The Mijing HB21 Pro Aluminum Alloy Oil Injector is a handheld tool for applying small, controlled amounts of lubricant during welding and metalwork.
Designed for routine maintenance and fabrication, it helps operators deliver even oil coverage to contact points, reducing friction and simplifying post-weld cleanup. The rotating head and angled grip support use on awkward joints and confined areas.
-
Material: lightweight aluminum alloy for corrosion resistance and easier handling over long tasks.
-
Rotating design: 360°-style head rotation for access at multiple angles without repositioning the workpiece.
-
Diamond convex grip: textured surface to reduce slippage when hands are oily or gloved.
-
Card buckle attachment: quick-secure fastening for one-handed operation and stable placement on belts or tool trays.
-
Controlled dispensing: metered oil flow to limit waste and achieve uniform coverage on seams and bearings.
Specifications (light): aluminum alloy body; compact handheld form; intended for oil-based lubricants compatible with welding maintenance.
Fit: recommended for welders, fabricators, and maintenance technicians needing precise lubrication in automotive, industrial, or workshop settings.
