STP Super Seal Total Leak Stop for R134a Car Air Conditioning – Kit with Low-Pressure Quick-Connect Fitting

Dual-Action Sealant for Rubber and Metal Without Removing Components

The STP Super Seal Air-Con Stop Leak kit is the definitive, fast, and economical solution for eliminating refrigerant leaks and restoring the seal in your vehicle’s air conditioning system. Its advanced formula circulates mixed with gas and oil; upon contact with oxygen or external moisture at the leak site, it reacts to form a flexible seal that withstands high pressures, without clogging the expansion valve or the compressor.

Strengths & Advantages:

• Complete 2-in-1 Sealing: Restores the elasticity and volume of aged rubber gaskets and O-rings, while sealing microporosity and corrosion cracks on metal parts (condenser, evaporator, receiver, fittings).

• Ready-to-Use Kit with Quick-Connect Fitting: Includes the quick-connect fitting specifically designed for the low-pressure (Low Side) service valve on R134a systems, allowing for easy, clean, and immediate application.

• Safe for the Circuit and Equipment: Formulation free of clogging polymers; does not react with refrigerant or oil in the absence of leaks and does not damage A/C recharge stations during normal maintenance.

• Long-Lasting Results: Permanently seals slow micro-leaks (charge loss over weeks or months), eliminating the need for frequent and costly gas refills.
