SURIEEN refrigeration charging hose set — color‑coded 9.8" (red/blue/yellow) with brass fittings & quarter‑turn ball valves, 600 p

SURIEEN R134A R410A R22 R12 Refrigeration Charging Hose Set with Ball Valve is a three-piece, 1/4" SAE refrigeration charging hose kit with color-coded manual ball valves engineered for safe, one-handed refrigerant charging and HVAC maintenance.

This charging hose set is built for technicians and DIYers who work on automotive and stationary air conditioning systems that use R134a, R410a, R22, or R12 refrigerants. Each hose combines a robust rubber line, solid brass fittings, and a quarter-turn shut-off ball valve for precise control. The kit is rated for heavy-duty service—tested for reliability and designed to mate with standard SAE 1/4" male and female threads, making it compatible with most manifold gauges and HVAC service ports.

How does this hose set improve control during refrigerant charging?

The integrated manual ball valves give you immediate on/off control with a single quarter-turn motion, reducing refrigerant loss and allowing exact charge adjustments. The 45-degree angled connector minimizes hose strain and eases alignment to ports in tight engine bays or condensers.

• One-handed operation with quarter-turn ball valve handles for quick shut-off.
• 45° angled connector reduces kinking and improves access in confined spaces.
• Color-coded knobs (red, blue, yellow) for quick identification of high, low, and service lines.
• Thick rubber gaskets ensure a tight, durable seal to limit leaks during service.

What compatibility and pressure limits should I expect?

These hoses are manufactured to work with common refrigerants (R134a, R410a, R22, R12) and standard SAE 1/4" threads used across HVAC and automotive systems. Pressure ratings are designed to withstand professional workloads while maintaining user safety.

• Compatible with R134a, R410a, R22, and R12 refrigerants.
• Standard 1/4" SAE male and female thread fittings for broad gauge compatibility.
• 600 psi maximum working pressure and a 3000 psi burst rating for durability.
• 100% tested before shipping to confirm sealing and valve function.

How easy is installation and routine use?

The hoses are 9.8 inches long—long enough to reach common service points without excess slack—and sport threaded fittings that screw directly onto service ports or manifold hoses. The valves attach directly to the hose and can be operated without additional tools, saving time on the job.

• 9.8" hose length balances reach and manageability in tight spaces.
• Screws onto existing charging hoses or gauges for instant use.
• Operable with one hand; ideal when you need a second hand free for gauges or tools.
• Manual shut-off simplifies refrigerant control during topping, evacuation, or leak testing.

What materials and build features enhance longevity?

Durable rubber hoses paired with solid brass ball valves resist wear, ozone, and common service stresses. The design emphasizes sealing and reliability so fittings stay tight through repeated connections and disconnections.

• Solid brass manual shut-off ball valves for corrosion resistance and strength.
• Thick internal rubber gaskets for long-term, leak-resistant seals.
• Color-coded valve handles for clear visual identification during repeated use.
• Pre-shipping testing ensures consistent performance out of the box.

Who is this for: The SURIEEN charging hose set suits HVAC technicians, mobile A/C specialists, and competent DIYers maintaining automotive or residential HVAC systems using R134a, R410a, R22, or R12. Choose this kit if you need a compact, service-ready set of hoses with reliable ball valves, standard SAE compatibility, and construction designed for frequent field use. If you require longer reach or alternative thread sizes, consider matching these hoses with the appropriate adapters or extended lines.
