NAVAC Rapid Evacuation Kit NEVK3 – Valve Core Removal, Micron Vacuum Gauge, 1/2" ID Hoses (1/4" & 5/16" VCRT, 3/8"/1/2" Adapters)

This all-in-one kit combines NAVAC’s NVR1 valve core removal tool (works with 1/4" and 5/16" flare fittings), two high-flow NHB hoses, adapters for 3/8" and 1/2" to 1/4" lines, and the NMV1 Micron Vacuum Gauge so HVAC technicians can evacuate systems faster and with fewer tool changes. Every component is built to withstand service conditions for modern refrigerants and to reduce downtime during evacuation and recovery tasks.

How does this kit prevent refrigerant loss when removing valve cores?

The NVR1 valve core removal tool is designed to remove and replace valve cores without venting refrigerant to the atmosphere, minimizing product loss and exposure. Its dual-size capability covers both 1/4" and 5/16" flare fittings so you can tackle more system types with a single tool.

• Valve core removal without system discharge.
• Works with 1/4" and 5/16" flare fittings for broader compatibility.
• Durable construction for high-pressure refrigerants including R410A.

What hose and pressure specs ensure fast, reliable evacuation?

Both NHB1 and NHB2 hoses feature a 1/2" internal diameter to increase flow for quicker evacuation and recovery. They are rated for a 640 psi working pressure and a 3200 psi burst pressure, built with a multi-layer design to limit permeation and maintain durability under service conditions.

• 1/2" ID for higher flow rates and reduced pump time.
• 6-foot length for flexible reach on job sites.
• 4-layer construction to resist permeation and abrasion.
• 640 psi working pressure, 3200 psi burst pressure for safety margin.

How accurate is the NMV1 Micron Vacuum Gauge and why does it matter?

The NMV1 Micron Vacuum Gauge provides micron-level readings so you can confirm deep system evacuation before charging. Accurate micron measurement helps detect moisture and non-condensables without relying solely on pressure readings, improving system performance checks.

• Micron-scale vacuum readings for precision evacuation verification.
• Helps identify trapped moisture and non-condensable gases.
• Compact gauge designed for field use alongside hoses and adapters.

What adapters and connections are included to handle different systems?

The NEVK3 kit includes fittings to adapt common service lines, allowing connection between standard manifold ports, 3/8" lines, and 1/2" lines to the 1/4" service interface. This reduces the need to carry multiple standalone adapters and speeds setup on mixed fleets of equipment.

• 3/8" to 1/4" fitting included for many service valves and manifolds.
• 1/2" to 1/4" fitting to connect larger-diameter evacuation lines.
• Compatibility across a wide range of residential and light commercial systems.

Who this kit is for: NAVAC NEVK3 is built for HVAC technicians, service contractors, and refrigeration professionals who need a compact, dependable evacuation solution that reduces tool swaps and speeds pump-down times. It’s especially useful for technicians who service systems using high-pressure refrigerants like R410A, or anyone wanting reliable micron-level verification paired with heavy-duty evacuation hoses. The kit ships ready-to-use and includes a one-year warranty to support trade use and jobsite durability.
