[Proposal for Polyethylene Access Holes] We believe everyone is facing difficulties... “To contractors planning to use rigid PVC pipes with a diameter of 600mm” Due to the impact of the Middle East conflict on the supply of domestic PVC products, we hope that our polyethylene access holes, EP-Sleeve, can be of some assistance... * We have stock available only for the 600mm size within Tokyo. * Of course, we also offer cutting services.

A new innovative product for the underground beam sleeve construction is about to be released! Introducing the upgraded version of the "Pipe-in-Sleeve" that you have come to love! "Pipe-in-Sleeve T-type," abbreviated as PIS-T. The T-type features a "water drainage PVC flange" welded with the same material (PVC) to the outer layer of the conventional PIS PVC sleeve. This method serves as an alternative to the ring-shaped or band-shaped water-stopping material on the outer circumference of the PVC sleeve, responding to the strong requests from construction companies. Achieving both work efficiency and construction quality! Stay tuned for the official launch!

As always, our well-known "Non-drying Polyolefin-based One-component Water Stop Putty TometaroⓇ" and the "Underground Wall Waterproof Sleeve Pipe-in-Sleeve (abbreviated as PIS)," which has been well-received since its launch last year, will be exhibited at the "JECA FAIR 2026 - 74th Electrical Equipment Industry Exhibition" held at Tokyo Big Sight. This exhibition is the largest comprehensive electrical equipment exhibition in Japan, showcasing new products related to electrical equipment, tools, measuring instruments, software, systems, and more, as well as introducing construction techniques, improving construction efficiency, academic presentations, and initiatives for reforming work styles in the electrical equipment industry. The exhibition will be at the booth of Furukawa Electric Co., Ltd. We sincerely look forward to your visit.

Proposals for flood prevention and waterproofing construction in general, starting with the familiar water-stopping putty Tome Taro! From cable penetration points to waterproof sleeves for underground exterior walls, and all the way to completely waterproof and odor-proof manhole covers, we solve the "water issues" of underground facilities all at once! ■ [NETIS] Non-drying polyolefin-based one-component water-stopping putty Tome Taro® ■ Waterproof sleeve for underground exterior walls - Pipe-in-sleeve ■ Water pressure-resistant waterproof manhole cover (manhole lid) and machine hatch *For detailed information on each product, please refer to the individual catalogs.

Polyethylene Human Passage (Human Passage Opening) EP-Sleeve ■ High Pressure Resistance: Due to its smooth double structure with a corrugated inner surface, it is strong against impacts and external pressure, possessing excellent flat strength. ■ Lightweight Material: Compared to rigid PVC pipes, it is lightweight. It enhances transportation and work efficiency, contributing to "labor-saving" at construction sites. ■ Rust Resistant: Made of high-density polyethylene, it is safe and secure for installation in water areas! ■ Cold and Chemical Resistant: Compared to rigid PVC pipes, it is suitable for installation in extremely cold regions and shows no deterioration against most chemicals. The polyethylene sleeve "accelerates the 'efficiency' of the site with its 'lightweight'!" A material that combines high pressure strength with "lightweight," which leads to direct construction usability. In particular, while rigid PVC pipes weigh about 53 kg/m, the polyethylene sleeve weighs about 17 kg/m, showcasing an overwhelming weight difference! We guarantee a definite improvement in work efficiency at construction sites. Furthermore, it also contributes to reducing the burden on workers and lowering accident risks, enhancing safety!
