Water temperature sender 1/2″ NPT – GSWT1/2

This analog temperature sender works specifically with Livorsi analog 100-250° F Water Temperature gauges. This sender connects to the engine block with a 1/2″ NPT thread. When installing the sender for your gauge onto the engine, do NOT use any sealant on the threads (i.e. Teflon tape, pipe dope, RTV, etc.). Doing so will prevent the sender from making clean contact with the engine, resulting in either faulty or no gauge operation. The senders have a tapered pipe thread to create a seal preventing leakage. This tapered pipe thread also completes the ground to the engine required for proper gauge operation.
