For Coral, changing oil on their Onga pump was messy. The oil drain on the Honda 5.5 hp engine is sitting on top of a base plate (on a trolley) which makes servicing impractical.
She found us and added an EZ-124 (10mm x 1.25) oil drain valve. Servicing is now much easier and quicker.
For those interested, this Honda GX160/Onga pump is used as a water pump to protect against fire. Hopefully, it doesn't have to get used in that capacity.
We have valves for most stationary engines. Check our size guide or contact us.
