A SoClean sanitizer only works if it can actually connect to your CPAP hose — and that connection depends entirely on one small piece: the injection fitting. If yours has cracked, gone missing, or simply worn out from repeated use, your sanitizer can't do its job at all, no matter how new the machine itself is.
The SoClean Injection Fitting (PN1106) is the exact connector piece that links your SoClean sanitizing unit to your CPAP tubing during a cleaning cycle. Every new SoClean ships with one included — this listing is specifically for replacing that original fitting once it's lost, cracked, or damaged.
It's a tiny part, but it's not optional. Without a working injection fitting, ozone or activated oxygen from your SoClean unit has no sealed pathway into your CPAP hose and mask — meaning your equipment isn't actually getting sanitized during the cycle, even though the machine appears to be running normally.
This fitting is compatible with all SoClean models, including the SoClean 2, SoClean 2 Go, and SoClean 3, so you don't need to hunt for a model-specific version — one part covers the full lineup.
At a low cost and small enough to keep as a spare, replacing this fitting is far cheaper than troubleshooting a sanitizer that seems to be malfunctioning when the real issue is just a worn connector. Many long-term SoClean owners keep a spare on hand specifically because it's an easy part to lose or damage during regular use.
This listing includes the fitting only — it does not include the SoClean sanitizing machine itself, which is sold separately.
A missing or damaged fitting means your SoClean can't properly connect to your hose — this part restores that connection so cycles work as intended.
Rather than assuming your sanitizer is broken and replacing the whole unit, this $7 fix often solves the real problem.
No need to match a specific SoClean generation — this fitting works across the full model range.
Keeping a spare means a lost or cracked fitting doesn't interrupt your cleaning routine while you wait for a replacement to ship.
