Abesco Fire Z240 Pipe Collars consist of a zinc coated factory formed steel shell, which contains heat reactive intumescent material. When exposed to temperatures of approximately 300oF the graphite based intumescent material begins to expand (intumesce) rapidly to form a solid insulating char plug which effectively closes and seals openings where plastic pipes penetrate thru fire-rated walls and floors.
Abesco Fire Z240 Pipe Collars have been around for more than 25 years and were a part of the device revolution (self contained firestopping components), and that the intumescent material has an expansion rate of approximately 28% of its volume with a crush value of approximately 10 to 15 psi (69 kPa to 103 kPa).
|Nominal Pipe Size||2″||3″||4″||6″|
|O/D||3″||4 1/4″||5 1/2″||8 1/4″|
|Height||2 7/16″||2 7/16″||2 7/16″||2 7/16″|
All installations shall be in strict accordance with manufacturers printed instructions. The Firestop device shall be tested in accordance with ASTM E814 (UL1479) and classified by Underwriters Laboratories Inc as a Through-Penetration Firestop Device for up to 2 Hour rating.
All through penetrations shall be sealed with a UL Classified system or device as listed within the current UL Fire Resistance Directory, or have approved shop drawings prior to installation.
Suitability for a particular application should be determined prior to installation.
