GELRIUNY 1/2" HVAC Vacuum Hose 6 ft — 1/2" ID with 1/4"-to-1/2" SAE Flare Fittings, PTFE‑sealed Brass

The GELRIUNY Upgrade 1/2" HVAC Vacuum Hose is a 6‑foot, high‑flow refrigerant hose with a 1/2" internal diameter and 1/4" SAE to 1/2" female flare fittings built for faster evacuation and reliable seals.

This heavy‑duty vacuum certified hose is designed for HVAC and refrigeration technicians who need quicker recovery, low permeation, and durable connections across common refrigerants like R410A, R134a, R407C, R502, R12 and R22. Built with a multi‑layer rubber construction, PTFE‑sealed brass alloy fittings, and high burst/working pressure ratings, it helps speed up evacuation, minimize leaks and withstand demanding shop or field use.

How does this hose speed up evacuation and recovery?

The larger 1/2" internal diameter increases flow capacity compared with smaller hoses, cutting evacuation and refrigerant recovery time. Reduced restriction also lowers the workload on vacuum pumps and recovery machines.

• 1/2" internal diameter for higher flow rates
• 6 ft length for convenient reach without excessive coiling
• Vacuum‑rated to 20 microns for deep evacuation
• Designed for medium‑temperature refrigerants commonly used in HVAC

Are the fittings and seals reliable for professional use?

Yes — GELRIUNY uses brass alloy connectors with PTFE gaskets and deep‑knurled nuts to create secure, low‑leak connections that are easier to hand‑tighten. The assembly is engineered to resist common field stresses and provide consistent sealing performance.

• 1/4" female flare to 1/2" female flare thread compatibility
• PTFE gaskets for robust chemical resistance and sealing
• Deep‑knurled nuts for quicker tool‑free handling
• Brass alloy construction for corrosion resistance

What pressure and durability specifications does the hose meet?

This refrigerant hose is built to withstand demanding pressure ranges: a 640 psi working pressure with a 3200 psi burst rating, making it suitable for recovery and evacuation tasks where higher pressures may be encountered. Multi‑layer rubber construction reduces permeation and extends service life.

• Working pressure: 640 psi
• Burst pressure: 3200 psi
• Four‑layer construction for low refrigerant permeation
• Durable rubber exterior for abrasion and weather resistance

How easy is it to use and maintain in the field?

The hose is a practical balance of length, flexibility and connector design. Its 6‑foot span keeps work areas manageable while the robust fittings and PTFE seals reduce the need for repeated retightening or replacement, and the hose cleans easily after use.

• 6 ft (1.83 m) length for most service scenarios
• Flexible yet reinforced for routine bending without kinking
• Compatible with common HVAC refrigerants and service tools
• Easy to wipe clean and store on an equipment cart

Who is this for? The GELRIUNY 1/2" HVAC Vacuum Hose is aimed at HVAC technicians, refrigeration service pros, and advanced DIYers who demand faster evacuation, solid sealing and rugged hardware for routine recovery and vacuum pulls. Choose this hose when you need higher flow, low permeation and fittings that withstand heavy use; the product also includes a 3‑year support promise to help with service or warranty questions.
