Yes, under specific conditions
PEX EVOH Pipe can be used in residential fire sprinkler systems. It is approved for NFPA 13D and NFPA 13R applications. These standards cover residential buildings up to four stories. Example: a single-family home or small apartment building.
NFPA 13D and 13R approval
NFPA 13D covers one- and two-family dwellings. NFPA 13R covers residential occupancies up to four stories. PEX EVOH Pipe is listed for both. Example: a townhouse complex uses approved PEX.
Not approved for commercial NFPA 13
NFPA 13 covers commercial and industrial systems. These have higher hazards and larger areas. PEX EVOH Pipe is generally not approved for these. Example: a large retail store requires metallic pipe.
ASTM F2808 certification requirement
Fire sprinkler pipe must meet ASTM F2808 standards. This covers PEX for fire protection. PEX EVOH Pipe must have this certification. Example: check for ASTM F2808 on the product label.
UL listing and FM approval
UL listing is required for fire protection products. FM Approval may also be needed. PEX EVOH Pipe should have these marks. Example: third-party certification ensures product quality.
Light hazard classification only
PEX is limited to light hazard applications. This includes residences and small offices. Higher hazard areas need metallic pipe. PEX EVOH Pipe is not for high-risk areas.
Example: single-family home system
A new home has a fire sprinkler system. PEX EVOH Pipe is used for the distribution. The system meets NFPA 13D requirements. Example: a safe, effective home fire protection system.
Example: four-story apartment building
A four-story apartment building has a sprinkler system. PEX EVOH Pipe is used for the system. The system meets NFPA 13R requirements. Example: a reliable system for residential buildings.

Example: large commercial building
A large retail store has a fire sprinkler system. PEX EVOH Pipe is not suitable. Steel or copper pipe is required. Example: PEX is not approved for this application.
Local code requirements
Local building codes may have additional requirements. Some areas prohibit PEX for sprinklers. Others accept it with specific conditions. PEX EVOH Pipe must meet local codes.
Temperature and pressure limits
Fire sprinkler systems have specific temperature ratings. PEX must be rated for the system design. Pressure ratings must meet requirements. PEX EVOH Pipe must be rated for sprinkler use.
Final residential use summary
PEX EVOH Pipe is approved for residential fire sprinklers in NFPA 13D and 13R systems. It is not approved for commercial NFPA 13 systems. The pipe must meet ASTM F2808 and be UL listed.
