R1234yf Refrigerant Charge Hose Kit with Gauge

Mtsooning R1234yf Refrigerant Charge Hose Kit is a purpose-built charging hose and gauge assembly designed to attach directly to R-1234yf left-hand self-sealing cans for accurate low-side charging and pressure checks.

This kit is engineered specifically for technicians and DIYers who need a reliable way to add R-1234yf refrigerant to automotive or small HVAC systems. It features a left-hand 1/2" ACME self-sealing can tap, a low-side adapter, a color-coded pressure gauge, and a heavy-duty hose built to resist high pressure and frequent use. Because it only fits R-1234yf LH self-sealing cans, it prevents cross-connection with incompatible sealed cans and older refrigerants.

How does this kit ensure correct connections with R-1234yf cans?

The tap uses a left-hand 1/2" ACME thread that matches R-1234yf LH self-sealing cans, so you get a secure, leak-minimizing connection each time. This specific threading prevents accidental use with sealed or other refrigerant can types, reducing the risk of poor seals or hazardous cross-contamination.

• 1/2" ACME left-hand (LH) self-sealing can thread for R-1234yf cans
• Self-sealing design maintains valve integrity when disconnected
• Incompatible with sealed or R-134a cans to avoid mismatches

What components are included and how do they perform under pressure?

The kit combines a robust rubber/metal hose, a low-side adapter, and a 200 PSI color-coded gauge for consistent pressure readings during charging. The materials are selected for high-pressure resistance and repeated use, and the gauge provides an immediate visual reference for low-side system pressure during service.

• Total hose length ~19.69 inches for flexible reach and control
• 200 PSI low-side pressure gauge with color coding for quick reading
• Durable rubber and metal construction resists wear and pressure

How should I use this hose kit for charging or checking an air conditioner?

Attach the 1/2" LH self-sealing tap to an R-1234yf LH can, connect the low-side adapter to the vehicle or appliance service port, and read the gauge while admitting refrigerant slowly. The kit is designed for controlled, low-side charging and pressure verification—follow safe charging practices and the system manufacturer's specifications.

• Securely attach tap to R-1234yf LH self-sealing can before opening
• Connect low-side adapter to service port; monitor the 200 PSI gauge
• Add refrigerant gradually and recheck pressure to avoid overcharge

What limitations or compatibility details should I be aware of?

This hose assembly is purpose-made for R-1234yf left-hand self-sealing cans and will not fit sealed-style cans or older refrigerants like R-134a. Using the wrong can type or attempting to force incompatible connections can lead to leaks or equipment damage, so always confirm can and port types before connecting.

• Not compatible with R-1234yf sealed cans or R-134a sealed cans
• Designed exclusively for left-hand (LH) threaded R-1234yf cans
• Intended for low-side charging and pressure checks only

Who is this for: This Mtsooning kit is ideal for professional auto HVAC technicians, fleet maintenance staff, and informed DIYers who work with R-1234yf systems and need a dependable, purpose-built charging solution. Choose this kit if you require a secure LH self-sealing can tap, a clear low-side gauge, and a rugged hose sized for routine service tasks. If you frequently service systems that use other refrigerants or sealed cans, select a tool matched to those fittings instead.
