Engineered with an aluminum alloy body, brass fittings, and a user-friendly hand-turn screw mechanism, the tool works on low-side ports for common refrigerants including R410A, R134A, R22 and R12. It’s intended for service techs, DIY mechanics and HVAC hobbyists who need a controlled, compressor-independent method to top up oil or introduce fluorescent dyes for leak detection and diagnostics.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the injector deliver oil or dye without the compressor running?\u003c\/h3\u003e\n\n\u003cp\u003eThe injector uses a screw-in cartridge and internal check valve to force oil or dye into the system by hand-turn pressure rather than relying on system pressure. Tightening the inner core displaces the cartridge contents in a measured way and the check valve prevents backflow into the canister.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eHand-turn screw mechanism discharges fluid gradually for controlled filling.\u003c\/li\u003e\n  \u003cli\u003eInternal check valve keeps refrigerant from entering the injector.\u003c\/li\u003e\n  \u003cli\u003eInner core vent allows air release before injection for smoother flow.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat refrigerants and oil types is this injector compatible with?\u003c\/h3\u003e\n\n\u003cp\u003eThe Aupoko injector is built to work with a wide range of common automotive and small HVAC refrigerants and oils.

The tool’s hand-turn action and snap-on coupler let a single technician accurately add the needed amount without special pumps.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eThree-part assembly: cartridge, check-valve connector, outer cylinder.\u003c\/li\u003e\n  \u003cli\u003eSnap quick coupler makes one-handed connection to low-side port.\u003c\/li\u003e\n  \u003cli\u003eSimple bleed step reduces air pockets before injecting fluid.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill this injector fit all AC systems and what about adapters?\u003c\/h3\u003e\n\n\u003cp\u003eThe tool fits most vehicle and small HVAC low-side fittings via its 1\/4\" SAE female connector, but some R410A systems use larger 5\/16\" ports. If your equipment requires it, use the compatible CV23p adapter for select 5\/16\" R410A fittings to ensure a secure connection.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eStandard 1\/4\" SAE connector suits the majority of systems.\u003c\/li\u003e\n  \u003cli\u003eUse CV23p adapter for specific 5\/16\" R410A service ports when needed.\u003c\/li\u003e\n  \u003cli\u003eAluminum body and brass connector resist corrosion in service environments.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho this product is for: The Aupoko AC Oil and Dye Injector is aimed at professional technicians, mobile mechanics and experienced DIYers who routinely service automotive or small HVAC systems and need a portable, controlled way to add lubricant or UV dye. It’s useful when a compressor is weak or when diagnosing leaks with fluorescent tracers, and for anyone seeking a durable, easy-to-use hand-fill accessory that reduces mess and speeds routine maintenance. The product is backed by Aupoko’s 12-month warranty and the company offers customer support to help with installation questions or compatibility concerns.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Can I use this injector with R410A systems?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes, it supports R410A, but some R410A ports need a CV23p adapter for 5\/16\" fittings.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Does the tool require the compressor to be running?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: No, the hand-turn screw and check valve let you inject oil or dye without the compressor.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"Aupoko","offers":[{"title":"Default Title","offer_id":48086286860446,"sku":"B07F9K4XGX","price":46.98,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0781\/2041\/9486\/files\/aupoko-front-view-injector.jpg?v=1785893814","url":"https:\/\/northtrailauto.ca\/products\/aupoko-ac-oil-and-dye-injector-2-oz-hand-turn-screw-in-with-1-4-sae-quick-coupler-aluminum-body","provider":"North Trail Auto","version":"1.0","type":"link"}
