R-422B Refrigerant Recharge Kit – 28.2 oz with Leak Stop & UV Dye | Premium Grade for R-22 System Top-Offs
Service R-422B (NU-22B) systems in a single pass with this premium recharge kit. It combines R-422B refrigerant with an integrated leak-stop additive and high-visibility UV dye — so technicians can top off charges, seal slow leaks, and trace trouble spots without managing separate products.
Why Choose This Kit
- All-in-One Servicing: Refrigerant, leak stop, and UV dye combined for top-offs, leak sealing, and diagnostics in one use.
- Drop-In Convenience: R-422B works as a direct replacement in many R-22 systems, extending equipment life.
- Fast Leak Detection: UV dye reveals leak points quickly under a UV lamp, cutting service time.
Safety & Compatibility
R-422B is non-flammable and non-toxic (A1), but additized kits should be charged following manufacturer procedures. Confirm equipment compatibility before use. As a fluorinated refrigerant, R-422B is subject to phasedown regulations — verify compliance requirements in your jurisdiction before purchase and use.
