Is the pressure the same through this slimline tube and a standard tube?

The Slimline Tube is designed to be a smaller lighter and more flexible.

This tube can be used with most CPAP machines.  It is 15mm in diameter and provides a great alternative to standard 6ft tubes. Standard CPAP tubing is usually 19mm in Diameter (interior) with a 22mm rubber cuff which often allows connection to a variety of CPAP machines. For majority of patients the Slimline tube is perfectly fine, is often preferred and will not affect your pressure.
