Compression seal fittings and feedthroughs for wastewater and water treatment


Using the soft sealant technology pioneered by Conax, we’ve engineered our fittings to seal securely on the individual insulated leads of bearing temperature sensors. That’s why our customers count on Conax fittings and feedthroughs to help:

  • Ensure early failure detection
  • Prevent unplanned downtime
  • Reduce your maintenance costs
  • Enhance safety

There are many ranges of pressure and vacuum seal fittings and a number of assemblies that are configured for specific applications, including bearing temperature sensorshazardous location rated power feedthroughs and conduit seals.

The five standard soft sealant materials used in Conax seal fittings are Neoprene, Viton, PTFE, Lava and Grafoil. When an element (e.g., probe, sensor, electrode) is inserted into a fitting and the cap is torqued to the recommended setting, the torque on the cap translates an axial force on the follower which compresses or crushes the sealant that is contained within the body, thus creating a seal on the element. Tension in the body acts as a spring to maintain compression. Friction between the sealant and the element restrains the element from moving under pressure or vacuum.

  • Model PL (Power Lead) feedthroughs seal on insulated lead wire for use in transformers, motors, conduit boxes, pressure/vacuum chambers, and as power or instrument feedthroughs. Our soft sealant technology seals against gases or liquids and resists element movement under pressure. Immersion length adjustments and easy element replacement can be accomplished in the field.
  • Bearing sensor wire seals (BSWS) efficiently seal directly onto the insulated leads of an embedded temperature sensor in an oil filled bearing housing to prevent oil migrating along the leads. Originally designed for use with embedment bearing temperature sensors to prevent oil migrating along the sensor leads, they seal on the individual insulated leads exiting an oil-filled bearing house and can be used to seal all types of insulated instrumentation lead wire. These sealing assemblies can be found in pumps, large motors, generators, turbines, compressors and journal bearing pedestals.
  • Miniature bearing sensors (MBS) provide a simple, cost-effective way to monitor bearing temperatures to help avoid catastrophic failure and potential damage to the bearing mountings.
  • HL Fittings for Hazardous Locations that are CSA® certified in the U.S. and Canada with a pressure rating of 500 psig for use in many hazardous locations, including sealing conduit runs in many Class 1 and Class 2 hazardous locations.

RTD and thermocouple assemblies for hazardous locations


Conax Technologies’ CBT Series RTD & Thermocouple Assemblies for Hazardous Locations meet U.S. and Canadian standards (NRTL/C and CSA) for use in hazardous locations as defined by NEC Class 1, Division 1, Groups B, C & D; Class II, Groups E, F & G; and Class III.

    • CBT 100 Series sensor terminal head assemblies are available in all thermocouple calibrations and in RTD assemblies with 100, 200, 500 and 1000 ohm platinum, 10 ohm copper or 120 ohm nickel elements.
    • CBT 200 and CBT 300 assemblies are NEC-compliant replacement probes for use with UL and CSA-approved terminal heads in hazardous locations.
    • CT 600 Series sensor terminal head assemblies are available in all thermocouple calibrations and in RTD assemblies with 100, 200, 500 and 1000 ohm platinum, 10 ohm copper or 120 ohm nickel elements.
