GELRIUNY 2026 Upgrade 1/2-Inch HVAC Vacuum Hose — High-Flow, 6 ft, 20 Micron Vacuum, 1/4-1/2 Inch Flare Fittings

Meet GELRIUNY's 2026 Upgrade 1/2-Inch HVAC Vacuum Hose, a versatile tool for professional refrigeration and air conditioning work. With a 1/2 inch internal diameter and a high-flow design, this hose supports a broad range of refrigerants including R410A, R134a, R407C, R502, R12, and R22, making it suitable for air conditioners, refrigerators, car AC systems, and cold storage applications.

The hose combines durability with precision engineering. A brass alloy body paired with rubber construction resists wear, while PTFE gaskets ensure a tight seal at the connectors. Deep-knurled connector nuts make installation quick and confident even in tight spaces. The four-layer construction helps minimize permeation to protect your working environment.

Efficiency and performance go hand in hand. The 1/2 inch ID enables faster evacuation and recovery, and the hose is built to handle demanding pressures—the burst rating reaches 3200 psi and the working pressure up to 640 psi. It’s specifically engineered for medium-temperature refrigerants to deliver reliable operation across common service environments. In field tests, technicians notice smoother connections and fewer top-off sessions.

Designed for real-world use, the 6-foot length provides ample reach for service tasks, while the 1/4-inch female flare to 1/2-inch female flare fittings support a range of manifold connections. The hose is vacuum-rated to 20 microns, enabling a clean pull of vacuum during evacuation and process steps. It’s suited for shop benches and on-site work where mobility matters.

Quality and reliability are reinforced by the 3-year warranty and GELRIUNY's responsive support team. This hose aims to be a dependable partner through busy seasons, with materials chosen for durability and a focus on consistent performance across refrigerant tasks.
