When the Sensor Port Isn't in the Kit
Off-the-shelf gauge-adapter kits cover the popular ports — 1/8 NPT, 1/8 BSPT, a handful of metric sizes. The moment your sensor, transducer or instrument uses something outside that set — an OEM-specific port, a fine metric pitch, a mixed combination — the kit runs out and you're stuck. The sensor is right; the adapter to mount it simply isn't sold.
EKINSUN machines that adapter. We make custom sensor thread adapters for pressure, temperature and gauge/transducer ports, in the exact thread on each end, in brass, 316 stainless or steel — single pieces through small batches, quoted in 24 hours.
For pure thread-standard conversion see thread adapters; for clean-bore lab and medical fluidics see precision machined fittings.
Sensor & Instrument Ports We Adapt
Pressure transducers
Mount a transducer to a port it wasn't made for — NPT, BSPT, metric, with the right seal.
Gauges & senders
Oil, fuel and boost gauge ports beyond the universal adapter set.
Temperature probes
Thermowell and probe ports adapted to the fitting your line provides.
Process instruments
Flow, level and analytical sensor ports in 316 for harsh or corrosive media.
Discontinued OEM ports
Obsolete sensor port adapters reproduced from a sample.
Conversions & Seals We Machine
| Port / conversion | How we handle it |
|---|---|
| BSPT ↔ NPT | Common gauge/sender conversion — tapered both sides, but different angle and taper, so we cut a true converting adapter |
| Metric ↔ NPT / BSPP | Fine metric sensor ports (e.g. M10×1.0, M12×1.5) to NPT or BSPP |
| Seal feature per end | Taper for NPT/BSPT, flat or O-ring boss for BSPP/SAE, cone where required — so the sensor seats and seals |
| Material for the media | Brass for mild service; 316 stainless or steel for high pressure, temperature or corrosive media |

Materials for Sensor Adapters
316 stainless
For high pressure, high temperature and corrosive or chemical media — where brass kits fall short.
316 machining →Steel & titanium
Carbon/alloy steel for high pressure; titanium for biocompatibility and aggressive corrosion.
Discuss material →No Drawing? We Reverse Engineer It
Send the adapter or both ports
The old adapter, or the sensor and the line port it must join — even a worn sample.
We measure & draw it
Threads, seal and bore captured; we rebuild the CAD for free. How it works →
Confirm, then machine
You approve the drawing, then we turn and inspect it. Copy from a sample →
What to Send Us
- The sensor and the line port, or the old adapter — or photos with one known dimension
- The thread on each end if you know it (e.g. 1/8 BSPT sensor to 1/8 NPT line)
- Medium, pressure and temperature (so we pick the right material and seal)
- Quantity — one to prove the fit, or a batch — and delivery country
No CAD, no problem. Rebuilding the drawing is our job — free, confirmed with you before anything is cut. See how to order with no CAD file.
Frequently Asked Questions
Yes — exactly what we do. Off-the-shelf kits only cover common ports. When your sensor or instrument port falls outside that set, give us the thread on each end (or a sample) and we machine the adapter that joins your sensor to your line.
Yes — between BSPT, NPT/NPTF, BSPP, UNF and metric sensor ports, male or female, with the correct sealing feature on each end so the sensor seats and seals as designed.
Yes. Many universal kits are brass, which isn't ideal for high pressure, temperature or corrosive media. We machine in 316 stainless or steel for hydraulic, chemical and process use, with the wall thickness and seal to suit the pressure.
Yes. Send the old adapter or the sensor and mating port — even worn — and we measure the threads, bore and seal faces, rebuild the drawing free, then machine a compatible replacement. No drawing or part number needed.
From a single piece or prototype up to small and medium runs. No tooling cost on a machined adapter, so a one-off sensor adapter is welcome.
