What Are Brass Connectors for Flexible Conduits?

Brass flexible conduit connectors are fittings used to terminate flexible metallic or non-metallic conduits to electrical enclosures, junction boxes, motors, and control panels. They provide a secure mechanical grip on the conduit while forming a liquid-tight or EMI-shielded termination. Available in fixed (90°, 45°, straight) and swivel designs, they accommodate installation in tight or constrained spaces. Nickel-plated variants add RoHS-compliant surface protection against marine, chemical, and humid environments.

Types of Brass Flexible Conduit Connectors We Manufacture

1. Fixed Straight Brass Conduit Connectors (Natural & Nickel Plated)

Our standard straight connectors feature a two-part body — a union nut and body — that clamps the conduit braid or jacket firmly. Available in metric and NPT/PG thread entries. Nickel-plated finish provides 200+ hour salt-spray resistance per ASTM B117. Thread sizes: M16 to M63, PG7 to PG48, NPT ½” to 2″.

2. Swivel Brass Conduit Connectors (360° Rotation)

Swivel connectors incorporate a rotating union that allows 360° rotation after installation, eliminating conduit torsion in dynamic or vibrating applications (motors, robotics, CNC machinery). The swivel mechanism uses precision-machined internal bearing surfaces for smooth rotation under load. Available with nickel plating for harsh environments.

3. 90° Angle Fixed Connectors (Elbow Type)

Fixed 90° elbow connectors redirect conduit runs in tight enclosure corners or where panels lack depth clearance. CNC-machined in one piece from CW614N brass for structural integrity. Inside bend radius optimised to prevent conduit kinking. Available in natural and nickel-plated finish.

4. 45° Angle Fixed Connectors

The 45° variant offers an intermediate bend angle suited for diagonal cable runs and angled panel entries. Particularly popular in European-style switchgear and automotive assembly plants. Supplied in metric thread sizes M16–M50 and PG thread range.

5. Nickel-Plated Brass Swivel Connectors (EMI/RFI Shielded)

For applications requiring electromagnetic interference (EMI) or radio-frequency interference (RFI) shielding, our nickel-plated swivel connectors feature a conductive plating that makes 360° electrical contact with the braided conduit shield, providing continuous EMI/RFI protection. Suitable for medical equipment, defence electronics, and telecoms installations.

6. Liquid-Tight Flexible Conduit Connectors (Brass Body)

Liquid-tight connectors feature a sealing ferrule and O-ring system achieving IP65 to IP68 ratings. Suitable for wet locations, food processing plants, outdoor electrical installations, and petrochemical environments. Available in fixed straight, 90° elbow, and swivel configurations.

7. Armoured Cable / SWA Gland Adaptors (Brass)

Transition adaptors that allow flexible conduit termination into armoured cable gland threads. Bridges the gap between flexible conduit systems and SWA (steel wire armoured) cable termination points. CW614N brass body with optional nickel or chrome plating.

8. Locknut & Bushing Sets for Conduit Connectors

Complete sets including brass locknuts, insulating bushings, and sealing rings for a fully compliant conduit termination system. Locknuts machined in CW614N brass with knurled OD for hand-tight installation. Bushings in nylon or brass, rated to 105°C.

Frequently Asked Questions (FAQ)

Q1. What is the difference between a fixed and swivel brass conduit connector?

A fixed connector has a rigid body that does not rotate after installation — the conduit must be aligned correctly during fitting. A swivel connector has an internal rotating joint that allows 360° rotation of the conduit entry even after the connector body is tightened onto the enclosure, making it ideal for dynamic wiring applications, motor connections, and installations where torsional stress on the conduit must be avoided.

Q2. What thread types are available for brass conduit connectors?

We manufacture connectors in all major international thread standards: Metric (M16, M20, M25, M32, M40, M50, M63), PG thread (PG7 through PG48), NPT (½” to 2″) for USA/Canada markets, and BSP (G thread) for UK and Australian markets. Mixed-thread versions (e.g., metric body with NPT panel entry) are available as custom items.

Q3. Is nickel plating on brass connectors RoHS compliant?

Yes. Our electrolytic nickel plating process uses nickel sulphamate or nickel sulphate baths that are free from cadmium, lead, hexavalent chromium, and other RoHS Directive 2011/65/EU restricted substances. All plated connectors are suitable for CE-marked electrical assemblies sold in the European Union and UK market.

Q4. What IP rating can I achieve with brass conduit connectors?

Standard brass conduit connectors achieve IP65 (dust-tight and jet-water resistant) when correctly installed with the sealing ring and locknut torqued to specification. Our liquid-tight series with O-ring seals and compression ferrules achieves IP67 (immersion to 1 metre for 30 minutes) and IP68 (continuous immersion, depth and duration per manufacturer’s specification).

Q5. Which conduit types are compatible with these connectors?

Our brass connectors are compatible with: flexible metallic conduit (FMC), liquid-tight flexible metallic conduit (LFMC), flexible non-metallic conduit (FNC/FNMC), corrugated stainless steel tubing (CSST), and PVC-coated flexible conduit. The correct connector model is selected based on conduit OD, wall construction, and the desired IP rating at the termination point.

Q6. Do you supply metric-to-NPT adapter connectors?

Yes. We manufacture transition connectors with a metric conduit entry on one side and NPT panel entry on the other, and vice versa. These are widely used when European-sourced flexible conduit must terminate into US-standard enclosures (NEC Article 350 panels with NPT knock-outs), or when US conduit must enter metric-threaded European equipment.

Q7. What is the temperature rating of brass conduit connectors?

CW614N brass retains its mechanical properties from -40°C to +120°C continuously. For short-term exposure, brass connectors can withstand up to +150°C. The nylon sealing ring components are rated to 105°C (PA66). For higher-temperature applications, silicone or EPDM seals can be substituted, extending the rating to +150°C continuous.

Q8. Can you produce custom conduit connectors to our drawings?

Absolutely. We regularly produce custom conduit connectors to customer-supplied 2D drawings or 3D CAD files (STEP, IGES, DWG formats accepted). Custom features include: non-standard thread sizes, special OD clamping ranges, reduced-profile bodies for space-constrained enclosures, dual-entry versions, and bespoke plating or passivation treatments. Minimum quantities for custom items are typically 500–1,000 pieces depending on complexity.

Q9. What packaging is available for export shipments?

We offer polybag and inner box packaging (50–100 pieces per box), bulk poly bag packaging for large-volume distributors, and retail blister card or clamshell packaging for trade counter and hardware store supply. Export cartons are double-walled with silica gel desiccant to prevent tarnishing during sea freight transit. Custom branding, private labelling, and barcode labelling are available.

Q10. Do brass conduit connectors require a bonding/earth connection?

Metallic flexible conduit systems used as equipment grounding conductors (EGC) require the conduit connector to provide a continuous electrical path between the conduit and the enclosure. Our brass connectors achieve this through metal-to-metal contact. For installations where the conduit is not used as EGC, a supplementary earth wire can be run inside the conduit. Swivel connectors maintain electrical continuity through the rotating contact surface.

Q11. What is your minimum order quantity (MOQ)?

For standard catalogue sizes, our MOQ is typically 100–500 pieces per size per type. For full range distributors placing blanket orders covering multiple sizes, we can reduce per-size MOQ further. Sample quantities (5–20 pieces per size) are available for approval and testing prior to production order placement. Contact our sales team for volume pricing tiers.

Q12. Are your connectors UL listed or CE marked?

Our brass conduit connectors are manufactured to UL 514B and IEC 60423 dimensional and performance standards. CE marking under the Low Voltage Directive (LVD 2014/35/EU) is the responsibility of the electrical panel builder who incorporates our components. We can provide material test certificates, dimensional inspection reports, and third-party testing reports (SGS, Bureau Veritas) to support your compliance documentation.

Q13. How do nickel-plated connectors perform in marine environments?

Nickel-plated brass connectors significantly outperform natural brass in marine and coastal environments. The 5–10 µm nickel layer acts as a barrier against salt water chloride ions that cause dezincification of brass alloys. Our nickel-plated connectors have been salt-spray tested to 500 hours per ASTM B117 without base metal exposure. For fully immersed marine applications, we recommend our stainless steel cable gland range for maximum longevity.
