ALC penetration section piping assembly board for water heaters "Smooth Sleeve"

ALC penetration section piping assembly board for water heaters "Smooth Sleeve"

With a single core extraction, it is possible to process multiple pipes and cables. No caulking is required, significantly improving construction efficiency.

The "Smooth Sleeve" is a piping assembly plate for water heaters that reduces the labor involved in core drilling and caulking when passing multiple pipes and cables through ALC panels. Core drilling (φ160) is completed in one location, resulting in a neat appearance after installation. The sealing packing adheres closely to various pipes and cables to prevent water intrusion, eliminating the need for caulking and contributing to improved construction efficiency. 【Features】 ■ The penetration processing for multiple pipes and cables such as water, gas, and electricity is completed with a single core drill. ■ Utilizes a highly water-resistant double-structured sealing packing. ■ In the unlikely event that water enters, it drains through the internal drainage path. ■ The guide packing fits into the sleeve hole, making positioning easy. *For more details, please refer to the materials. Feel free to contact us with any inquiries.

Prevent water intrusion! Exterior wall penetration sleeve "Non-combustible inclined sleeve"

Prevent water intrusion! Exterior wall penetration sleeve "Non-combustible inclined sleeve"

Since the product body is inclined, it takes into account the water slope from inside the sleeve to the indoor side! The ease of installation for fixed support and waterproofing treatment has improved!

The "Non-combustible Inclined Sleeve" is an external through sleeve made of high corrosion-resistant galvanized steel plate. It has a square flange, making it easy to install and waterproof, and the inclination of the main body prevents water from entering the indoor side from inside the sleeve. Additionally, it can be used in areas where non-combustibility is required, an important performance requirement for buildings, preventing the spread of fire into the wall structure. We also offer the "Fuji Air Duct M," which is a "fire department approved product" that can be used without issues even in narrow attics. 【Features】 ■ Can be used in areas where non-combustibility is required ■ Prevents the spread of fire into the wall structure ■ Made of high corrosion-resistant galvanized steel plate ■ Excellent corrosion resistance ■ Accurate and easy waterproofing during installation *For more details, please refer to the PDF materials or feel free to contact us.
