Description

Total Leak Stop for HFO-1234yf AC Refrigerant systems. Stops small leaks in METAL & RUBBER A/C components including evaporators, condenser, hoses, gaskets & O-rings. (NOT FOR USE IN R134a SYSTEMS)

IMPORTANT: Confirm your vehicle uses HFO-1234yf Refrigerant. HFO-1234yf low side service port adapter is larger in diameter than an R134a low side service port. The quick connect hose coupler should fit snugly. If it does not fit snugly it indicates the system is not an HFO-1234yf Refrigerant System

Each can is overfilled to ensure proper amount of fluid is injected into AC System and allows for residual fluid remaining in hose after application

Common questions about buying open-box and refurbished.

Why buy refurbished or open-box?

Refurbished and open-box products offer the same performance as new at a fraction of the price. You're already saving $6 on this listing. They've been inspected, tested, and are ready to use — the only difference is the price tag. Buying refurbished also reduces electronic waste, extending product life cycles and keeping functional devices out of landfills.

What's the difference between open-box and refurbished?

Open-box products are customer returns that have been inspected and confirmed functional. They may show little to no use — often the item was returned simply because the buyer changed their mind. Refurbished products have been professionally repaired or restored by technicians, tested to meet or exceed manufacturer specifications, and sometimes come with a warranty. Both are a smart alternative to buying new.

Why use OpenBoxFox?

Finding refurbished deals is time-consuming — you'd have to check Amazon Warehouse, Reebelo, Dyson Outlet, and others separately for TSI Supercool products. OpenBoxFox aggregates these listings in one place, so you can compare and find the best deal without the legwork. We update pricing daily so you always see current availability and real savings.

Is it safe to buy refurbished?

Yes. Products listed on OpenBoxFox come from established retailers like Amazon, Reebelo, and Dyson — not unknown third-party sellers. Each retailer has buyer protection policies, return windows, and in some cases warranties. You get the price advantage of used goods with the purchase security of a known retailer.
