THE NOFIRNO® MULTI-CABLE AND PIPE TRANSIT SEALING SYSTEM
The NOFIRNO® sealing system by Beele Engineering (The Netherlands) is a state-of-the-art solution for sealing multi-cable and multi-pipe penetrations. It is designed for applications requiring the highest levels of fire resistance and tightness. From shipbuilding and offshore platforms to industrial plants, NOFIRNO® guarantees superior safety, a proven service life of over 20 years, and a quick, simple installation process.
KEY ADVANTAGES
- Provides certified fire resistance tested to the most stringent international standards including A-60, Hydrocarbon (HC), and Jet Fire.
- Ensures a safe environment with halogen-free materials and a Zero VOC sealant that release no toxic smoke during a fire.
- Reduces installation costs significantly through the use of split insert sleeves and pre-configured multi-filler sleeve sets.
- Offers a maintenance-free solution featuring materials proven to last over 20 years, even in the harshest environmental conditions.
- It is fully re-transitable, allowing for easy upgrades and future cable or pipe additions without dismantling the entire seal.
- Achieves full compliance by holding major international certifications including MED (Wheelmark), USCG, and Kiwa.
SYSTEM COMPONENTS AND TECHNICAL SPECIFICATIONS
The NOFIRNO® system is a complete solution consisting of three fully compatible components:
1. NOFIRNO® Insert Sleeves
- Function: To separate individual cables/pipes, allowing the sealant to flow around them for optimal adhesion and a perfect seal.
- Design: Longitudinally split for easy wrapping around pre-installed cables.
- Sizes: 29 variants available for cable/pipe diameters from 5 mm to 104 mm, with multiple length options (60, 80, 110, 130, 140, 160, 210 mm).
- Operating Temperature: -50°C to +180°C.

2. NOFIRNO® Filler Sleeves
- Function: To fill remaining empty space in the transit opening, providing spare capacity for the future.
- Design: Non-split sleeves supplied in pre-configured multi-sets of 6, 8, 10, or 12.
- Flexibility: Individual sleeves or smaller sets can be easily separated by hand.
- Operating Temperature: -50°C to +180°C.

3. NOFIRNO® Sealant
- Function: A high-performance, fire-resistant silicone compound applied to both sides of the penetration to form a durable, flexible seal.
- Color: Standard: Red-brown. Optional: Blue, black, white, gray.
