SURIEEN R134A Recharge Hose Kit — 51" Low-Side Charging Hose with Gauge, Brass Fittings & R12 Adapter

SURIEEN R134A Recharge Hose Kit with Gauge is a complete 51-inch low-side charging hose set with a piercing can tap, adjustable quick coupler, and pressure gauge built for service and home recharging of R134A systems.

This kit supplies the parts most DIYers and technicians need to top off or test R134A automotive and small appliance air conditioning systems. Built from brass fittings, a heavy-duty rubber hose, and a clear dial, the set is intended for low-side charging and includes an adapter for older R12 fittings. The design focuses on reliable connections, visible pressure readings, and compatibility with standard R134A service ports.

How does the kit make recharging an R134A system easier?

The kit puts a long, flexible hose and a readable gauge between your refrigerant can and the vehicle's low-side service port, simplifying control and visibility during charging. The adjustable quick coupler snaps on securely and the brass components resist corrosion for repeated use.

• 51" rubber hose provides reach and flexibility for tight engine bays
• Low-side quick coupler with knurled grip for fast connect/disconnect
• Built-in dial gauge shows pressure in common refrigerant scales

Is this a universal tool for R134A, R12, and R22 refrigerants?

The gauge dial includes markings for R134A, R12, and R22 for reference, but the hose is intended to charge one refrigerant at a time. Use the R12 adapter only to adapt fittings—do not mix refrigerants or use the hose across systems without thorough cleaning.

• Includes R12-to-R134A adapter for older fittings, not for mixing refrigerants
• Recommended: dedicate one hose per refrigerant or fully purge before switching
• Dial scales provide pressure guidance but don’t permit combining refrigerants

What are the key safety and durability features?

Materials and pressure ratings are selected for workshop use: solid brass fittings resist wear and the rubber hose withstands typical service pressures. The gauge and fittings are rated to handle common charging conditions, and the piercing can tap is designed to open refrigerant cans reliably.

• Burst pressure rated to 3000 PSI; working pressures up to 500 PSI
• Solid brass connectors for corrosion resistance and long life
• Piercing can tap with 1/2" thread—note: this pierces cans and is not self-sealing

What comes in the box and how do I get support if needed?

The package contains a pair of 51" R134A charging hoses with a low-side adjustable quick coupler on one end and a piercing can tap with 1/2" thread on the other, plus an R12-to-R134A adapter connector. SURIEEN provides customer support if you run into fitment or operation questions.

• Two 51" R134A hoses with gauge integration
• Low-side quick coupler and piercing can tap included
• R12 adapter connector for compatibility with older fittings

Who is this ideal for? The SURIEEN R134A Recharge Hose Kit is best suited for DIY mechanics, mobile technicians, and hobbyists who perform low-side charging, pressure checks, and basic AC maintenance on R134A-equipped cars and small systems. It’s a cost-effective option for anyone who needs a reliable, easy-to-use charging hose with clear pressure readout and standard adapters, but not for applications that require sealed can taps or multi-refrigerant mixing.
