HydroLogic® Stealth-RO™ Replacement Filter Housing - For Stealth-RO™ Systems

OEM Pre-Filter Housing for Stealth-RO Membrane Protection

A pre-filter cartridge only works as well as the housing sealing it in place, and a cracked or poorly fitted housing lets chlorine, chloramine, and sediment slip past toward the RO membrane it's supposed to protect. This replacement filter housing is engineered to Stealth-RO's exact specifications, restoring correct thread dimensions, housing diameter, and o-ring sealing.

It's designed for straightforward cartridge access using the Stealth-RO Double Ended Wrench (HGC741666), keeping routine filter changes simple across the full service life of the system.

Key Features & Benefits

• OEM fitment for Stealth-RO systems — engineered to exact system specifications for correct thread dimensions, housing diameter, and o-ring groove.
• Protects the RO membrane — a properly sealed housing is the first line of defense against chlorine, chloramine, and sediment reaching the membrane.
• Durable construction — built for repeated filter cartridge changes across the system's full service life.
• Easy cartridge access — designed for straightforward removal and reinstallation using the Stealth-RO Double Ended Wrench (HGC741666).
• Restores pre-filtration integrity — replaces a cracked, leaking, or damaged housing to protect downstream RO performance.

Who Should Use This

Stealth-RO operators dealing with a cracked, leaking, or otherwise damaged filter housing should replace it promptly, since a compromised pre-filter housing bypasses the protection the RO membrane depends on for a long service life.

Frequently Asked Questions

How do I know if my filter housing needs replacing?

Look for visible cracks, a housing that no longer holds a tight seal after tightening, or water leaking around the cartridge during operation. Any of these signal a housing that's no longer protecting the RO membrane properly.

What tool do I need to change the filter cartridge inside this housing?

The Stealth-RO Double Ended Wrench (HGC741666) is designed for straightforward removal and reinstallation of the pre-filter cartridge in this housing. Using the correct wrench avoids over-tightening or damaging the o-ring seal.

Does this housing come with a new o-ring?

OEM replacement housings are engineered with the correct o-ring groove dimensions for a proper seal; check your specific kit's included parts list to confirm whether a fresh o-ring ships with it. If an o-ring isn't included, a standard replacement is inexpensive and widely available from RO system parts suppliers.

How often should I expect to replace this housing versus just the filter cartridge?

The filter cartridge inside is a routine consumable replaced on a regular schedule, while the housing itself is only replaced if it cracks, leaks, or is otherwise damaged. Most operators change cartridges far more often than housings.
