Elyaspedy 1/2" HVAC Vacuum Hose 6ft — High-Flow 20 Micron Certified, 640 PSI Working Pressure

The Elyaspedy Upgraded 1/2" HVAC Vacuum Hose is a 6-foot, high-flow, vacuum-certified refrigerant line designed for fast evacuation, safe recovery, and durable service on R410a, R134a, R407C and other common refrigerants.

Built for HVAC technicians and serious DIYers, this 1/2-inch internal diameter hose balances speed and reliability. It combines a reinforced multi-layer construction, brass-alloy fittings with PTFE seals, and high-pressure ratings to move refrigerant and pull vacuums more efficiently than many conventional hoses. The hose is rated to operate at 640 psi working pressure with a 3200 psi burst resistance and meets vacuum certification to 20 microns, making it suitable for many refrigeration and air-conditioning service tasks.

How does this hose speed up evacuation and recovery?

The larger 1/2" internal diameter permits greater flow volume compared to standard smaller-diameter lines, reducing recovery and evacuation times. That improved flow becomes especially valuable on mid- to large-size systems where pulling a deep vacuum quickly saves labor and run time.

• 1/2" internal bore for higher flow rates and faster evacuation
• Vacuum-certified to 20 microns for reliable deep vacuum pulls
• Supports medium-temperature refrigerants including R410A and R134a

What makes the fittings and seal construction reliable?

Fittings are machined from brass alloy and use PTFE gaskets to create a leak-resistant interface. Deep-knurled nuts simplify hand tightening, while the exhaust port and connector geometry are engineered to maintain a consistent seal under pressure and vacuum cycling.

• Brass-alloy connectors for corrosion resistance and durability
• PTFE gaskets at interfaces for low-leak sealing performance
• Knurled nuts for faster, tool-friendly installation

Is this hose safe for high-pressure work and repeated use?

Yes — the hose is specified for a 640 psi working pressure and a 3200 psi burst pressure, giving a broad safety margin for routine service. Its multi-layer construction reduces permeation and extends service life when used with common refrigerants.

• 4-layer construction lowers refrigerant permeation into the atmosphere
• Heavy-duty materials and reinforcement for long-term durability
• Rated for medium-temperature refrigerants and frequent cycling

What size and connections does the hose use for compatibility?

The hose arrives at 1.83 meters (6 feet) long with a 1/4" female flare to 3/8" female flare adapter configuration, covering typical technician needs for recovery, charging, and vacuuming. That length and thread pairing are intended for easy use on residential and light-commercial systems.

• 6-foot length for maneuverability at service sites
• 1/4" female flare to 3/8" female flare thread sizes included
• Designed for air conditioners, refrigerators, car A/C, and cold storage
