Application-Specific FAQs

• What types of applications specifically require a 4.0-inch case length? This length is ideal for mounting through thick compressor housings, into deep bearing housings, through cooling water jackets, or when using long adapter nuts for installation in non-tapped holes.
• Does the FluidLoc cable require any periodic maintenance or re-sealing? No, the FluidLoc feature is a permanent, molded construction within the cable. It does not require any maintenance, re-tightening, or replacement of seals over its service life.
• How does the connector protector work, and should I remove it after installation? The protector is a threaded metal sleeve that screws onto the connector body. You should remove it only when you are ready to connect the probe to the extension cable, and you can keep it on the extension cable's connector when not in use.
• Is the probe's pressure seal affected by the longer 4.0-inch case? The pressure seal integrity relies on the Viton® O-ring at the probe tip, not the case length. The longer case provides more threading for secure mounting but does not change the sealing performance.
• Can I use this probe in a high-pressure application? The probe is designed to seal differential pressure, but Bently Nevada does not pressure test each unit prior to shipment. For known high-pressure applications, you must contact their custom design department for specific testing and validation.
