Hi mjD,

Please review the following systems: F-C-1059, F-C-2081 and F-C-2310 if they will work for your penetrations of the Steel pipe and/or PEX pipe. For the water closet, bathtub, and any other conditions we may need to create Engineering Judgment(s) based on our 1 Hour listed systems but for 2 Hours.

Please see the attached EJ request form for your review. We will need the following information inserted into the EJ request form to provide you with an engineering judgment to match your specific field conditions:

1. Job information and contact info
2. Desired F-rating (ex. cold smoke seal or 0hr., 1hr, 2hr….)
3. What type of construction assembly is being penetrated (ex. wall, floor, concrete, gypsum), UL design of construction assembly (ex. U456), or product data sheet of assembly
4. Type of penetration (ex. individual, multiple, PVC, steel), max. diameter or max. size of penetration, Pipe insulation?
5. Min. and max. annular space from the penetration to the periphery of the opening, sleeved opening? What type of sleeve (steel, plastic)?
6. Suggested Hilti products (ex. FS-ONE MAX Firestop Sealant, CFS-BL Firestop Blocks)

Also, please attach any pictures or sketches of your condition for clarity when submitting your request form to usfirestopeng@hilti.com.

After submitting the completed EJ request form, you may want to check on the status of your request. To do so, send your original EJ request form to EJstatus@hilti.com and we will reply back soon with a status update.

Thank You for choosing Hilti as your Firestop Expert!
