Ansul R-102 Vent Plug - 068800

The Ansul 068800 is the OEM vent plug for ANSUL R-102 restaurant fire suppression systems. The vent plug seals unused port openings in the ANSUL R-102 distribution piping network — any distribution pipe port that doesn't have a nozzle installed requires a vent plug to seal that opening and prevent grease, debris, or moisture from entering the piping during the system's standby period between service visits.

Think of the vent plug like a cap for an unused outlet in your piping. If an R-102 system design has distribution pipe branch ports that aren't being used for nozzle placement — for example, if the system was designed with excess capacity or if the kitchen layout changed since installation — those unused ports must be sealed. An unsealed port allows grease-laden air from the kitchen hood to back-flow into the distribution piping over time, potentially contaminating the PRX or AnsulEX wet chemical agent or creating a blockage that prevents the agent from reaching active nozzles during a fire event.

The 068800 vent plug is an OEM ANSUL component sized and threaded for R-102 distribution piping port specifications. Using generic pipe plugs risks thread mismatch or leakage at the piping connection. Available through authorized ANSUL distributors. During every semi-annual NFPA 17A and NFPA 96 inspection, the technician will verify all vent plugs in the distribution piping are present, fully seated, and showing no corrosion or leakage. A missing vent plug is an inspection deficiency that should be corrected at the time of service. Document vent plug condition in the fire suppression system inspection record.

Inspect all 068800 vent plugs at every semi-annual NFPA 17A and NFPA 96 inspection. Verify each plug is present, fully threaded into its port, and shows no corrosion that could compromise the seal. Check for any evidence of grease contamination inside the adjacent piping that might indicate a vent plug has been missing or loose. Replace any vent plug showing corrosion, damage, or poor seating with a new 068800 OEM unit immediately. Never substitute a generic pipe plug — thread mismatch can cause leakage in the distribution piping. Document vent plug condition in the fire suppression system inspection record.

How many vent plugs does a typical R-102 system have?

The number depends entirely on how many unused distribution pipe ports exist in your specific ANSUL R-102 system design. Some systems may have none, others may have several — it depends on the system layout and whether any branch ports were designed with future expansion in mind or if the kitchen layout changed after original installation. Your ANSUL R-102 system as-built drawings will show all pipe port locations and indicate which are active nozzle connections and which require vent plugs.
