A three-piece charging kit for R454b, R32 and R410a systems: the SF5050 Check & Charge-It gauge, a 36-inch charging hose and a 5/16-inch low-side adapter. The gauge reads all three refrigerants, so one tool covers the newer A2L blends and older R410a equipment. The hose has a straight 1/4-inch female flare end and a 45-degree angled end with a valve core depressor, which helps reach angled service ports. It suits technicians and serious DIYers servicing R454b or R410a systems who want a compact analog gauge rather than a full manifold set.

This kit is for checking and charging systems that use R454b refrigerant. It includes a Check & Charge-It gauge, a 36" charging hose and a low-side adapter.
The SF5050 gauge has a 1/4" male flare hose connection. Its JB part number gauge reads R32, R454b and R410a.
The hose has a 1/4" female flare connection on each end. One end is straight. The other end has a slight 45-degree angle and an internal valve core depressor. The straight end does not have a valve core depressor and does not need one.
