Proline® EZ-Twist™ fuel and oil caps are designed to be compatible with many Stihl chainsaw models that use large flip-style caps. Depending on the model, these caps may be used for either fuel or oil applications, as some equipment uses the same cap design for both.
These caps replace the original Stihl large flip caps and feature an easy “insert and twist” design for simpler operation.
This listing includes the caps shown in the product photos. Please carefully compare your original part with the images provided to ensure proper fitment before purchase
"Bought 2 sets, one for a MS310 and one for a MS311. Both fit perfectly and don’t leak.
Much needed improvement over the factory flip caps.
Bought these because a factory cap broke and left me stranded in the woods without a usable saw.
I switched all my caps to these after that and haven’t looked back." - Customer Wayne
