Oil Drain Plug Manufacturer
-- Steady & Reliable Manufacturer --
Product Overview
We manufacture oil drain plugs in carbon steel and stainless steel, covering the metric and unified thread sizes used across passenger car, light truck, motorcycle and general machinery applications, with both standard and magnetic (debris-catching) designs. Thread standards, head style, sealing washer and plating can all be matched to an OEM part number or a buyer's own drawing.
We work with automotive aftermarket brands, distributors and OEM purchasing teams who need a manufacturing partner that can hold thread and sealing-face tolerances consistently across a large production run, with private-label packaging available.
