Key Features & Benefits – M12x1.5 to 1/8 NPT sensor adapter
The M12x1.5 to 1/8 NPT sensor adapter is a threaded reducer that converts an M12x1.5 port to accept a 1/8 NPT sensor. It fits setups where the vehicle side is M12x1.5 while the sender uses 1/8 NPT.
A hex outer shape supports wrench tightening, and a sealing washer is included. The 20 mm length helps in tighter packaging where overall stack height and tool access matter.
When is this useful?
It is useful when you want to adapt an existing M12x1.5 measurement port to a 1/8 NPT pressure or temperature sender and seal the joint using a washer-type interface.
Technical specs

- Female thread: 1/8 NPT
- Length: 20 mm
- Included: sealing washer
Selection & installation tips
- Thread identification: confirm the port is M12x1.5 and the sensor is 1/8 NPT.
- Sealing: use the sealing washer and ensure the mating face is clean so it seats evenly.
- Packaging: allow for the 20 mm length and hex wrench clearance at the installation point.
- Orientation: set sensor direction and wiring exit so nothing is preloaded or pulled tight.
- Leak check: after assembly, re-check sealing at operating temperature and inspect the joint area.
Before final installation, compare your port thread, sensor thread, and available space to the specs above, then set sealing and positioning based on those parameters.
