HydroLogic® Stealth-RO™ Double Ended Wrench - For Standard Filter & Membrane Housings

HydroLogic® Stealth-RO™ Double Ended Wrench - The Right Tool for Every Stealth-RO™ Maintenance Task

The HydroLogic® Stealth-RO™ Double Ended Wrench is the purpose-built maintenance tool for Stealth-RO™ system filter and membrane housing access. With a dual-function design — a large end sized for pre-filter housing removal and a small end sized for membrane housing cap removal — this single wrench handles both of the most common Stealth-RO™ maintenance tasks. No improvising with generic wrenches that may slip or crack housings; the Stealth-RO™ wrench is precision-fitted to the exact housing sizes in your system.

Key Features & Benefits

• Double-ended design: One tool for both major maintenance tasks — large end for pre-filter housing, small end for membrane housing cap — eliminating the need for multiple wrenches.
• Pre-filter housing removal (large end): Sized specifically for Stealth-RO™ pre-filter housing for secure grip and torque without housing damage.
• Membrane housing cap removal (small end): Precisely sized for the membrane housing cap — providing the controlled leverage needed for safe, damage-free removal.
• Durable construction: Built to withstand repeated use across regular filter and membrane replacement cycles in commercial and hobbyist growing environments.
• Essential maintenance tool: Makes filter and membrane changes safer and faster — reduces the risk of housing damage from using ill-fitting substitute tools.

Who Should Use This

Every Stealth-RO™ owner should have this wrench on hand. Filter replacements and membrane changes are routine maintenance tasks — having the right tool eliminates the risk of cracked or stripped housings that turn a simple replacement into an expensive repair.

Compatibility

Designed for use with HydroLogic® Stealth-RO™ standard filter and membrane housings.

Frequently Asked Questions

Can I use a standard plumber's wrench or channel locks instead?

While possible, generic wrenches often slip on the smooth cylindrical housing surfaces and can crack or strip plastic housings. The Stealth-RO™ Double Ended Wrench is precision-fitted to provide the correct grip and torque — protecting your housings during maintenance.

Which end is for the pre-filter housing and which is for the membrane housing?

The large end is for pre-filter housing removal. The small end is for membrane housing cap removal.

How often will I need to use this wrench?

Pre-filter cartridges typically need replacement every 2,000-6,000 gallons depending on filter type, and RO membranes when output or TDS rejection declines. Regular filter maintenance is where this wrench earns its place in your toolkit.

Is this wrench compatible with the Evolution-RO™ system housings?

This wrench is designed specifically for Stealth-RO™ standard filter and membrane housing dimensions. Contact HydroLogic® to confirm compatibility with other system models.
