Fisher & Paykel Outlet Seal for SleepStyle and SleepStyle+

Genuine replacement Outlet Seal for the Fisher & Paykel SleepStyle and SleepStyle+ Auto CPAP machines. This small but important seal sits at the water chamber outlet to stop moisture from entering the main body of the device. Replace when damaged, worn, or visibly cracked.

Key Features

• Protects the machine from water ingress — forms a watertight barrier between the humidifier water chamber and the air outlet port, preventing moisture from reaching the internal components of the SleepStyle device
• Maintains correct airflow and humidification — a properly seated outlet seal ensures pressurised air moves cleanly from the humidifier chamber through the breathing tube without bypass leaks that could reduce therapy effectiveness
• Genuine F&P replacement part — manufactured to the original tolerances for a secure, consistent fit in the SleepStyle and SleepStyle+ chassis
• Not made with natural rubber latex — suitable for users with latex sensitivities
• Compatible with SleepStyle and SleepStyle+ only — not suitable for older SleepStyle 600 Series (HC-series) machines

Who Is This For?

The outlet seal is a low-cost part that plays an outsized role in protecting an expensive piece of equipment. If you notice water around the base of the water chamber, gurgling that doesn't resolve with a dry tube, or any visible cracking or deformation of the existing seal, replacing it promptly is the right call — water reaching the internal electronics of a CPAP machine can cause serious and costly damage. Fisher & Paykel recommends replacing the outlet seal whenever damage or wear is observed, or as part of routine maintenance when servicing the humidifier system. The Chamber Seal for SleepStyle and SleepStyle+ is a related part that sits at the water chamber lid — if one seal is showing wear, it is worth inspecting the other at the same time.
