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

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

Multiple piping and cable penetration processes can be achieved with a single core drill. 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 of multiple pipes and cables, such as water, gas, and electricity, is completed with a single core drilling. ■ Adopts a highly water-resistant double-structured sealing packing. ■ In the unlikely event that water does enter, 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, consideration is given to 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 exterior through sleeve made of high corrosion-resistant galvanized steel plate. It has a square flange, making it easy to install and waterproof, and the inclined design 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, effectively preventing the spread of fire into the wall structure. We also offer the "Fuji Air Duct M," which is a "fire-fighting approved product" that can be used without issues even in narrow attics. 【Features】 ■ Can be used in areas requiring non-combustibility ■ 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.

Public Works / Through Sleeve Pipe-in-Sleeve (Waterproof Cast Iron Pipe)

Public Works / Through Sleeve Pipe-in-Sleeve (Waterproof Cast Iron Pipe)

Serious and solid "flood prevention measures," "labor-saving," and further "pursuit of safe construction."

In recent years, the intensification of typhoons has led to an increase in flooding damage. During Typhoon No. 19 in 2019, the underground electrical equipment of high-rise residential buildings was inundated, and the long-term suspension of infrastructure became a social issue. In response, the national and local governments' flood prevention guidelines strongly recommend flood prevention measures for power supply equipment as essential items. What is Pipe-in-Sleeve? It is a prefabricated sleeve material that has been waterproofed in the factory using PVC sleeves and E-Flex (FEP). It ensures the sound waterproof performance of buildings, while also streamlining on-site work and contributing to safe construction. [Proposed Applications] * Underground beams / exterior wall penetration (power cable entry) [Proposed Facilities] * Government and municipal facilities * Hospitals and welfare facilities * Transportation infrastructure (railways, airports, highways, etc.) ■ Waterproof Cast Iron Pipe VA Proposal ■ <Implementation Effects> * Stable waterproof performance of buildings * Labor saving (reduction of worker burden) * Shortened construction period ● JECA Fair 2026/Product Competition: Received the Encouragement Award from the Japan Electrical Construction Association (in the name of Furukawa Electric Co., Ltd.) ● *For more details, please feel free to request the catalog directly via email or download it from the "EPJ Corporation" "Ipros Special Site" through the related link.
