Metric Port Plugs with NPT Sensor Port

Convert an M22 x 1.50 fluid port into a dedicated pressure or temperature sensor connection with our aluminium Metric Port Plugs with NPT Sensor Port. The integrated 1/8"-27 NPT female port provides a compact connection for compatible NPT sensors while the M22 x 1.50 connection seals against the component using a supplied O-ring.

Why Choose Our Metric Port Plugs with NPT Sensor Port?

1/8"-27 NPT Sensor Port

Provides a female 1/8"-27 NPT connection for installing compatible pressure and temperature sensors commonly used in automotive and motorsport applications.
M22 x 1.50 O-Ring Connection

The straight M22 x 1.50 male thread secures the plug while the supplied O-ring provides the fluid seal against a compatible mating port.
Compact Sensor Integration

Provides a convenient sensor connection directly from an existing M22 x 1.50 port without requiring an additional adapter assembly.
6061-T6 Aluminium Construction

Precision-machined from lightweight 6061-T6 aluminium and finished with black anodising for protection against wear and corrosion.
Reusable Design

Can be removed and reused provided the threads, sealing surfaces and O-ring remain in good condition.

1/8"-27 NPT Sensor Connection

The integrated female sensor port uses a tapered 1/8"-27 NPT thread. Install a compatible NPT sensor using a suitable thread sealant and follow the sensor manufacturer's installation requirements.

Product Type: Metric Port Plug with NPT Sensor Port Provides a dedicated NPT sensor connection from an M22 x 1.50 fluid port
Material: 6061-T6 Aluminium Lightweight, high-strength alloy
Finish: Black Anodised Protects against wear and corrosion

Connection: M22 x 1.50 Male For installation into a compatible female M22 x 1.50 port
Thread Type: Straight Metric Thread provides retention rather than the fluid seal
Sealing Method: O-Ring Seals against the mating M22 x 1.50 port
O-Ring Included: Yes Supplied with the correctly sized sealing O-ring

Connection: 1/8"-27 NPT Female For a compatible male NPT pressure or temperature sensor
Thread Type: Tapered NPT Thread tightens progressively as the sensor is installed
Sealing Method: Tapered Thread Seal Use a suitable thread sealant when installing the sensor

Apply suitable thread sealant according to the sensor manufacturer's instructions and keep excess sealant clear of the fluid passage.

Available NPT sensor port option
Product Code	Main Port	Sensor Port
PLG-PRT-MET-SEN-NPT-AL-M22X15-18NPT	M22 x 1.50 Male	1/8"-27 NPT Female

Check both connections before ordering. The M22 x 1.50 main port must have a compatible O-ring sealing surface, and the sensor must have a 1/8"-27 NPT male connection.

Frequently Asked Questions

What are metric port plugs with NPT sensor ports used for?
They convert an M22 x 1.50 fluid port into a female 1/8"-27 NPT connection for installing a compatible pressure or temperature sensor.
What size is the sensor port?
The integrated sensor connection is 1/8"-27 NPT Female.
How does the M22 x 1.50 connection seal?
The M22 x 1.50 connection uses a straight metric thread for retention and an O-ring to create the fluid seal against a compatible mating port.
Is the M22 sealing O-ring included?
Yes. The port plug is supplied with the O-ring required for sealing the M22 x 1.50 connection against a compatible port.
How does the 1/8"-27 NPT sensor connection seal?
NPT uses a tapered pipe thread that progressively tightens as the sensor is installed. Use a suitable thread sealant in accordance with the sensor manufacturer's installation requirements.
Does the NPT sensor connection use an O-ring?
No. The 1/8"-27 NPT sensor port seals on its tapered thread rather than using an O-ring. The supplied O-ring is used for the M22 x 1.50 main connection.
Is 1/8" NPT the same as 1/8" BSPP?
No. NPT and BSPP use different thread forms and sealing methods and should not be treated as interchangeable. Check that your sensor has a genuine 1/8"-27 NPT male thread.
Are these port plugs reusable?
Yes. They can be removed and reused provided the threads and sealing surfaces remain undamaged. Inspect the M22 sealing O-ring before reuse and use fresh thread sealant when reinstalling the NPT sensor.
