description

This 343-8799 adapter is machined from high-strength carbon steel with precise internal and external threads and anti-rust passivation treatment. The through oil passage guarantees real-time oil pressure transmission. As a transition fitting, it delivers main oil gallery pressure to the sensor, avoiding interference, thread slipping and oil leakage. It serves as OEM replacement or modification part for excavators, loaders and generator sets, maintaining reliable sealing under continuous hot oil flow.

5. Pressure tested before delivery, stable bearing capacity and less oil leakage alarm

FAQ 

Q：Can 343-8799 work with aftermarket oil pressure sensors?
A：Thread specification must match on both ends. Mismatched threads cause leakage or assembly failure.

Q：Can I use teflon tape to fix oil leakage on the adapter?
A：Not recommended. Replace o-ring first. Teflon debris may clog oil galleries.

Q：What happens if the adapter oil passage is blocked?
A：Distorted pressure signal, abnormal gauge reading and false low oil pressure alarm.

Q：How to store the adapter properly?
A：Protect threads with dust caps, avoid impact and dirt on thread teeth.
