Hipa 12538108660 Primer Bulb for ECHO SRM225 SRM210 GT225 SRM211 SRM230 SRM231 SRM265 GT200 GT210 GT230 PPF210 PB200 PE200 PE225 PE230 String Trimmer Blower Weedeater (15Pcs)

What It Is

This is an aftermarket primer bulb (15-pack) designed to replace the OEM 12538108660 bulb on ECHO and compatible handheld outdoor power equipment. It restores the fuel-priming function on string trimmers, blowers, and hedge trimmers that use a push-bulb primer system.

Fitment & Compatibility

Check your model number – this fits most ECHO SRM, GT, PPF, PB, and PE series units (e.g., SRM225, SRM210, GT225, PB200, PE225, PPF210). Do not rely on brand alone – some ECHO models use a different bulb design (e.g., the newer SRM-2620 uses a different part number). Measure your current bulb – this bulb is roughly 1.5 inches long with a 0.5-inch mounting stem. If your bulb has a different stem length or diameter, it won’t fit. Check the fuel line connection – this bulb uses two barbed nipples; make sure your fuel lines are 3/16″ ID. OEM equivalent – it replaces ECHO part #12538108660, but is not OEM; aftermarket bulbs may feel slightly stiffer.

Key Things to Know

• Installation difficulty – simple: remove the old bulb, push the new one into the grommet, and reconnect the fuel lines. No special tools needed.
• Quality – reviews note these bulbs work reliably, but a few users report the rubber can harden faster than OEM after a season of heavy use. For occasional use, they’re fine.
• 15-pack value – you get 15 bulbs for $9.99 (about $0.67 each). Useful if you maintain multiple machines or want spares, but wasteful if you only need one.
• Common gotcha – the bulb may be slightly smaller in diameter than OEM; if your grommet is worn, the bulb might pop out. Replace the grommet if it’s loose.

Should You Buy It

Buy this if you own multiple compatible ECHO units and want a cheap, bulk supply of primer bulbs for quick swaps. Skip it if you only need one bulb for occasional use – a single OEM bulb may last longer and fit more securely.
