RectorSeal AC Leak Freeze Pro Nano Refrigerant Leak Sealant — 1.5 oz Magic Frost, Polymer-Free OEM Approved

RectorSeal AC Leak Freeze Pro Nano with Magic Frost is a 1.5 oz refrigerant leak sealant designed to locate and permanently seal small HVAC/R micro leaks using non-polymer nano particles.

This compact professional-grade formula combines leak-seeking nano particles with a triple-action sealant to locate and fill tiny cracks and imperfections in air conditioning and refrigeration coils. Ready to use with a standard 1/4" AC Leak Freeze adapter, the product is OEM approved and intended for installation by trained technicians. It’s polymer-free, non-flammable, and non-toxic, formulated to work safely within HVAC systems to reduce refrigerant loss and restore system efficiency on small leaks.

How does the nano technology find and seal micro leaks?

The Pro Nano formula contains microscopic, non-reactive particles that travel with refrigerant and congregate at leak points, creating a visible frost effect that helps locate the issue. Once concentrated at the leak site, the particles combine with the sealant’s action to fill hairline cracks and imperfections in coils and fittings.

• Nano particles are non-polymer and chemically inert.
• Particles create a visible frost (Magic Frost) at the leak location.
• Particles pack into pores and microfissures to strengthen the seal.
• Works on coils, fittings, and small cracks difficult to detect visually.

Is it safe and easy to apply in HVAC systems?

Yes — the product is supplied in a field-ready 1.5 oz container designed for use with the familiar 1/4" AC Leak Freeze adapter, so experienced HVAC technicians can introduce it into refrigerant lines without special equipment. Being OEM approved, polymer-free, non-flammable, and non-toxic, it’s formulated to minimize compatibility concerns when applied properly.

• Standard 1/4" adapter fits common service ports.
• Ready-to-use dosing reduces on-site preparation time.
• OEM approval indicates manufacturer compatibility when used per instructions.
• Professional installation recommended to ensure system integrity.

What types of leaks and systems does it work on?

AC Leak Freeze Pro Nano is designed for HVAC/R systems in residential and commercial settings, targeting small refrigerant gas leaks and micro-porosity in coils and joints. It’s intended for systems where pinpointing and sealing tiny leaks can restore performance without immediate component replacement.

• Effective on small, slow refrigerant leaks and microfissures.
• Suitable for air conditioning and refrigeration coils and fittings.
• Best for systems compatible with OEM-approved sealants.
• Not a substitute for major repairs or replacement of severely damaged components.

Who should choose RectorSeal AC Leak Freeze Pro Nano? HVAC professionals, service technicians, and contractors who need a compact, field-ready leak sealant for locating and repairing small refrigerant leaks will benefit most. The product is tailored for the tradesman seeking a non-polymer, non-flammable, OEM-approved solution to stop refrigerant loss and help restore system efficiency in homes and commercial buildings. It’s not intended as a do-it-yourself remedy for large failures; professional assessment and installation ensure correct use and long-term system reliability.
