Hybrilis R-134a Hose Set 10 ft Red & Blue – Robinair-Compatible, Low-Permeation 740 PSI

Hybrilis 10FT 34722 R-134a Hose Set is a heavy-duty red and blue replacement hose pair engineered for Robinair-compatible HVAC service—10-foot, low-permeation, 740 PSI working pressure, with ACME fittings for reliable refrigerant handling.

This hose set is built to be a direct-fit replacement for Robinair machines (models 34788, 34288 and 34134Z) and to withstand the demands of professional A/C service. With a low-permeation jacket and robust crimped fittings, the pair is intended to reduce leaks, stay flexible in tight engine bays and hold up under repeated shop use. The clear R-134a marking and industry-standard dimensions make it easy to identify and integrate into existing tooling.

How does this hose set reduce refrigerant loss during service?

The Hybrilis hoses use premium high-barrier materials to minimize refrigerant permeation and leakage compared with conventional hoses. Reduced permeation keeps system charge more stable while technicians work and during storage.

• Low-permeation compound to limit refrigerant migration
• Clear R-134a marking for correct refrigerant use
• Secure six-sided crimp design to prevent fitting leaks
• High-quality knurled nuts for faster, tighter hand connections

Will these hoses handle the pressures in automotive A/C work?

Yes. Each hose is rated to a 740 PSI working pressure and a 3700 PSI burst pressure, giving a wide safety margin for typical automotive refrigerant service. The construction is sized for daily shop and field use without sacrificing durability.

• 740 PSI working pressure rating for everyday service
• 3700 PSI burst pressure for robust safety margin
• Heavy-duty wall and reinforcement to resist rupture
• Designed for R-134a systems and standard service conditions

Are these hoses compatible with my Robinair machine and fittings?

These hoses are manufactured as a direct OEM-style replacement for Robinair part numbers 34788, 34288 and 34134Z, and include 14 mm male x 1/2 inch ACME female fittings for a tight, leak-minimizing seal. The 1/4 inch inner diameter matches common R-134a service requirements.

• Direct fit for Robinair 34788, 34288, 34134Z machines
• 14 mm male x 1/2" ACME female fittings included
• 1/4" nominal diameter for standard R-134a lines
• Deep knurled nuts for faster finger-tight connections

How easy are these hoses to use in tight engine bays and on daily jobs?

The hoses retain flexibility even in confined spaces, so technicians can maneuver fittings and gauge sets without fighting stiffness. The 10-foot length gives reach for trucks and passenger vehicles while keeping hoses manageable on the bench.

• Flexible jacket maintains maneuverability in cramped areas
• 10-foot length balances reach with control and storage
• Clear color-coding (red/blue) speeds setup and prevents cross-connection
• Sturdy construction suitable for repeated daily handling

Who is this for: The Hybrilis 10FT 34722 R-134a Hose Set is aimed at professional automotive A/C technicians, refrigeration service shops and DIY mechanics who need a reliable, Robinair-compatible replacement. It's suited for users who prioritize leak resistance, safety margin and quick, dependable connections when servicing R-134a systems.
