Conax Technologies’ Bearing Sensor Wire Seals seal virtually any sensor lead

Our Bearing Sensor Wire Seals (BSWS) are designed to seal virtually any transducer, sensor or detector elements in a wide range of vacuum or pressure boundaries.

The most common use of these seals is for instrument leads on vibration transducers, proximity probes, pressure sensors, temperature sensors, flow meters, and strain gages. Virtually any sensor lead that passes through a pressure boundary can be sealed using one of our compression seal fitting styles.

Conax Technologies’ BSWS assemblies were originally designed for use with embedded bearing temperature sensors to prevent oil migrating along the sensor leads. They seal on the individual insulated leads exiting an oil-filled bearing house. They may also be used to seal all types of insulated instrumentation lead wire. These sealing assemblies can be found in large motors, generators, turbines, pumps, compressors and journal bearing pedestals.

Construction consists of 303 SST standard bodies, followers with a Viton® sealant. Standard assemblies seal 2-14 wires in a variety of wire gauges.

  • Temperature Range: Ambient to +100? F (+37.8? C)
  • Pressure Range: to 50 PSIG (3.4 bar)


The replaceable sealant enables repeated use of the same fitting. Elements can be easily assembled or replaced in the field. To replace the sealant or elements, simply loosen the cap, replace the necessary items, relubricate and retorque the cap.

Fittings are supplied factory lubricated. If fittings are cleaned prior to assembly or when reused, the fittings should be relubricated to maintain the published torque and pressure ratings.
