Elyaspedy 72in HVAC Manifold Hose Set — Vacuum‑Rated 20 Micron, Backflow Prevention, Brass Fittings

The Elyaspedy 2026 Upgrade 22985 Plus II is a 72-inch, vacuum-rated manifold hose set built for HVAC refrigerant service with backflow prevention and wide refrigerant compatibility.

This professional-grade manifold hose set pairs a long 1.83 m (72") reach with durable brass-alloy fittings, PTFE-sealed interfaces and a four-layer low-permeation hose body. Designed for technicians who recover refrigerant, pull vacuum and service a variety of systems, it supports common refrigerants such as R410a, R134a, R407C, R502, R12 and R22. The set’s backflow prevention design and vacuum certification to 20 microns make it suitable for sensitive service tasks where containment and accuracy matter.

What refrigerants and systems can this hose set work with?

The 22985 Plus II is engineered for broad compatibility across residential, automotive and commercial refrigeration lines. It handles modern and legacy refrigerants, making it a flexible choice for mixed-service shops and field technicians.

• Compatible with R410a, R134a, R407C, R502, R12, R22 and other common refrigerants
• Suitable for air conditioners, refrigerators, car A/C units and cold storage systems
• Useful for both recovery and evacuation operations

How does the backflow prevention and sealing work?

The set uses a backflow prevention feature combined with PTFE-sealed connections to reduce the chance of refrigerant migrating back into the system or escaping to the atmosphere. Brass-alloy fittings with deep-knurled nuts deliver secure, hand-friendly connections that resist leaks during use.

• PTFE gaskets at interfaces for reliable sealing
• Backflow prevention design minimizes cross-contamination and accidental return flow
• Deep-knurled connector nuts improve grip for quick, tight hookups

Is this hose set durable and accurate for vacuum work?

Yes — the hose is vacuum-rated down to 20 microns and built using a four-layer construction to limit permeation and extend service life. The inner 1/4" ID passage and quality materials ensure consistent flow and dependable evacuation during critical recovery or pull-down procedures.

• 1/4-inch internal diameter, 1/4" female flare to 1/4" female flare threads
• Vacuum-certified to 20 microns for precision evacuation
• Four-layer hose design reduces refrigerant loss and increases longevity

What should I expect for ease of use and support?

The 72" length gives extended reach for hard-to-access service points while the ergonomically knurled nuts make connections easier in tight spaces. Elyaspedy backs the product with a three-year warranty and customer support to address setup or performance questions.

• 1.83 m (72") hose length for flexible routing and reach
• High-quality brass alloy fittings plus rubber hose for rugged field use
• 3-year warranty and responsive Elyaspedy customer service

Who is this for: HVAC technicians, A/C mechanics and refrigeration service pros who need a dependable, low-permeation hose set for recovery and vacuum tasks. It’s particularly useful for technicians servicing mixed refrigerant fleets, mobile service vans and cold-storage equipment where long reach, leak resistance and backflow prevention are priorities.
