SURIEEN HVAC Charging Hoses 3-Pack 1/4" SAE with Ball Valves — Red/Blue/Yellow, 45° Angled Connectors, 600 PSI Working

SURIEEN HVAC ball valve charging hoses are a set of three 1/4" SAE refrigerant hoses with manual shut-off ball valves, color-coded fittings, and a 45° angled connector for fast, one-handed HVAC charging and service.

These charging hoses are built for HVAC technicians and DIYers working with common refrigerants (R134a, R410a, R12, R22). Each 7" hose combines a solid brass ball valve, thick rubber gasket sealing, and a 45-degree angled connector to reduce stress on fittings. Rated to 3000 psi burst and 600 psi maximum working pressure, the kit includes red, blue, and yellow valves so you can identify service lines instantly. Every hose is pressure-tested before shipping to ensure reliable operation during charging, recovery, or pressure checks.

How do these hoses fit my existing manifold and gauges?

The SURIEEN hoses use standard 1/4" SAE male and female threads compatible with most HVAC manifolds and gauges. The quarter-turn ball valves allow quick control of refrigerant flow without removing the hose, and the 45° angled connector eases attachment in tight spaces. That makes them suitable for most residential and light-commercial service tools.

• Standard 1/4" SAE male/female threads for broad compatibility
• Quarter-turn ball valve for one-handed open/close control
• 45° angled connector reduces strain on connectors in cramped conditions
• Color-coded knobs (red, blue, yellow) for immediate line identification

Are these hoses durable enough for regular HVAC work?

Yes — the hoses combine a thick rubber outer layer with solid brass ball valves to withstand routine service use. The rubber gasket at the fittings helps maintain a tight seal to reduce leaks and wear over time. Each unit is tested before shipping to ensure it meets the rated pressure tolerances.

• Premium rubber construction resists abrasion and kinking
• Brass ball valve hardware for corrosion resistance and reliable sealing
• Pre-shipment pressure test for quality assurance
• 3000 psi burst / 600 psi maximum working pressure rating

What refrigerants and tasks are these hoses suitable for?

These hoses work with common HVAC refrigerants including R134a, R410a, R12, and R22, making them versatile for charging, recovery, and pressure diagnostics. Their size and fittings are intended for standard system service rather than large industrial rigs. Use them for charging, vacuuming, manifold hookup, and leak testing within their rated pressure limits.

• Compatible with R134a, R410a, R12, R22 refrigerants
• Suited for charging, vacuuming, pressure testing, and recovery
• Not intended for oversized industrial refrigerant systems beyond rated pressures
• Ideal for residential and light-commercial HVAC service work

How easy is installation and day-to-day operation?

Installation is straightforward: thread the 1/4" SAE fittings to your manifold or gauge, and use the quarter-turn valve to control flow. The short 7" length gives good control without excess hose bulk, and the angled connector helps reach ports in confined spaces. Color-coded valve knobs speed setup and reduce the chance of cross-connection errors.

• 7" hose length for compact, manageable connections
• Quarter-turn handles enable fast shut-off and one-handed control
• 45° connectors help access tight service ports easily
• Clear color coding: red (high), blue (low), yellow (service/charging)

Who is this for: Technicians, HVAC contractors, and knowledgeable DIYers needing a compact, reliable set of charging hoses compatible with common refrigerants. The SURIEEN kit suits routine residential and light-commercial service tasks where standard 1/4" SAE fittings, color-coded valves, and a robust build are required. If you require hoses for heavy industrial systems or pressures beyond 600 psi working rating, choose equipment engineered for those specifications instead. SURIEEN backs this kit with 24/7 customer service for setup questions and support.
