Respiratory - Oxygen Aids - Roscoe Medical, 25' Green Supply Tubing kink : Kink Resistant Supply Tubing from Roscoe provides patients with high-quality performance and maximum safety. Designed for use with oxygen and oxygen therapy, the three-channel inner lumen design is kink- and crush-resistant, providing a steady and uninterrupted flow of oxygen for maximum safety. The tubing is green tinted for greater visual contras and improved safety. The 25' of tubing, when uncoiled, lies out straight, minimizing "torque" or pull on cannula and letting users have a little bit of mobility as the tubing tracks with them. This is 1 case of tubing and 25 sets come in each case. Universal connectors at each end come standard. Tubing is crush-resistant, ensuring a safe and uninterrupted flow of oxygen. Also available in clear/transparent. Easy to clean, on a weekly basis place the tubing in a sink of warm, soapy water, rinse well and let air-dry out of direct sunlight.
