HydroLogic® Stealth-RO™ Replacement Inlet Fitting - For Stealth-RO™ Systems

OEM Inlet Fitting for Secure Stealth-RO Water Intake

Every drop that reaches a Stealth-RO system's membrane has to pass through the inlet fitting first, and a worn or leaking one undermines pressure and output before filtration even begins. This genuine OEM inlet fitting restores that entry connection, maintaining the secure, leak-free seal the system depends on for consistent RO performance.

Because it's built to Stealth-RO's exact specifications, it drops in as a direct replacement without modifying the surrounding plumbing or housing.

Key Features & Benefits

• OEM Stealth-RO fit — designed specifically for HydroLogic Stealth-RO systems for guaranteed compatibility.
• Secure connection — maintains a leak-free inlet for reliable water intake and consistent system pressure.
• Durable construction — built to withstand continuous water pressure in RO filtration applications.
• Easy replacement — a straightforward swap that restores system performance without special tools.
• Restores full system integrity — eliminates the entry-point leak or fitment issue that can undermine downstream RO output.

Who Should Use This

Growers running HydroLogic Stealth-RO systems who notice a leak, drop in pressure, or visible damage at the water inlet connection should replace this fitting to restore full system performance before it affects downstream filtration output.

About HydroLogic

HydroLogic has spent roughly two decades building water purification systems for gardening, hydroponic, residential, and commercial use, with the Stealth-RO line built around water-saving reverse osmosis technology. This inlet fitting is one of the OEM service parts that keeps that system sealed and performing at its rated output.

Frequently Asked Questions

How do I know if my inlet fitting needs replacement?

Signs include visible leaks at the inlet connection, reduced water pressure entering the system, or visible cracking or wear on the fitting itself. Any of these point to a fitting that's no longer sealing correctly.

Is this fitting compatible with all Stealth-RO system sizes?

This fitting is designed for HydroLogic Stealth-RO systems specifically; verify your exact system model before ordering, since RO system inlet specifications can vary across product lines. Checking your system's model number against HydroLogic's compatibility documentation before ordering avoids a mismatched fitting.

Do I need tools to replace this inlet fitting?

Most Stealth-RO inlet fitting replacements are a straightforward hand-tightened swap, though checking HydroLogic's specific service instructions for your model before starting is worthwhile. Having a small wrench on hand can still help if the original fitting has become difficult to loosen by hand.

Will a leaking inlet fitting affect my RO system's filtered water output?

Yes, a leaking or poorly sealed inlet reduces the pressure reaching the membrane, which can lower both flow rate and filtration efficiency. Replacing a failing fitting promptly helps keep output consistent.
