Two types of tubes based on modified PTFE are available in our lineup. All tubes are extremely resistant to bending fatigue and can be used freely in various processes and scenarios. Custom orders for specific sizes are also possible. *There may be length restrictions for a single lot. Please contact us for more details. 【Features】 ■ Teflon (PTFE) straight and convoluted hoses ■ Liquid contact on the outer surface is possible ■ Visibility + durability + chemical resistance ■ Conductive tubes are also available as an option

The RY series combines fluoropolymer tubes with frequently used flange fittings in plants. It is useful for various applications such as liquid level gauges and drop tubes next to tanks, as well as insertion tubes. Conductive PTFE tubes are also available. By adopting a flare structure (a one-piece structure where the tube is expanded into a circular shape) instead of a two-piece structure that clamps the flange fitting to the tube, we achieve complete integration of the tube and fitting, allowing for use as a pipe with minimal risks of pressure loss or leaching. 【Features】 ■ Teflon (PTFE) straight hose ■ Flanged flare processing ■ Visibility + chemical resistance ■ Conductive tube

Flanged flare processing where the tube and fitting are integrated. Combined with a basic fluoropolymer straight tube. The RY series combines fluoropolymer tubes with frequently used flanged fittings in plants. It is useful for various applications such as level gauges and drip tubes next to tanks, as well as insertion tubes. Conductive PTFE tubes are also available. By adopting a flare structure (a one-piece structure where the tube is expanded circularly) instead of a two-piece structure that clamps the flanged fitting to the tube, we achieve complete integration of the tube and fitting, allowing for use as a pipe with reduced risks of pressure loss and leaching. 【Features】 ■ Teflon (PTFE) straight hose ■ Flanged flare processing ■ Visibility + chemical resistance ■ Conductive tube

High-purity chemicals and hazardous fluids require highly useful conductive fluororesins. We have developed a thick-walled type of fully conductive tube that can be directly inserted into tanks and raw material drums, and is also suitable for vacuum transfer. In the RW30, we have applied lining processing to the joint sections, ensuring that no metal parts come into contact with the fluid, allowing for high-purity transfer to the process. 【Features】 ■ Uses thick conductive fluororesin tubes ■ Visibility + strength + lightweight ■ Significantly reduces the risk of breakage due to resin material ■ Reliable durability through specialized fitting crimping ■ SUS exterior available as an option 【Applications】 We recommend using this for filling lines in processes that dislike charging or static electricity, as well as in food, brewing, beverages, seasonings, pharmaceuticals, cosmetics, chemical products, electronic materials, semiconductors, and ultra-pure water lines. 【Applicable Standards】 Food Sanitation Act

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.

Fully contact liquid PTFE convoluted hose for flange piping. By flaring the joint section, the tube and joint are integrated, ensuring high cleanliness, sealing performance, and pressure resistance. The applicable pressure is mainly below 1.0 MPa, and it features high flexibility focused on usability, with the option of conductive PTFE, making it an attractive design with high freedom. 【Features】 ■ Uses Teflon (PTFE) convoluted hose ■ Chemical resistance + flexibility + durability ■ Calculated pressure resistance performance with SUS blade ■ Concentrated technical expertise to secure effective length and flexibility ■ Conductive PTFE tube also available (RY41) 【Points】 ■ Cleanliness The contact material is made entirely of fluororesin PTFE, minimizing the leaching of impurities to the utmost limit. ■ Flexibility High flexibility is achieved through spiral PTFE (fluororesin, Teflon) and specially developed component structures. 【Applicable Standards】 ■ Food Sanitation Act 【Functions】 ■ Negative pressure suction (optional) ■ Conductivity (optional) ■ Oil resistance ■ Non-stick and odor-resistant 【Applicable Industries】 ■ Food, brewing, beverages, seasonings ■ Apparel, cosmetics, chemical products ■ Electronic materials, semiconductor manufacturing, ultra-pure water

While maximizing the material stability of PFA, we have ensured durability and flexibility with FDA-compliant EPDM for the exterior. It is equipped with cold and heat resistance, chemical resistance, and low elution properties, making it suitable for pumping, negative pressure, and suction applications. The introduction of the fully liquid-contact PFA lined joint type TW51 provides maximum safety for the transfer of even higher purity products. 【Features】 ■ Hybrid hose with EPDM exterior and Teflon (PFA) interior ■ Exterior made of a stronger rubber material ■ Significantly reduced elution risk due to PFA's high-strength C-F bonds ■ Complies with USP Class 6 standards ■ Reliable durability through specialized fitting crimping ■ Usable in various processes 【Applicable Standards】 ■ Food Sanitation Act ■ FDA DMF ■ FDA: 21CFR 177.300 ■ FDA: 21CFR 177.1550 ■ FDA: 21CFR 177.2600 ■ USP: Class 6 【Specifications】 ■ Liquid contact material: PFA ■ Intermediate layer: FDA-compliant EPDM ■ Reinforcement 1: High-strength laminated synthetic fiber ■ Reinforcement 2: SUS wire ■ Exterior material: FDA-compliant EPDM ■ Operating temperature range: -40℃ to 150℃

The exterior is made of non-sticky platinum silicone, while the interior features high smoothness PFA, providing flexibility under various temperature conditions. The most distinctive aspect of the TH50 is its high internal visibility. By combining highly transparent silicone and PFA, it allows for easy observation of fluid conditions. In addition to its usability as a hose, it can also serve the role of a flow sight, making it multi-use. The body reinforcement consists solely of wire, making it particularly suited for low-pressure applications. However, with PFA as the wetted material, it leverages characteristics such as chemical resistance, heat resistance, mirror-like smoothness, and being tasteless and odorless, thus providing value in various scenarios. 【Features】 ■ Adopts a hybrid hose of platinum silicone on the outside and Teflon (PFA) on the inside ■ Significantly reduces elution risk due to the high-strength C-F bond of PFA ■ Complies with USP Class 6 standards ■ Ensured durability through dedicated fitting crimping ■ Usable in various processes 【Main Applicable Industries】 ■ Food, brewing, beverages, seasonings ■ Pharmaceuticals, cosmetics, chemical products ■ Electronic materials, semiconductors, ultra-pure water 【Functions】 ■ Negative pressure suction ■ Visibility ■ Oil resistance ■ Non-stick ■ Odor prevention
