ULTIVATE Inc. Product Lineup

The R555/R556 uses Teflon (PTFE) for the wetted material and rubber flex for the outer material, enabling a significant improvement in durability while achieving displacement absorption. The R555 is suitable for standard spacing, while the R556 is compatible for short spacing, making it ideal for various piping and replacement of existing flex. By using Teflon (PTFE) for the wetted material, the leaching points of impurities are greatly reduced, and the adoption of rubber flex for the outer material eliminates the risk of leakage due to corrosion. **Features** - Wetted material made of Teflon (PTFE) and outer material made of rubber flex - Chemical resistance + vibration resistance + durability + corrosion resistance - Balances composite displacement absorption and strength - Guide bolts for suppressing expansion and contraction displacement can be installed *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.*

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.

What is a flexible joint, to begin with? In simple terms, it is a "soft, stretchable, compressible, and bendable pipe" used for the purpose of "protecting solid objects with its flexibility and supporting smooth movement." 【Where to use flexible joints and expansion joints】 ◆ Moving parts of machinery ◆ Inlets and outlets of rotating equipment such as pumps that experience vibrations ◆ Inlets and outlets of fragile tanks, chemical tanks, and other tanks with leakage risks ◆ Piping that experiences movement due to thermal stress or water hammer The important question regarding flexible joints and expansion joints is: what kind of movement do you want to absorb? The main types of displacement (movement) can be broadly categorized into two: "expansion/contraction" and "eccentricity," with "composite displacement" occurring when both happen simultaneously. You must select the "movement" and the "material" that corresponds to the fluid, but the most crucial point is to choose and manufacture a flexible joint made of a material that matches the usage conditions (pressure, temperature, fluid) and environmental conditions (exposure, burial, outdoor, gas atmosphere). There are numerous considerations in the selection process, and data backed by experience and proven results is essential. Our specialized technical sales staff will be happy to suggest suitable flexible joints, so please feel free to contact us.
