Starting your chainsaw feeling like an arm workout? A decompression valve makes it way easier! This universal valve fits tons of popular chainsaw brands. It's brand new, unused, and in original packaging – a simple upgrade for easier starts.

The valve has an M10x1.0 thread, which is super common on many 2-stroke gasoline chainsaws. It's designed to release a bit of compression when you're pulling the starter rope, making the engine turn over with less effort. Then it automatically closes once the engine starts running. Smart, right?

It's made by Haishine brand and replaces OEM part number 1128 020 9400. Fits STIHL, HUSQVARNA, PARTNER, MAKITA, WACKER, DOLMAR, and probably other similar chainsaws. The style is traditional, and it comes as a single unit (number in pack: 1). The country of manufacture is unknown, but it's a simple mechanical part that either works or it doesn't. If your old decomp valve is leaking, broken, or missing, this affordable replacement can save you a lot of pull-cord frustration. Your shoulder will thank you!
