14847-34 Bently Nevada Sealtite Flexible Conduit System

Product Overview

The 14847-34 and 14847-AXX assemblies utilize Sealtite flexible conduit to route delicate transducer cabling securely from machinery probes to local monitor racks. This robust conduit protects vulnerable signal wiring against splashing process fluids, heavy washdowns, and accidental impact from plant equipment. The rugged design features a galvanized steel core encased in an extruded thermoplastic jacket that withstands harsh industrial environments.

Precision-engineered pipe fittings manufactured from high-grade steel include a zinc-plated, chromate finish to prevent oxidation. These integrated terminations ensure seamless compatibility with standard watertight equipment enclosures and vibration monitor housing ports.

Configuration & Suffix Breakdown

Technical Specifications

• Core Construction: Interlocking galvanized steel strip core for high mechanical crush resistance.
• Outer Jacket: Extruded thermoplastic elastomer resistant to oils, hydraulic fluids, and weathering.
• Fitting Specifications: 1/2-14 NPT male threaded pipe fittings with zinc-plated chromate coating.
• Length Constraints: Minimum run of 1 foot (01); maximum continuous run of 99 feet (99).
• Operating Temperature: Designed to maintain flexibility across extreme industrial ambient ranges.
• Shielding Performance: Provides mechanical protection without adding electrical ground loops to signal circuits.

Installation Guidelines

• Verify that the required run matches the 14847-AXX dimensional specification before pulling cables through the core.
• Thread the 1/2-14 NPT fittings smoothly into housing ports without cross-threading the zinc-plated threads.
• Maintain generous bend radii during routing to prevent internal stress on enclosed proximity probe cables.
• Secure intermediate conduit spans using cushioned industrial clamps every 3 to 4 feet to prevent vibration fatigue.

Commissioning & Maintenance

• Pre-Power Inspection: Check that terminal fittings are fully tightened against enclosure O-rings to ensure a watertight seal.
• Periodic Integrity Checks: Inspect the thermoplastic jacket annually for signs of cracking or abrasion from adjacent piping.
• Frictionless Pulling: The smooth internal galvanized core allows technicians to pull extension cables without snagging.

Compatibility & Application Scope

• Engineered specifically for Bently Nevada eddy current proximity transducers and velocity sensor installations.
• Mates directly with weatherproof junction boxes, machine casing fittings, and rack enclosures.
• Suitable for outdoor compressor skids, steam turbine auxiliaries, and pump monitoring stations.

Certifications & Commercial Terms

• Quality Standard: Manufactured under strict industrial compliance guidelines.
• Warranty Terms: Backed by a comprehensive 12-month operational warranty from the date of shipment.
• Express Global Dispatch: Fast, reliable delivery options available via FedEx, UPS, and DHL express shipping services.

Frequently Asked Questions (FAQ)

Q1: How do I specify custom lengths when ordering the 14847-AXX conduit assembly?

A1: Replace the "XX" in the 14847-AXX part number with your required footage from 01 to 99 feet. For example, specify 14847-01 for 1 foot or 14847-15 for a 15-foot custom span.

Q2: Can I pull coaxial probe cables through the Sealtite conduit after the fittings are already attached?

A2: Yes, factory-terminated 14847-34 assemblies feature smooth internal galvanized cores that allow insertion of standard probe connectors if pulled carefully using a fish tape.

Q3: What precautions should I take when installing conduit near high-temperature steam lines?

A3: Keep the Sealtite flexible conduit routed away from uninsulated hot piping exceeding the thermoplastic jacket's thermal rating to prevent surface degradation or jacket stiffening.

Q4: Why does the conduit use NPT threads instead of metric dimensions for industrial monitoring?

A4: Standard 1/2-14 NPT tapered pipe threads match global instrumentation enclosure standards, ensuring a metal-to-metal sealing interface that prevents moisture ingress in heavy washdown zones.

Q5: Buying Guidance: When should an engineer choose a fixed 14847-34 assembly versus a custom 14847-AXX run?

A5: Select the standard 14847-34 (34 feet) for typical balance-of-plant sensor drops where excess length can be neatly coiled. Choose the variable 14847-AXX option when tight spatial constraints demand exact custom cutting to eliminate clutter in compact junction boxes.
