Tigbear R410A Recharge Kit AC Charging Hose Set 59in — Low-Pressure Gauge 0–550 PSI & Brass Adapters

The Tigbear R410A Recharge Kit is a complete AC charging hose set with a 59" low-pressure hose, 0–550 PSI gauge, R410A swivel adapter and R134A tank adapter for HVAC charging and vacuuming.

This kit bundles durable refrigerant hoses and brass adapters needed to service mini-split and residential air conditioning systems that use R410A, R134A, R22 or older refrigerants. Built with SAE flare fittings, a removable core tank adapter and a low-pressure gauge with a shutoff valve, the Tigbear set aims to make vacuuming and charging lines straightforward for technicians and competent DIYers.

How accurate and sturdy is the gauge and hose assembly?

The included low-pressure gauge reads 0–550 PSI and is paired with a shutoff switch valve for controlled connection to the system. Hoses are 59" long with SAE male/female 1/4" flare threads and constructed from rubber with brass fittings, rated for heavy-duty pressures.

• Gauge range: 0–550 PSI, easy-to-adjust zero if needle isn't at 0 PSI
• Hose length: 59" (150 cm) for flexible reach around condensers and mini-splits
• Working pressure: up to 800 PSI, burst rating: 4000 PSI
• Materials: brass alloy fittings and reinforced rubber hose for durability

Can I use this kit on different refrigerants and systems?

Yes. The Tigbear hoses and adapters are compatible with R410A, R134A, R22 and R12 systems when used with the appropriate adapter connections. The set includes both an R410A swivel adapter and an R134A tank adapter to bridge varying service ports.

• R410A swivel adapter: 1/4" Male SAE to 5/16" Female SAE for mini-split ports
• R134A tank adapter: 1/4" SAE male x 1/2" SAE female with removable core
• Use adapter combinations to adapt hoses to many common service fittings
• Designed as a replacement or supplemental charging set for common home units

How does the R134A tank adapter speed up vacuuming?

The brass R134A tank adapter features a removable valve core that allows quicker evacuation of the charging line and tank. Removing the core increases flow during vacuuming, then the core can be reinstalled for controlled charging.

• Removable valve core lets you rapidly pump down lines
• Reinstall core to restore normal charging control and prevent backflow
• Solid brass body resists wear and provides reliable sealing
• Thread sizes match common tank and service port standards

What installation or setup tips should I know before use?

Before connecting, verify that the gauge needle rests at zero; if not, open the gauge cover and adjust the calibration screw. Tighten SAE flare fittings by hand and finish with a wrench—avoid over-torquing—and always follow safety and refrigerant-handling regulations for your area.

• If needle ≠ 0 PSI, open gauge lid and adjust the internal knob
• Hand-start fittings, then snug with a wrench—do not overtighten
• Use the R410A swivel adapter for 5/16" mini-split ports
• Remove tank adapter core to speed vacuuming, replace for charging

Who is this for: The Tigbear R410A Recharge Kit is aimed at HVAC technicians, maintenance professionals and experienced DIYers who need a reliable, multi-refrigerant charging set for mini-splits and residential AC units. It’s useful for servicing R410A systems while remaining compatible with older refrigerants using the included adapters; not intended for beginners without proper refrigerant certifications or safety procedures.
