Key Features & Benefits – Sender adapter 1/8" NPT to M14x1.5 (brass)
The sender adapter 1/8" NPT to M14x1.5 (brass) lets you install a 1/8" NPT threaded sender into an M14x1.5 threaded port. It is typically used for pressure or temperature sender installations where the sensor uses 1/8" NPT while the engine or housing provides an M14x1.5 thread.
The adapter is made from brass and is supplied with a crush washer to help seal the connection at the seating surface.
When is this useful?
It is useful when you need to bridge a 1/8" NPT sender to an M14x1.5 port and you want the seal to be made with a washer-style seating surface.

- Sealing surface: verify the port provides a suitable washer seating face so the crush washer can seal on a flat surface.
- Clearance: check that the adapter and sender body clear nearby components before final tightening.
- Orientation: position the sender so the connector and wiring are not under strain and remain accessible.
- Leak check: inspect the joint at operating temperature and ensure the seating faces are clean.
Before installation, verify thread sizes, the sealing surface and available clearance, then match your setup to the technical specs listed above.
