always verify the correct part number for the specific RedLine model being serviced using the ANSUL fire extinguisher parts list — never substitute a cover from a different model even if it appears similar in shape.

What happens if the cartridge cover is missing during operation?

Without the 418025 cover, the cartridge puncturing mechanism and cartridge assembly are exposed to direct mechanical impact from handling, transport, and workplace operations. In industrial environments, an unprotected cartridge assembly can be damaged by forklift strikes, falling objects, or accidental impacts against machinery — potentially impairing the puncturing mechanism's ability to fully initiate agent discharge. A missing cartridge cover is an NFPA 10 inspection deficiency that must be corrected at the time of discovery.
