The best 3/4-inch FMC connector depends on how you need to attach flexible metal conduit: a straight squeeze connector is a common choice for a box connection, while a screw-in fitting terminates conduit at a knockout. The Yaocom 50-pack suits buyers needing many fittings; the AIRTAK 90-degree pair is for angled connections; and the Sigma and RACO screw-in options are for steel FMC and 3/4-inch knockouts. Compare connection style and package quantity before selecting a fitting.
| Product | Best for | Connection style |
|---|---|---|
| Yaocom 50-Pack | Bulk projects | Squeeze |
| AIRTAK 2-Pack Elbow | Right-angle routing | 90-degree squeeze |
| Sigma ProConnex GC-75 | Steel FMC at a knockout | Screw-in |
| AIRTAK 5-Pack Straight | Small projects needing several straight fittings | Squeeze and locknut |
| RACO 2283 | Metal screw-in fitting in a larger pack | Screw-in |
Yaocom 50-Pack 3/4-Inch Squeeze Connectors
This 50-pack is described as 3/4-inch squeeze connectors for FMC and electrical conduit fittings. Its main advantage is quantity: it is best for larger wiring jobs, repeated installations, or buyers who want a supply of matching squeeze-style fittings. The product name also references box cable connectors, making it relevant when planning a conduit-to-box connection.
Why choose it: The large pack is better suited to multi-connection work than a two- or five-piece set. Limitation: The supplied listing information does not specify material, installation details, or certifications, so confirm those requirements before purchase.
AIRTAK 90-Degree Squeeze Connector Pair
This two-pack combines a 3/4-inch flexible metal conduit elbow with a 90-degree squeeze connection. It is best for a route that needs to turn at a right angle rather than enter a fitting in a straight line. The listed die-cast zinc alloy construction has a smooth, burr-free interior and an anodized anti-oxidation coating. The squeeze-to-connect design is described as tool-free.
Why choose it: The elbow shape addresses angled routing, and two fittings can support more than one connection or a replacement. Limitation: The listing describes use in dry environments, so avoid choosing it for a location that requires a different environmental rating.
Sigma ProConnex GC-75 Screw-In Connector
The Sigma ProConnex GC-75 is a 3/4-inch flex screw-in connector sold in a 25-pack. Its listed purpose is terminating steel 3/4-inch FMC to a 3/4-inch knockout. It is best for buyers who specifically need a screw-in connection at that opening, rather than a squeeze fitting or an elbow.
Why choose it: The product details clearly identify both the conduit type and knockout size, while the 25-piece quantity suits repeated installations. Limitation: The stated application is steel FMC; verify conduit type and knockout dimensions rather than assuming it suits other setups.
AIRTAK 5-Pack Straight Squeeze FMC Connectors
This five-pack is described as straight connectors for standard 3/4-inch FMC and electrical boxes. It uses zinc die-cast construction and a screwdriver-tightened locknut. The listing calls the design fully insulated and non-grounding, and says it is intended for low-voltage residential wiring where a separate ground path is not required.
Why choose it: It is a practical middle ground between a single fitting and a bulk pack, especially when controlled, screwdriver-based tightening is preferred. The listing states that the product name identifies it as UL listed. Limitation: Its non-grounding design is not appropriate where the connector must provide the grounding path.
RACO 2283 Steel Screw-In Connector
The RACO 2283 is a 3/4-inch screw-in connector for flexible metal conduit, packaged as 25 pieces. Its listed feature is rugged metallic construction intended to provide mechanical protection for the raceway. It is best for buyers seeking a metal screw-in fitting in a larger quantity.
Why choose it: The screw-in design and 25-piece pack make it a comparison option for recurring FMC termination work. Limitation: The provided details do not state a specific knockout size or material grade, so check the product specifications against the installation needs.
Buying Guide: How To Choose A 3/4-Inch FMC Connector
Should you choose squeeze or screw-in?
A squeeze connector clamps the FMC through a squeeze mechanism or related tightening hardware. A screw-in connector is designed to terminate conduit at a compatible knockout. Choose based on the fitting and enclosure connection required; the styles are not interchangeable by assumption. Check whether the particular product calls for hand compression, a screwdriver, or another installation method.
Do you need a straight fitting or an elbow?
Use a straight connector when the conduit approaches the box or enclosure in a straight path. Choose a 90-degree elbow when the route needs to turn at the connection. An elbow can help with direction changes, but the available product details do not establish that every enclosure layout will have adequate space, so confirm dimensions for the installation.
What does 3/4 inch refer to?
These products are identified as 3/4-inch fittings for 3/4-inch FMC or a 3/4-inch knockout, depending on the model. Match the connector to the conduit and enclosure opening specified by its manufacturer. Do not rely on appearance alone when confirming nominal trade size or fit.
How many connectors should you buy?
Estimate the number of conduit terminations first, then allow for replacements if appropriate. A two-pack suits a limited job or pair of connections, a five-pack covers a small set of fittings, and 25- or 50-piece packs are aimed at larger or repeated work. Package size does not determine whether a connector is right for a specific application.
What material and grounding details matter?
Compare the stated construction, installation method, environmental limits, and grounding design. For example, the AIRTAK straight fitting is described as non-grounding, while the elbow listing specifies dry-environment use. Confirm that the product’s stated features meet the project requirements and applicable electrical rules. Consult a qualified electrician when the correct connector or grounding method is uncertain.
Frequently Asked Questions
What is a 3/4-inch FMC connector used for?
It joins compatible 3/4-inch flexible metal conduit to an electrical box or other specified termination point. The exact connection depends on the fitting design.
Can a squeeze connector replace a screw-in connector?
Not automatically. They use different connection styles, so choose the type specified for the conduit-to-enclosure connection.
When should I use a 90-degree FMC connector?
Use a 90-degree elbow when the conduit needs to change direction at the fitting. Check the product and installation dimensions before selecting it.
Are all 3/4-inch connectors grounding connectors?
No. The AIRTAK straight connector is specifically described as non-grounding. Review each product’s grounding information and provide the required grounding path.
Does a 3/4-inch connector fit every electrical box?
No. Confirm the box opening or knockout size and the connector’s stated application. A 3/4-inch fitting should not be assumed to fit a different-sized opening.
