Resprionics Performance Tubing is 20% lighter and many times more flexible than standard tubing. It works well with smaller, lightweight masks and is less likely to pull on the mask and disrupt the seal. The ergonomically designed cuff is easier to grasp and remove from the mask or tubing. With a standard 6 foot length cuff diameters and wall thickness, Performance Tubing can be easily substituted for standard tubing. The white color provides quick visual differentiation from standard gray tubing.
