Aupoko R134a Valve Core Remover Installer Kit – Red/Blue High & Low Pressure Brass Alloy, Dual-Head Tool

The Aupoko R134A Valve Core Quick Remover Installer Kit is a brass-alloy service valve set that lets you remove and install high- and low-pressure R134a valve cores quickly without evacuating the entire AC refrigerant system.

This compact toolkit provides everything a DIYer or HVAC technician needs to swap valve cores on R134a automotive and light commercial air conditioning systems. It combines color-coded high (red) and low (blue) pressure quick couplers, a dual-head core removal tool, a dual-function core grabber, and a small selection of replacement valve cores. Designed to reduce refrigerant loss and speed routine service, the kit is built from brass alloy with an internal stainless-steel ball valve to isolate the system while you change cores.

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

The Aupoko system uses a threaded remover and built-in stainless-steel ball valve to close off the line before you extract or insert a core. That isolation means you don’t have to fully evacuate refrigerant, only a minimal amount may escape during operation. The dual-head remover and core grabber securely hold the valve core, reducing fumbling and repeated attempts.

• Internal ball valve blocks flow while the core is removed.
• Threaded remover seals tightly to the service port.
• Core grabber secures the core for smooth extraction or insertion.
• Color-coded couplers match high (red) and low (blue) ports for quick identification.

What parts are included and what sizes do they fit?

The kit includes both a high-pressure (red) coupler with a 16 mm inner diameter and a low-pressure (blue) coupler with a 13 mm inner diameter, plus a dual-head core removal tool, a dual-function core grabber, five R134a valve cores and five 5V1 valve cores. These components cover the most common automotive R134a service ports and some light commercial fittings. The set’s compatibility makes it a practical starting point for routine maintenance and roadside repairs.

• Red high-pressure coupler: 16 mm inner diameter.
• Blue low-pressure coupler: 13 mm inner diameter.
• Dual-head removal tool fits multiple valve profiles.
• Ten spare valve cores (5 R134a + 5 5V1) included.

How do you use the remover/installer safely and effectively?

First identify the correct service port and attach the color-matched coupler. Use the threaded remover to engage and close the internal ball valve, then insert the core grabber to extract the old core or push in a new one. Work steadily and wear basic PPE—gloves and eye protection—when handling refrigerant fittings to avoid injury from pressurized gas and sharp edges.

• Match coupler color to the service port before attaching.
• Engage the ball valve to isolate the line before removing the core.
• Use the dual-head tool and grabber for controlled insertion/removal.
• Finish by tightening and leak-checking the replaced core.
