Thread Reducers, Enlargers and Thread Adapters for Conduit Fittings
Thread reducers, enlargers, and thread adapters are used to adapt thread sizes and thread standards for threaded conduit fittings and other threaded electrical devices.
These components allow conduit fittings to connect securely to electrical panels, enclosures, junction boxes, and machine housings where thread size or thread standard differences exist.
Reducers allow smaller threaded fittings to connect to larger threaded entries, while enlargers allow larger fittings to be installed in smaller threaded openings. Thread adapters convert between thread standards such as Metric and PG conduit fitting threads.
FLEXAquick® quick-connect fittings and ROHRflex® flexible corrugated conduits are flagship product lines from IBIS Electro-Products Corp., specializing in high-performance electrical conduit systems.

Thread reducers, enlargers, and thread adapters provide a mechanical interface between threaded conduit fittings and threaded entries in electrical enclosures and equipment housings.
Thread enlargers allow larger conduit fittings to connect to smaller threaded openings. Thread reducers allow smaller fittings to be installed in larger threaded entries.
Thread adapters convert between different thread standards such as Metric and PG.
Flange fitting adapters convert a straight or elbow threaded fitting into a flanged fitting, improving mounting stability when a panel entry or knockout opening is not rigid enough to secure a threaded fitting and locknut alone
Typical applications for thread reducers and adapters include:
• Industrial automation systems
• Electrical panels and enclosures
• Machine wiring systems
• Robotics and packaging equipment
• Railway and transit vehicle electrical systems
• Retrofit conduit installations
• Equipment housings requiring threaded conduit entries
Frequently Asked Questions About Thread Adapters and Reducers
When should a thread reducer be used?
Thread reducers are used when a threaded conduit fitting has a smaller thread size than the threaded opening in the panel, enclosure, or equipment housing.
How do I know whether I need a thread reducer or a thread enlarger?
Installers typically start with the panel or enclosure knockout size and then match the conduit fitting to that opening.
If the knockout opening is smaller than the fitting thread, a thread enlarger is used.
If the knockout opening is larger than the fitting thread, a thread reducer is used.
Thread adapters are used when the thread standard differs, such as converting between Metric and PG threads.
When should a thread enlarger be used?
Thread enlargers allow larger threaded conduit fittings to be installed in smaller threaded entries without modifying the enclosure.
What is the difference between a thread reducer and a thread adapter?
Thread reducers change the thread size, while thread adapters convert between thread standards such as Metric and PG.
What is a flange fitting adapter used for?
Flange fitting adapters convert straight or elbow threaded fittings into flanged fittings to improve mounting stability when panel entries are not rigid enough for secure fitting and locknut installation.
Can thread adapters be used with cable glands or strain relief fittings?
Yes. Thread reducers, enlargers, and adapters can be used with threaded conduit fittings, cable glands, strain relief fittings, cord grips, and other threaded electrical devices.
