R134A valve core tool kit for HVAC service

This 12-piece set contains two valve core remover installers for high and low pressure ports, two valve core removers, twenty R134A valve cores, twenty 5V1 valve cores and nine service port caps. It is intended for technicians and DIY users servicing automotive air conditioning systems that use R-134a refrigerant. Compatibility with the vehicle's compressor connector and valve core type must be verified before purchase.

Stainless steel rod and quarter-turn ball valve

The upgraded stainless steel valve rod provides stronger suction to hold cores securely during removal, reducing refrigerant escape. Brass bodies with aluminium alloy valves and a quarter-turn ball valve design ensure zero gas loss when the tool is operated. Red high-pressure and blue low-pressure quick couplers with 16 mm and 13 mm internal diameters allow fast, colour-coded connection to the respective service ports.

Anti-slip grip aids control in tight spaces

The tool handles feature an anti-slip surface that improves grip and control while working around crowded engine bays. This single ergonomic detail determines whether the kit can be used confidently on difficult-to-reach valves without slipping or damaging the port.

Questions about this item

The kit supplies 20 R134A valve cores and 20 5V1 valve cores; replace a core whenever it shows wear or leaks during system evacuation or recharge.

What pressure limit do the red high-pressure and blue low-pressure couplers handle during continuous use?

The red coupler fits 16 mm high-pressure ports and the blue coupler fits 13 mm low-pressure ports; both use a quarter-turn ball valve that seals with zero gas loss.

How much heat or noise does the stainless steel valve rod generate during all-day refrigerant recovery?

The tool is a manual hand-operated set with a brass body and stainless steel rod; it produces no mechanical noise or heat beyond normal handling.
