Stens Fuel Cap 125-094 for Echo 13100455830

What It Is

The Stens Fuel Cap 125-094 is a direct replacement fuel cap for Echo-branded handheld outdoor power equipment. It seals the fuel tank to prevent leaks and evaporation while allowing pressure equalization through a built-in vent.

Fitment & Compatibility

• Primary fit: Echo part number 13100455830 (OEM). Also cross-references to Stens 125-094.
• Common machines: Echo string trimmers (SRM-210, SRM-225, SRM-230), leaf blowers (PB-200, PB-210, PB-225), hedge trimmers, and chainsaws with the same cap design.
• What to check before buying:
  • Confirm your Echo model uses a threaded, vented cap (not a push-in or non-vented style).
  • Measure the cap’s outer diameter (approx. 1.2 inches) and thread pitch (fine thread, not coarse).
  • Verify the vent is functional—some older Echo caps use a one-way vent that can clog; this Stens cap has a fresh vent design.
  • Not for Honda, Stihl, Husqvarna, or Toro—threads and vent placement differ.

Key Things to Know

• Quality: Built with a rubber gasket that seals well out of the box; no leaks reported in reviews.
• Installation: Tool-free—just unscrew the old cap and hand-tighten the new one. Do not overtighten (can crack the tank neck).
• Gotcha: The vent is non-serviceable—if it clogs, replace the cap again. Store mower/trimmer with the cap snug but not cranked down.
• Price vs OEM: Stens costs roughly half the price of an Echo-branded cap, with identical fit and function.

Should You Buy It

If your Echo handheld’s original cap leaks, won’t seal, or has a stuck vent, this Stens cap is a reliable, budget-friendly fix. It’s a direct drop-in replacement with no modifications needed, and the 4.5-star rating from 300+ buyers confirms it works across multiple Echo models. Avoid it only if you need a cap for a different brand or a non-threaded tank.
