Chemical resistance + vibration damping + durability + corrosion resistance + composite displacement absorption PTFE × rubber flex
Liquid connection PTFE + outer rubber. A multifunctional flexible hose that achieves high durability and composite displacement absorption. Pump, tank, inlet, outlet, piping, flexible hose.
The 【R555/R556】 uses fluoropolymer (PTFE) for the wetted material and rubber flex for the outer material, enabling a significant improvement in durability while achieving displacement absorption. The 【R555】 can be manufactured to various piping lengths and existing flex sizes with standard spacing, while the 【R556】 is available for special spacing. By adopting full PTFE for the wetted material, the leaching points of impurities are greatly reduced, and the use of rubber flex for the outer material eliminates the risk of leakage due to corrosion. 【Features】 ■ Uses PTFE (fluoropolymer) for the wetted material and rubber flex for the outer material ■ Chemical resistance + vibration resistance + durability + corrosion resistance ■ Balances composite displacement absorption and strength ■ Guide bolts for suppressing expansion displacement can be installed 【Points】 ■ Cleanliness The wetted material is entirely PTFE, minimizing the leaching points of impurities to the extreme. ■ Corrosion resistance By using rubber flex for the flange joints and outer material, we have successfully eliminated the risk of leakage due to corrosion. 【Specifications】 ■ Wetted material: PTFE ■ Outer material: EPDM ■ Main compatible fluids: ultra-pure water, pure chemicals, acidic chemicals, acid wastewater, seawater, etc.
basic information
【Joint Section】 ■Both Loose Flange Type ■Compatible with JIS10K, JIS5K, JIS20K, ANSI, DIN, JWWA, and various other flange standards. ■SS400 + Zn, SUS304, PVC, epoxy coating, Roval coating Other materials and surface treatments are also available. 【Notes】 ● Both ends of the flange are of the loose type. ● If the operating pressure exceeds 1.0 MPa, please select the type with optional guide bolts. ● This product cannot be used in places where pressure fluctuations occur frequently, such as on the discharge side of pressurized or booster water pumps. ● Due to the characteristics of the material, there is a possibility of decreased sealing performance. In such cases, please either retighten or use a gasket. *For more details, please refer to the PDF materials or feel free to contact us. *If you would like to receive the 'Tōkatsu Techno Latest Catalog Vol.1, Vol.2' by mail, please feel free to contact us through the Tōkatsu Techno website.
