NAVAC HVAC Charging Hoses NH5SC — 1/4" SAE 5ft 3-Color Kit with Ball Valves & Replaceable Gaskets

NAVAC NH5SC refrigerant hoses are a three-color, 5-foot set of 1/4" SAE charging lines with ball valves and universal gaskets designed for safe, efficient HVAC refrigerant charging.

If you work on air conditioning or refrigeration systems, having dependable charging hoses speeds service and reduces refrigerant loss. The NAVAC NH5SC kit includes red, blue and yellow 5-foot hoses built for common refrigerants like R410A, R134a and R-22. Each hose uses 1/4" SAE fittings, metal valve handles, and a replaceable universal gasket so you can maintain a tight seal while working under pressure.

How do these hoses prevent refrigerant loss during charging?

The NH5SC hoses include built-in ball valves and quality threaded fittings to isolate lines when you’re connecting or disconnecting equipment. Closing the valve stops flow instantly, so you don’t have to rely on manifold valves alone to control refrigerant. The replaceable universal gaskets ensure a positive seal at the coupling point, minimizing leaks at connection points.

• Ball valves on each hose allow quick shutoff to prevent unintended discharge.
• Replaceable universal gaskets maintain a reliable seal at 1/4" SAE fittings.
• Metal valve handles resist bending under torque compared to plastic alternatives.

What pressure and refrigerant types can the NAVAC NH5SC handle?

These hoses are rated for a working pressure up to 800 psi and a high burst pressure up to 4000 psi, making them suitable for many common HVAC service tasks. They are compatible with refrigerants frequently used in residential and light-commercial systems, including R410A, R134a and R-22, plus other refrigerants within those pressure ranges. Still follow system manufacturer guidelines when servicing high-pressure systems.

• Working pressure: up to 800 psi for normal service operations.
• Burst pressure: tested up to approximately 4000 psi for safety margins.
• Compatible refrigerants: R410A, R134a, R-22 and similar refrigerants.

How is the kit arranged and what makes it easy to use on the job?

The set contains three color-coded 5-foot hoses — red for high side, blue for low side and yellow for service/recovery — helping you avoid crossed connections. One end of each hose has a 45-degree bend to ease access in tight manifolds and valve assemblies. The compact 5-foot length balances reach and control, reducing hose drag while keeping tools close.

• Three-color coding (red/blue/yellow) for clear high/low/service identification.
• 45-degree bent end on fittings for improved access in confined spaces.
• 5-foot length provides a practical balance of reach and manageability during service.

What maintenance and warranty support does NAVAC provide?

NAVAC builds the NH5SC with replaceable gaskets and durable metal valve handles so you can refresh worn parts without replacing the entire hose. Routine inspection of fittings and gaskets before use extends service life. NAVAC backs the product with a one-year warranty to cover manufacturing defects and support reliability on job sites.

• Replaceable universal gaskets make upkeep quick and cost-effective.
• Inspect valves and fittings regularly to avoid service interruptions.
• Includes a 1-year warranty from NAVAC for manufacturing-related issues.

Who is this for: The NAVAC NH5SC set is aimed at HVAC technicians, refrigeration service professionals, and advanced DIYers who need a dependable, portable charging hose kit for common refrigerants. If you value clear color coding, quick valve isolation, and serviceable fittings in a compact 5-foot format, this kit delivers the essentials for routine charging, recovery and diagnostic tasks without unnecessary complexity.
