Medical tubing is one of those components that rarely draws attention, yet it is present in almost every clinical setting. From the hose connecting an oxygen cylinder to a patient’s mask to the lines running through hospital gas supply systems, flexible tubing keeps essential substances moving safely where they are needed. This article walks through the fundamentals: what medical tubing is, where it appears in hospitals, which materials are used, what standards govern it, and why properties such as colour coding and antistatic behaviour matter in practice.<\/p>\n
Whether you work in procurement, medical device manufacturing, or hospital facilities management, understanding these basics will help you ask the right questions when specifying or sourcing tubing for healthcare environments.<\/p>\n
Medical tubing is a flexible hose or tube manufactured specifically for use in healthcare and medical device applications. The defining characteristic is not the shape of the product but the requirements it must meet: controlled raw materials, documented compliance with relevant standards, and properties suited to the substances being transferred and the environment in which the tubing operates.<\/p>\n
The term covers a wide range of products. A medical hose might carry a gas such as oxygen or nitrous oxide, channel compressed air within hospital infrastructure, or form part of a piece of diagnostic equipment. What all these products share is that the materials, construction, and performance must be verifiable and consistent. In regulated industries, “we think it should be fine” is not an acceptable basis for specification.<\/p>\n
Medical tubing differs from general industrial tubing in traceability and material control rather than appearance alone. A tube that looks identical to a standard PVC hose may be entirely unsuitable if its raw materials have not been evaluated for the intended medical application.<\/p>\n
Hospitals rely on flexible tubing across a broad range of functions. The common thread is that the tubing must perform reliably, often in environments where failure is not an option. The main application areas include:<\/p>\n
Each of these applications places different demands on the tubing. Reviewing the full range of contexts in which tubing appears in a hospital helps clarify why a single product type rarely covers every need. For a broader overview of how plastic tubing serves healthcare environments, the medical supplies<\/a> sector page provides useful context.<\/p>\n Material selection is one of the most consequential decisions when specifying medical tubing. The material determines chemical compatibility, flexibility, temperature resistance, and whether the tubing meets the regulatory requirements for its intended use.<\/p>\n Medical grade PVC (polyvinyl chloride) is the most widely used material in this category. It is flexible, transparent, cost-effective, and can be formulated to meet medical application requirements. Silicone is another common choice, particularly where high temperature resistance or biocompatibility for direct body contact is needed. TPU (thermoplastic polyurethane) is increasingly specified where chemical resistance and flexibility across a wide temperature range are priorities.<\/p>\n One material consideration that comes up frequently in procurement is phthalate content. DEHP (di(2-ethylhexyl) phthalate) is a plasticiser historically used to make PVC flexible. DEHP-free tubing avoids this substance, which is relevant because DEHP is subject to restrictions under chemical regulations in many markets. Specifying DEHP-free medical grade PVC tubing is now standard practice in many healthcare procurement frameworks.<\/p>\n Material compliance is governed by regulations such as REACH and RoHS<\/a>, which set requirements for the substances permitted in products placed on the European market. When sourcing medical tubing, verifying that raw materials are registered under REACH and that the product meets RoHS requirements is a standard part of due diligence.<\/p>\n Medical gas hoses are subject to specific technical standards that go beyond general material compliance. The most important international standard in this area is EN ISO 5359<\/strong>, which covers low-pressure hose assemblies used for medical gases. It specifies requirements for the hose itself, the end fittings, performance under pressure, and marking.<\/p>\n Compliance with EN ISO 5359 is not a marketing statement but a verifiable technical requirement. Manufacturers must be able to demonstrate that the hose assembly meets the standard’s construction and performance criteria. For procurement teams, asking for documentation of EN ISO 5359 compliance is the correct starting point when sourcing medical gas hose for hospital use.<\/p>\n For a detailed explanation of what EN ISO 5359 covers and which tube materials comply with it, the article on medical gas tubing and EN ISO 5359<\/a> goes into the specifics.<\/p>\n In a hospital gas system, connecting the wrong hose to the wrong gas outlet is a serious safety risk. Colour coding exists precisely to prevent this. Standards assign specific colours to specific gases, so that the tubing colour indicates its intended use at a glance, even under time pressure or in low-visibility conditions.<\/p>\n For example, oxygen lines are typically associated with white, while other medical gases have their own designated colours under the applicable standards. This colour assignment is not decorative. It is a functional safety feature built into the specification of the product.<\/p>\n When sourcing medical gas hose, confirming that the colour matches the standard for the intended gas is as important as confirming the pressure rating. A hose manufactured to the correct colour specification provides an additional layer of protection against misconnection in a clinical environment.<\/p>\n Antistatic tubing is made from materials formulated to prevent the build-up of electrostatic charge on the tube surface. In standard plastic tubing, the movement of gases or particles through the hose can generate static electricity. In most industrial settings this is a minor inconvenience, but in certain hospital environments it becomes a genuine hazard.<\/p>\n Operating theatres and areas where flammable anaesthetic agents or oxygen-enriched atmospheres may be present require materials that do not accumulate static charge. An electrostatic discharge in such an environment could trigger ignition. Antistatic tubing dissipates charge safely rather than allowing it to build to a discharge point.<\/p>\n Specifying antistatic properties is therefore not about performance optimisation but about risk management. In environments where the consequences of static discharge are severe, antistatic tubing is the correct specification, not an optional upgrade.<\/p>\n Toppi Oy, a Finnish plastic extrusion manufacturer with over 70 years of experience, produces the ToppMedic\u2122<\/a> range of hoses specifically for hospital and medical device applications. The product line was developed in collaboration with leading medical device manufacturers, and the specifications reflect the real demands of clinical environments rather than a generic industrial baseline.<\/p>\n ToppMedic\u2122 hoses are designed for gas transfer in hospital equipment and are manufactured in accordance with EN ISO 5359. The colour of each hose follows the applicable standards for the intended gas, providing the visual safety identification that hospital environments require. The raw materials are registered under REACH and the product meets the RoHS directive (2011\/65\/EU), so procurement teams have the documentation they need for compliance purposes.<\/p>\n The construction is a four-layer cross-braided design with polyester yarn reinforcement, giving the hose the structural integrity to handle a working pressure of 14 bar at 20 \u00b0C. The PVC compound used is medical grade, DEHP-free, antistatic, and food-grade, with a hardness of 85 Shore A. Hoses are supplied in 30 m lengths as standard.<\/p>\n Beyond the core medical gas hose, Toppi also manufactures hoses for oxygen mask applications, hoses for hospital compressed air systems, and food-grade tubing<\/a> for catering and nutrition-related hospital use. This means the full range of hospital tubing applications described earlier in this article can be addressed from a single, documented source.<\/p>\nWhich materials are used in medical tubing?<\/h2>\n
