Welcome to our Conduit Fittings category, where you'll find essential components for protecting and organizing electrical wiring. These fittings, including squeeze connectors, set-screw connectors, straps, and hangers, ensure secure connections and support for conduits in residential, commercial, and industrial applications. Whether you're a DIY enthusiast wiring a garage or a professional electrician tackling a large project, reliable conduit fittings are crucial for safety, compliance with electrical codes, and long-term durability.
What Are Conduit Fittings and Why Do They Matter?
Conduit fittings are specialized hardware designed to join, support, secure, and terminate electrical conduits. Conduits themselves protect wires from damage, moisture, and physical impact, but without proper fittings, installations can fail inspections or pose hazards. In this category, you'll see products like the Sigma Engineered Solutions ProConnex 49804 AC/MC/Flex 90-Degree Squeeze Connector for flexible applications and RACO's set-screw connectors, straps, and hangers tailored for EMT, rigid, and IMC conduits.
Choosing the right fittings prevents loose connections, vibrations, and exposure to elements, extending the life of your electrical system. They're indispensable for running wires through walls, ceilings, or outdoors, making them a staple in any Electrical Boxes, Conduits & Fittings setup.
Types of Conduit Fittings Available
Our selection covers key types to match various conduit materials and project needs:
- Squeeze Connectors: Ideal for AC, MC, or flex conduits, these provide a quick, tool-free squeeze for a tight seal. The 1/2-inch Sigma ProConnex model excels in tight spaces for branch circuits.
- Set-Screw Connectors: For EMT steel conduits, these use screws for a rock-solid hold. RACO's 3/4-inch uninsulated version in a 5-pack offers value for multiple runs.
- Straps and Hangers: Secure conduits to surfaces or structures. RACO's 1/2-inch one-hole straps (25-pack) and 3/4-inch bolt hangers (5-pack) support straight runs and drops, preventing sagging.
These steel fittings, often in gray finishes, resist corrosion and meet UL standards for indoor/outdoor use.
Key Features to Consider When Shopping
Select conduit fittings based on these buyer-focused criteria:
- Trade Size: Match your conduit—1/2-inch for light residential, 3/4-inch for heavier gauges.
- Material and Insulation: Steel for strength; uninsulated for cost savings where grounding is handled separately.
- Connection Type: Squeeze for flex, set-screw for rigid EMT, straps/hangers for mounting.
- Pack Quantity: Bulk packs like RACO's 25 straps suit big jobs; singles for spot needs.
- Approval Ratings: Look for UL-listed for code compliance.

Common Use Cases for Conduit Fittings
These fittings shine in diverse scenarios:
- Residential Wiring: Secure EMT runs in basements or garages using straps and connectors.
- Commercial Builds: Rigid/IMC hangers support overhead lighting or HVAC controls.
- Outdoor/Industrial: Squeeze connectors for flexible MC cable in exposed areas.
- Renovations: Quick-install options minimize downtime.

Installation Tips for Success
Proper setup ensures safety:
- Measure twice: Confirm trade size matches conduit OD.
- Tighten securely: Use torque specs for set-screws to avoid over-crimping.
- Space supports: Straps every 10 feet, hangers per code for vertical runs.
- Ground properly: Uninsulated types require separate bonding.
Always consult local codes and use tools like conduit benders from Tools & Home Improvement.
What is the difference between EMT and rigid conduit fittings?
EMT fittings like set-screw connectors work with thinner-walled electrical metallic tubing for indoor use. Rigid/IMC fittings, such as compression types or hangers, handle thicker walls for heavier-duty or outdoor applications.
How do I choose the right size conduit fitting?
Match the trade size (e.g., 1/2-inch or 3/4-inch) to your conduit's nominal diameter. Check product specs for compatibility with EMT, flex, or rigid types.
Are these fittings suitable for wet locations?
Many steel models are, but verify UL wet-location ratings. RACO options often include corrosion-resistant coatings for damp areas.
Can I mix brands like RACO and Sigma?
Yes, as long as sizes and types match. RACO excels in straps/hangers, while Sigma offers specialized squeeze connectors.
What's the best way to mount conduit straps and hangers?
Use appropriate screws into studs/joists. For hangers, thread bolts through for adjustable drops, ensuring level alignment.
