Low-pressure suction and discharge hose with a transparent inner layer made of chemically resistant PFA and a thick outer layer made of transparent silicone. Designed for various applications in the pharmaceutical, cosmetic, food, and chemical industries, where, in addition to the highest purity, aseptic conditions, and chemical resistance, observation of medium flow is required. The inner layer is made of perfluoroalkoxy polymer PFA (fluoropolymer with properties similar to Teflon), transparent, mirror-smooth, odorless and tasteless, chemically inert, meeting high hygiene requirements (FDA, USP, European EU). Reinforcement with a stainless steel spiral provides good resistance to vacuum. The thick outer layer made of platinum-cured silicone with a smooth surface features non-stick properties (the hose does not "stick") and a low coefficient of friction. It can be easily cleaned using a mild detergent. The hose design combines the advantages of PFA with the flexibility of silicone and its temperature resistance. The hose has a small minimum bend radius, is flexible and elastic at low and elevated temperatures, resistant to cyclic bending according to ASTM D 2176 and dynamic loads. Standards and hygiene requirements: inner layer: USP Class VI, 3-A Sanitary Standards 18-03 Class I, 10/2011/EU, FDA, ISO 10993-4, -10, -11, non-cytotoxic (ISO 10993 Part 5), ICH Q3D; outer layer: USP Class VI, 3-A Sanitary Standards 18-03 Class I, D.M. 21/03/73, FDA, BfR, European Pharmacopoeia 3.1.9, ISO 10993-4, -10, -11, non-cytotoxic (ISO 10993 Part 5). The hose complies with 1935/2004/EC, 2023/2006/EC (GMP), manufactured in Cleanroom ISO 14644-1 Class 8, free from phthalates, adipates, nitrosamines, animal-derived substances, substances subject to EC 1907/2006 (REACH). Confirmation of resistance and conditions of use requires contact with Tubes International. For confirmation of resistance and conditions of use, please contact Tubes International. Installation: use fittings with a smooth spigot ("tail" for the hose) that do not have sharp or high ribs that could cut or damage the inner PFA layer when tightened. The diameter of the spigot should be precisely matched to the diameter of the hose to ensure sealing. Installation with clamp sleeves or bands (clamps). Inner layer: transparent PFA polymer. Reinforcement: AISI 302 stainless steel spiral. Outer layer: transparent silicone. Working pressure: from 1 bar to 3 bar, depending on the hose diameter. Operating temperature: from -30°C to +150°C.

Pressure hose for the transport of anhydrous ammonia in liquid and gaseous form. Inner layer made of thick antistatic rubber (R≤10⁶ Ω/m). Reinforcement with high-strength cord ensures a high safety factor of 5:1. Outer layer made of antistatic rubber (R≤10⁶ Ω/m) resistant to chemicals, abrasion, ozone, and weather conditions, microperforated. Hose compliant with the requirements of standard EN ISO 5771:2008 for rubber hoses for the transport of anhydrous ammonia. The hose is particularly intended for ammonia in the production processes of nitrogen fertilizers, cleaning agents, and for the synthesis of many chemical compounds. It can also be used in other industrial sectors utilizing anhydrous ammonia, such as industrial refrigeration (refrigerant R717 – ammonia, used in large refrigeration systems; flexible hoses are primarily used for filling installations), metallurgy, and many others. The hose can also be used for ammonia dissolved in water - ammoniacal water, widely used in industries such as wastewater treatment (pH regulator), ion-exchange resin regeneration, rubber and plastics industry, and boiler water treatment. Inner layer: black synthetic rubber. Reinforcement: synthetic cord. Outer layer: black synthetic rubber, microperforated. Working pressure: 25 bar. Operating temperature: from -40°C to +55°C.

High-quality suction and discharge hose designed for the transfer of a wide range of aggressive chemical substances. The hose's broad application, primarily in the chemical industry, is conditioned by the excellent resistance of fluoropolymer FEP to aggressive solvents and concentrated alkalis and acids such as hydrochloric, sulfuric, phosphoric, nitric acids, as well as sodium and potassium hydroxides. The hose can also be used in the food and pharmaceutical industries. It is commonly used in cleanroom environments. The inner layer is made of white tetrafluoroethylene/fluoropropylene copolymer FEP (a thermoplastic fluoropolymer with properties similar to Teflon), mirror-smooth (prevents medium deposition on the walls and is easy to maintain cleanliness), odorless and tasteless, meeting high hygiene standards (FDA, USP Class VI). Intermediate layers made of white synthetic rubber include reinforcement with synthetic cord, a steel wire spiral, and two copper wires for discharging electrostatic charges. The outer layer is made of orange EPDM rubber, resistant to abrasion, ozone, and weather conditions. The hose features excellent chemical resistance and cleanliness of FEP, as well as exceptional temperature resistance. Specifically designed for Cleaning-in-Place (CIP) cleaning methods, including steam sterilization at 150ºC. Standards and requirements: Chemical hoses: EN 12115:2011 (type M). Food industry, contact with food (inner layer): USP Class VI, FDA 21 CFR 177.1550. Confirmation of resistance and application conditions requires contact with Tubes International. Inner layer: white, smooth FEP. Reinforcement: synthetic cord, steel spiral. Outer layer: orange smooth EPDM rubber. Working pressure: 16 bar. Vacuum: 0.9 bar. Operating temperature: from -40°C to +150°C.
