GELRIUNY AC Schrader Valve Core Remover Kit — Brass R134a R1234yf R22 with Ball Valve & Spare Cores

GELRIUNY AC Schrader Valve Core Remover Tool Kit is a compact brass toolset for safely removing and replacing valve cores in R134a, R1234yf and R22 refrigeration service ports.

This complete kit bundles high- and low-pressure Schrader valve drivers, multiple valve stems and spare cores plus O-rings so you can service automotive and small refrigeration systems without venting refrigerant. The components are brass for corrosion resistance and include a controllable ball valve to limit refrigerant loss during core removal. Everything fits into a small case for easy storage and quick access on the bench or in the field.

How does this tool prevent refrigerant loss during service?

The kit uses an integrated ball valve in each remover to isolate the system while you unscrew a Schrader core, letting you work with minimal pressure drop. That design reduces the need to evacuate or recharge the system and improves safety when changing faulty cores.

• Controllable ball valve stops flow before core extraction
• Brass construction ensures a tight seal under pressure
• High- and low-side tools color-coded for quick identification
• Replacement cores included to finish the job immediately

Which vehicle and refrigerant types are supported?

This kit is built to work with common automotive and light commercial service ports using R134a, R1234yf and legacy R22 refrigerants. Included stems and spare cores match the typical Schrader types found on those systems.

• Two valve stems tailored for multiple Schrader sizes
• 6 spare valve cores: 2×R22, 2×R134a, 2×R1234yf
• Compatible with most passenger cars, light trucks and small HVAC units
• Useful for aftermarket and OEM service ports

What’s in the kit and how does it speed up repairs?

The set arrives with high- and low-pressure removers (red and blue), a selection of valve stems, six spare cores and eight O-ring seals so you can replace worn parts on the same visit. Having these items together removes the need to run back to the parts store and cuts downtime.

• High-pressure (red) and low-pressure (blue) valve removers
• 2 valve core stems for flexible fitment
• 6 replaceable valve cores and 8 O-rings for immediate repairs
• Compact, service-ready kit for mobile or shop use

How durable and reliable are the components?

GELRIUNY made the tool bodies from brass to resist corrosion and wear when exposed to refrigerants and service environments. The materials and sealing details are chosen to give consistent performance across repeated core changes.

• Brass construction for long-term corrosion resistance
• O-rings provided to restore a pressure-tight seal
• Color coding minimizes user mistakes and speeds operation
• Spare cores supplied to ensure first-time completion

Who is this for? Technicians, mobile service providers and DIYers who work on automotive air conditioning or small refrigeration systems and need a compact, reliable solution for removing and replacing Schrader valve cores. If you require a portable kit that reduces refrigerant loss, contains the common spare parts on hand and fits R134a, R1234yf and R22 applications, this GELRIUNY toolset is built for that purpose.
