Fire Plugz replace standard, non-fireproof inspection ports, which leave a large flame path and failure point in your passive fire protection (PFP) cladding. Manufactured as a two-part assembly, this product is made from a 304 stainless-steel threaded port and a soft plug, manufactured from E-Glass Mat Insulation and 3M™ Interam™ Endothermic Mat E-5A-4. The soft plug provides additional insulating properties, adding even greater back-up fire protection. This also ensures that the R value of the pipe's insulation is maintained at the installation site. The materials used meet ASTM E84 (UL 723), ASTM E 119 (UL 263), ASTM E 1529 (UL 1709), ASTM E 814 and CAN/ULC-S115 standards.


  • Suitable for use on piping and vessel cladding for passive fire protection (PFP)

  • Provides protection against large hydrocarbon pool fires in accordance with ASTM E 1529 (UL 1709)
