Description

MOISTURE INSIDE YOUR SYSTEM IS DESTROYING IT - this is the only product that fixes all three problems at once. Moisture in a refrigerant system mixes with refrigerant to form acid - corroding coils, attacking the compressor, accelerating leaks. If your system has been recharged more than once, moisture is likely the real problem. One inject: ProSeal seals the leak, ProDry neutralizes the moisture, UV dye marks the site.

WORKS WITH R410a, R22, R32, R454B, R134a AND MORE - all residential refrigerants covered. Compatible with every refrigerant and oil in standard residential systems. Not for ammonia or CO2. For systems 1.5-5 tons. The 3-in-1 is the right choice for any system over 10 years old or in a high-humidity region.

NO PUMP-DOWN - inject into a running system in under a minute. Connect to the low-side port. Inject using refrigerant or the high side pressure. Disconnect. All three formulas inject together in one trigger pull. No second application. No vacuum pump. Let the system run 45 minutes. Done.

SAFE FOR TXVs, EXPANSION VALVES, AND ALL OILS - never voided a warranty. Both the sealant and moisture remover are safe for all system components. The dehydrating agent in ProDry converts moisture to synthetic oil - it does not leave residue or void manufacturer warranties.

THE RIGHT CHOICE FOR OLD SYSTEMS AND HIGH-HUMIDITY CLIMATES - original manufacturer since 2014. If your system is pre-2010, has visible corrosion, or is located in the Southeast, Gulf Coast, or Pacific Northwest - moisture contamination is almost certain. Use the 3-in-1, not the standard. Enviro-Safe has made this formula since 2014. Made in the USA.

Three problems. One inject. ProSeal XL4 Ultimate 3-in-1 combines leak sealant, moisture remover, and UV dye in a single direct inject cartridge. Moisture inside your AC system forms acid that corrodes coils and accelerates leaks. The 3-in-1 seals the leak, neutralizes the moisture, and marks the site with UV dye - all in 45 minutes with no tools and no pump-down. For systems running R410a, R22, R32, R454B, R134a - 1.5 to 5 tons. The right choice for any system over 10 years old. Enviro-Safe invented Direct Inject in 2014. Made in the USA.

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 $5 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 ENVIRO-SAFE 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.
