Industries, commercial businesses, property owners, and others looking for an R-22 replacement to maintain their air conditioning (AC) systems can turn to NU-22B™ refrigerant. NU-22B™ is compatible with all standard oils, equipment components, and materials used in R-22 systems. It does not require the time-consuming oil change that some other replacement refrigerants require. A retrofit blend that is designed to match R-22 in air conditioning applications. There is a slight reduction in capacity which would result in slightly longer run times. Systems that were previously retrofitted to R-417A can operate with a replacement charge of R-422B. The hydrocarbon component in R-422B helps promote oil return in systems containing mineral oil or alkylbenzene. Although HFC refrigerants won’t mix with these oils, the hydrocarbon component thins the mineral oil and keeps it moving around the loop. More complicated piping arrangements or large hold-up volumes may require the addition of POE.Product Features
- Helps save time and money by minimizing labor and component changes.
- For residential AC systems and applications where oil change is inconvenient and/or complex.
- Cool as effectively as R-22 in most systems.
- The Federal Clean Air Act restricts the sale and use of CFC and HCFC refrigerants to technicians certified by an EPA-approved testing organization. Refrigerant prices are subject to change without notice.

Your dog will thank you.
Color: Dogwood & Fresh Breath, Size: Large
My dogs loves to chew on these. They make a small mess but not as bad as other chews. They are food for keeping teeth clean.

Nice chew toy
Color: Dogwood Mushroom, Size: Medium, Color: Dogwood Mushroom, Size: Medium
Super durable and puppy loves it. It was a bit hard for her at first but now at 5 months it’s one of her favorite things to gnaw on! It is heavy for the size but seems to be great quality and has given many hours of chew time with minimal wear.

Puppy loves these sticks!
Color: Dogwood & Calming, Size: Medium
Dogs love these sticks! Must smell and taste like real wood because it keeps my puppy from bringing real sticks in the house from outside. She is a heavy chewer and these sticks keep her occupied. We are on our 2nd set.
