Hybrilis R134a Enviro-Guard HVAC Hose Set 10ft Red & Blue, Low-Permeation 740 PSI Working

Hybrilis 10-foot Enviro-Guard R134a hose set replaces Robinair lines with low-permeation construction, high-pressure ratings and shop-ready fittings for professional A/C service.

These Hybrilis red and blue hoses are built for refrigerant work on R-134a automotive systems and designed to fit as direct replacements for common Robinair service machines (34788, 34288, 34134Z). They combine a barrier layer to reduce refrigerant loss, durable reinforcement for high-pressure operation, and precise fittings for leak-resistant connections—useful for technicians who need dependable hoses that stand up to daily shop demands.

What makes the Enviro-Guard barrier better for refrigerant work?

The Enviro-Guard barrier layer minimizes permeation of refrigerant gas through the hose wall, lowering product loss and helping maintain system charge during service and storage. It also preserves hose flexibility so lines remain easy to route in tight engine bays.

• Premium barrier material that limits refrigerant permeation.
• Flexible construction for access in confined spaces.
• Visible R-134a markings on both hoses for quick identification.

How safe and durable are these hoses under pressure?

Hybrilis hoses are engineered for heavy-duty, high-pressure use with a working pressure rating of 740 PSI and burst resistance up to 3700 PSI, giving a wide safety margin for typical A/C charging, evacuation and service operations.

• 740 PSI rated working pressure for routine shop tasks.
• 3700 PSI burst pressure for added safety under stress.
• Reinforced layers resist rupture and aging from repeated use.

Are these hoses compatible with my Robinair machine and fittings?

Yes—this set is manufactured to replace Robinair part numbers commonly used on refrigerant service machines; fittings are sized to match standard machine connections for leak-free integration.

• Direct OEM-fit replacement for Robinair 34788, 34288, 34134Z models.
• Includes 14 mm male × 1/2" ACME female fittings for secure connection.
• Deep knurled nuts and six-sided crimped ends ensure durable, hand-friendly installation.

What practical features help mechanics save time in the shop?

The hoses are color-coded, clearly marked for R-134a, and sized at a convenient 10 feet to reach vehicles without tension. Attention to fitting detail and tactile nuts also speed setup and reduce the chance of cross-threading or leaks.

• 10-foot length gives reach without excess slack or strain.
• Red and blue color coding speeds correct hook-up every time.
• Textured nuts allow finger-tightening before final wrench lock, reducing fiddling.

Who is this for: Technicians and shops servicing automotive A/C systems that use R-134a refrigerant and that require reliable, long-lasting replacement hoses compatible with Robinair machines. It suits professionals who prioritize reduced refrigerant loss, high-pressure safety margins, and fast, leak-resistant connections during frequent service cycles.
