Infinity Replacement Nut

Infinity Replacement Nut (Locking Cap)

The Vital Component for Fitting Maintenance and Repair

Keep your system running and your fittings functional with the Infinity Replacement Nut. Designed as a direct replacement for the outer locking cap found on all standard Infinity Aluminum Piping push-to-connect fittings (20mm – 63mm), this component ensures you never have to discard a complete fitting just because a nut was lost or damaged during installation.

Whether you are refurbishing older lines or simply need a spare part for your maintenance kit, this nut is the exact original equipment manufacturer (OEM) part, guaranteeing perfect thread engagement and secure retention of the internal collet system.

Key Features & Benefits

• Genuine OEM Replacement: Manufactured to the exact tolerances of the original Infinity fittings. It ensures the internal stainless steel grab ring and seal are compressed correctly, maintaining the system’s leak-free integrity.
• Cost-Saving Repair: Accidents happen on the job site. If a nut is cross-threaded, dropped, or lost, this replacement part saves you the cost of buying an entire new Elbow, Tee, or Union.
• Durable Construction: Made from heavy-duty Nickel-Plated Brass, offering the same superior corrosion resistance and strength as the rest of the Infinity metal fitting line. It will not crack or become brittle like plastic caps.
• System Identification: Often used to swap out colored caps (if applicable in specific series) or simply refresh the look of a fitting that has been exposed to harsh external conditions.

Technical Specifications

• Material: Nickel-Plated Brass
• Compatibility: Fits all standard Infinity Push-to-Connect Fittings (Elbows, Tees, Unions, etc.)
• Pressure Rating: Maintains the fitting’s 232 PSI (16 Bar) rating when properly torqued.
• Available Sizes: 20mm, 25mm, 32mm, 40mm, 50mm, 63mm.

Why Stock Replacement Nuts?

During large installations, nuts can sometimes be separated from the fitting body and misplaced. Having a few replacement nuts in your toolbox ensures that installation never grinds to a halt over a single missing part.

Restore your fittings to factory condition. Use genuine Infinity Replacement Nuts for a secure, professional seal.
