Sure Flow Oxygen Tubing

When a patient depends on supplemental oxygen, the connection between the concentrator or regulator and the cannula has to stay open and reliable — no kinking, no flow interruptions, no compromises. The Sure Flow line from Allied Healthcare delivers exactly that: clear, durable PVC oxygen tubing built for consistent delivery in hospitals, long-term care, and home settings alike.

The Allied Healthcare Sure Flow Oxygen Tubing (64232) is a 25-foot, non-sterile clear tube with a 6.3 mm inner diameter. Its signature feature is the star lumen inner channel paired with a smooth outer wall — a design that resists collapse and flattening when the tubing bends around a bed rail, corner, or wheelchair. That means oxygen keeps flowing at the prescribed rate even when the line is under a chair leg or looped through a doorway, a common frustration with cheaper crush-prone tubing.

The 25-foot length gives patients room to move between a stationary concentrator and daily activities without dragging the machine along, while the clear PVC lets caregivers spot moisture, blockages, or disconnections at a glance. It's a standard-connection tube, so it pairs with the nasal cannulas, regulators, and concentrators you already use.

Buyers stocking oxygen delivery supplies often compare tubing options by lumen design and length. If you're weighing flow performance across product lines, it's worth looking at our Hi-Flow and Precision Flow Rate Tubing collections alongside Sure Flow to match the right tubing to your patients' flow requirements and mobility needs.
