Oil Injector

Our oil injector series is available in manual and pneumatic drive options, designed for injecting lubricant oil and coolant into automotive A/C compressors. Both versions offer 1/4 oz (7.5 mL) and 2 oz (60 mL) capacity options, suited to precise small-dose injection and larger-volume maintenance work respectively; the pneumatic version requires less physical effort and offers greater efficiency than the manual version, making it well suited to high-intensity, continuous use in professional repair shops.

The product features a side-mounted low-pressure inlet design, with a backflow prevention device built into the adapter-side port to prevent refrigerant backflow contamination. It can be configured with R134a or R1234yf refrigerant-side ports, or an R410A hose adapter, for broad compatibility across mainstream refrigerant systems, and also supports injection of leak-detection dye and color-change indicators. This series is suited to maintenance and diagnostics on all residential and automotive A/C systems — a practical tool for oil injection and refill work in A/C servicing.
