When monitoring critical fluid-film bearings, oil containment is crucial to protect proximity probes and stop environmental fouling. This seal withstands up to 345 kPa (50 psi) across the silicone grommet from high-pressure to low-pressure boundaries. It is engineered specifically for the outer cable jacket, containing volatile lubricants within the casing while safeguarding external junction setups.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBrand: Bently Nevada\u003c\/li\u003e\n\u003cli\u003eModel: \u003cspan style=\"color: #ff0000;\"\u003e\u003cstrong\u003e43501-01-00-01\u003c\/strong\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003eProduct Type: Low Pressure Mechanical Cable Seal\u003c\/li\u003e\n\u003cli\u003eCabling Accommodation: 1 to 4 standard 95-ohm transducer cables, or 1 to 2 heavy-duty 25mm\/50mm DE cables\u003c\/li\u003e\n\u003cli\u003eDifferential Pressure Rating: 345 kPa (50 psi) maximum continuous differential\u003c\/li\u003e\n\u003cli\u003eAbsolute Pressure Minimum: Rated down to 1.0 psi absolute vacuum boundary\u003c\/li\u003e\n\u003cli\u003eAssembled Length: 35mm (1.4 inches) when torqued down to nominal specifications\u003c\/li\u003e\n\u003cli\u003eSealing Media: High-grade molded silicone rubber grommet with compression washer\u003c\/li\u003e\n\u003cli\u003eThread Selection Options: 1\/2-14 NPT and 3\/4-14 NPT global fitting standards\u003c\/li\u003e\n\u003cli\u003eCountry of Origin: United States of America (USA)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cstrong\u003eConfiguration Breakdown\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eThe specific model structure of the \u003cspan style=\"color: #ff0000;\"\u003e\u003cstrong\u003e43501-01-00-01\u003c\/strong\u003e\u003c\/span\u003e is defined by the following hardware selection matrix:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e43501\u003c\/strong\u003e - Base Model: Low Pressure Cable Seal Assembly\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e01\u003c\/strong\u003e - High Pressure Side Thread Size: 1\/2-14 NPT thread fitting\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e00\u003c\/strong\u003e - Cable Grommet and Washer: Solid grommet configuration (no pre-punched holes; custom holes must be field-punched)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e01\u003c\/strong\u003e - Low Pressure Side Thread Size: 1\/2-14 NPT thread fitting\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cstrong\u003eDiagnostic Capabilities \u0026amp; Field Verification\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eProvides passive mechanical pressure-retaining isolation, sealing up to 50 psi differential across the housing boundary.\u003c\/li\u003e\n\u003cli\u003eEnables simple visual inspection of the outer cable jacket for compression tracking and alignment during maintenance reviews.\u003c\/li\u003e\n\u003cli\u003eEnsures continuous containment of lubrication sprays to stop oil tracking along the external instrumentation conduit.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cstrong\u003eTarget Equipment \u0026amp; Application Scenarios\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eCentrifugal compressor housings utilizing 3300 XL 5mm, 8mm, or 11mm proximity probe systems.\u003c\/li\u003e\n\u003cli\u003eSteam turbine fluid-film bearing pedestals requiring multi-cable exit routes through a single tapped casing port.\u003c\/li\u003e\n\u003cli\u003eLarge industrial electric motor end-shields tracking shaft vibration, thrust position, and dynamic expansion.\u003c\/li\u003e\n\u003cli\u003eHigh-speed reduction gearboxes operating with active internal oil splash zones and pressurized spray bars.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cstrong\u003eSelection Comparison \u0026amp; Technical Recommendations\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eWhen engineering instrumentation paths, selecting the right suffix variant dictates deployment success.
