TSI Supercool 39241B-YF Total Leak Stop Plus UV Dye for HFO-1234yf AC Systems (Not for R134a)

Overview

Meet the TSI Supercool Total Leak Stop Plus with UV Dye, designed specifically for HFO-1234yf air conditioning systems. This formula targets small leaks in metal and rubber A/C components, including evaporators, condensers, hoses, gaskets, and O-rings. It is not intended for R134a systems, so verifying refrigerant type is a key first step before use.

In everyday driving scenarios, you may notice a gradual loss of cooling performance or a refill need. This product offers a targeted approach to seal minor leaks while also lubricating the system for smoother operation. It comes with an application hose and a quick-connect coupler to facilitate a safer, more controlled application. The formula is designed to be non-harmful to A/C components, reclamation, or recovery equipment, and it’s compatible with hybrid and electric compressors.

What makes it stand out

• Total Leak Stop formulated for HFO-1234yf systems, sealing small leaks in metal and rubber A/C parts such as evaporators, condensers, hoses, gaskets, and O-rings.
• Compatibility note: confirm your vehicle uses HFO-1234yf; the low-side service port adapter is larger than an R134a port, and the quick-connect hose should fit snugly.
• Each can is overfilled to ensure the right amount of fluid is injected and to account for residual fluid in the hose after application.
• Includes the HFO-1234yf application hose with a quick-connect coupler for easier use and safer connections.
• Scan the QR code on the product box for a short installation video to guide proper usage.
• One can treats one vehicle, offering a convenient, single-vehicle solution for on-the-go fixes.
• Patented “HFC Free” BOV delivery system aims for quick, safe application and controlled delivery.
• Lubrication benefits may support monitoring performance and potentially help extend system life, without altering core refrigerant properties.
• Designed without harmful polymers and safe for hybrid/electric compressors, reclamation, and recovery equipment when used as directed.

Usage and tips

• Verify your vehicle uses HFO-1234yf refrigerant before application; note the port and hose fit require HFO-1234yf compatibility.
• Use the included application hose with the quick-connect coupler; ensure the connection fits snugly before proceeding.
• Shake if recommended, then apply per the QR video guidance to deliver the proper amount of fluid.
• One can is designed to treat one vehicle; follow disposal and safety guidelines after use.
