Silicone Primer Pump Bulb 19mm / 22mm — Carburetor Fuel Ignition Capsule for Small Engines
硅胶注油球（点火胶囊）19mm / 22mm — 适用于小型发动机化油器
A premium silicone primer pump bulb offered in 19mm and 22mm outer diameters, designed for carburetors on chainsaws, brush cutters, hedge trimmers, lawn mowers and similar small-engine equipment. Compared to standard black rubber bulbs, the silicone compound maintains flexibility across a wider temperature range (–40°C to +180°C), resists swelling from ethanol-blend fuels, and retains its shape under high-cycle use. The translucent silicone body allows partial visual confirmation of fuel purge. Sold per piece; OEM bulk pricing available.
