Bx-Flex Conduit Fitting, Set Screw Type
Bx-Flex Conduit Fittings, Set Screw Type, S11/S12/S13/S14/S18/S24 series are certified by UL laboratory according to UL514B. The metal fittings are applied on the relay or end point of wiring system to connect metal conduits, junction box or enclosure for wiring extension and protection. The fitting body is made of zinc alloy with RoHS compliance. The fitting is pushed to fix/fixed to the knockouts of junction box or tapped entries by locknut with external NPS thread system and connected with metal flexible conduit by a set screw and a clip. This series of fitting is proposed to fit with metal flexible conduit series PRWG and PRWA.

Frequently Asked Questions
What UL certifications do BX Flex Conduit Fittings have?
Our BX Flex Conduit Fittings are certified by UL laboratory according to UL514B standard and Canadian CSA-C22.2 No.56 standard. These certifications ensure that our products meet the highest safety and quality standards for electrical conduit fittings in North America. All our fittings are UL Listed/Recognized and comply with NEC (National Electrical Code) requirements.
How do I choose the correct fitting model for my application?
Selecting the right fitting depends on several factors:
Conduit Size: Match the fitting size to your conduit diameter (available from 3/8" to 4")
Installation Method: Choose Set Screw Type (S10-S15, S18, S24) for standard applications, Squeeze Type (S22, S23, S25) for quick installation, or Two Screw Type (S19-S21) for secure connections
Space Constraints: Use 90-Degree fittings (S22/S23) for limited spaces or tight corners
Mounting Style: Select locknut types for threaded knockouts or snap-in types for tool-free installation
Our compatible conduit series include PRWG (Galvanized Steel) and PRWA (Aluminum) Flexible Metal Conduits.
What is the difference between Set Screw Type and Squeeze Type fittings?
Set Screw Type (S10/S11/S12/S13/S14/S15/S18/S24):
Connected to conduit using a set screw and clip mechanism
Provides strong, permanent connection
Ideal for applications requiring high pull resistance
Fixed to junction box knockouts with locknut and external NPS thread
Squeeze Type (S22/S23/S25):
Connected by squeezing/tightening the cover with two screws
Faster installation process
Excellent for field modifications and quick connections
S22/S23 series features 90-degree elbow design for space-saving installations
Are these fittings suitable for outdoor or harsh environment applications?
BX Flex Conduit Fittings are designed primarily for indoor and dry location applications. They provide IP40 protection rating. For outdoor, wet locations, or harsh environments with exposure to moisture, oil, or chemicals, we recommend our Liquid Tight Flexible Metal Conduit Fittings (UL 360) which offer superior environmental protection.
The zinc alloy construction with chromate surface finish provides corrosion resistance for normal indoor environments. All materials are RoHS compliant and environmentally friendly.
What materials are used in manufacturing these fittings?
Our BX Flex Conduit Fittings are manufactured with premium quality materials:
Body Material: Zinc alloy die-cast construction for durability and strength
Surface Finish: Chromate treatment (other finishes available upon request)
Compliance: All materials are RoHS compliant, meeting environmental and safety standards
Thread System: External NPS (National Pipe Straight) thread for secure connection to junction boxes and enclosures
Can these fittings be used with aluminum flexible conduit?
Yes! Our BX Flex Conduit Fittings are compatible with both:
PRWG Series: Galvanized Steel Flexible Metal Conduit (Reduced Wall)
PRWA Series: Aluminum Flexible Metal Conduit (Reduced Wall)
The fittings are designed to provide secure connections with either conduit type, ensuring versatility for different project requirements and specifications.
What is the temperature range for these fittings?
BX Flex Conduit Fittings can operate safely in temperatures ranging from -50°C to +200°C (-58°F to +392°F). This wide temperature range makes them suitable for various applications including:
Commercial buildings and office environments
Light fixtures and lighting systems
Data centers and server rooms
Industrial machinery and equipment
Elevator installations

What is the difference between snap-in and locknut installation types?
Snap-In Type (e.g., S19, S23):
Tool-free installation - simply push into knockout holes
Faster installation, ideal for high-volume projects
Works with standard circular knockouts in junction boxes
UL514B certified for secure connection
Locknut Type (e.g., S20, S21, S22):
Fixed with external NPS threaded locknut
Provides more rigid and permanent installation
Better suited for applications with vibration or movement
UL514B and CSA-C22.2 No.56 dual certified
