Explosion proof connector, also called explosion proof fittings, explosion proof electrical fittings, flame proof fittings, flameproof electrical fittings, hazardous location fittings, explosion proof electrical connectors, explosion proof cable connectors, hazardous area plugs, 1 2 explosion proof union, explosion proof reducing bushing, 1 to 3 4 reducing bushing, 3 4 to 1 2 reducer bushing, 1 2 to 3 4 enlarger, 3 4 emt pull elbow, explosion proof 3 piece coupling.
Explosion proof connector are cylinder shape union widely used to connect conduit to explosion proof enclosure, conduit, conduit fittings, junction box or device enclosure in rigid conduit system in hazardous location. Through flame proof metal body isolating the explosion ignition inside the body or increased safety body containing electrical spark, explosion proof connector permit enclosures removal without conduit disassembly, change the conduit direction in tighter space and allow for expansion or contraction of conduit size to facilitate modification. Material ranges from carbon steel, nickel plated brass to stainless steel.

Main Usage
Explosion Proof Connector
Explosion proof connector can be used in many working places, now we are listing the main usage fields from four aspects, function, hazard class division, usage by application and alternative for brand-new models.
Function
Explosion proof connector can be installed to change the thread type and size on the housing of explosion proof light and explosion enclosure, change the conduit direction for rigid conduit system, fix the rigid conduit and liquid-tight conduit tightly to explosion proof enclosure in explosive atmosphere.
Hazard class division
You know there are different classifications and divisions for explosion proof switch, hazard class division can be class 1 div 1 and class div 2, gas group A, B, C, D, class 2 division 1 and class 2 division 2, dust group E, F, G, zone 1 and zone 2, gas group IIC, zone 21 and zone 22, dust group IIIC.
Usage by application
Depends on the application field, explosion proof connector can be used in where explosion proof lighting and explosion proof enclosure installed, such as liquefied nature gas plant, liquefied petroleum gas plant, and chemical plant anywhere there is combustible gas, vapor, mist and dust.
Alternative for brand-new model
SUREALL explosion proof connector is the alternative connector solution for 3 4 emt pull elbow, unf catalogue, unf connector, 1 2 to 3 4 enlarger, bgj connector, unf union, una union, unl union, el elbow, 1 to 3 4 reducing bushing, 3 4 to 1 2 reducer bushing, myers hubs, liquidtight fittings.
What is Explosion Proof Connector?
Explosion proof connector are designed with flame proof Ex d thread joint to thread of conduit or explosion proof housing hubs to prevent any explosion from running outside in hazardous location.
There are 4 types of explosion proof connectors for enclosure drilled hubs or rigid conduit as below:
SA series explosion proof adapters connect two same or similar conduit hubs sizes together from two conduits ends
SR series explosion proof reducer reduce two different conduit hubs sizes from a larger size to smaller size from two conduits ends
SU series explosion proof unions connect two same or similar conduit hubs sizes together from two conduits ends with detachable assembly for 3 pieces.
SE series explosion proof elbows change direction in threaded rigid conduit with 90°or 45°angle

There are two types of explosion proof connector to terminate the rigid conduit or liquid-tight conduit as below:
SH series explosion proof conduit hub is widely used to connect rigid conduit, such as rigid metal conduit (RMC), intermediate metal conduit (IMC) and electrical metal tubing (EMT).
SL series explosion proof liquid-tight connector is widely used to connect liquid-tight flexible metal conduit (LFMC).

FAQ for Explosion Proof Connector
Q
What is a conduit adapter?
A
SUREALL SA series Explosion proof conduit adapter is conduit connector and fittings in explosive protected environment to connect one threaded end of conduit to another conduit, one threaded hub of explosion proof lighting, explosion proof junction box, explosion proof enclosure to another conduit, one threaded hub of explosion proof lighting to another metal explosion proof cable gland, the thread of ends are same or similar, such as NPT 3/4’’ to M25x1.5 thread.
Q
What is a reduction bushing? What are reducer bushings used for?
A
SUREALL SR series explosion proof reduction bushing is conduit connector, reducer, enlarger in hazardous classified area to connect one threaded end of conduit to another rigid conduit, one threaded hub of explosion proof lighting, explosion proof enclosure, explosion proof panel and explosion proof fittings to another conduit, one threaded hub of explosion proof enclosure to another metal explosion proof cable gland or fittings, whereas, the thread of ends are different, like NPT3/4″ to NPT 1/2″.
Q
What is a conduit union?
A
SUREALL SU series explosion proof conduit union is the same function of explosion proof SA series explosion proof conduit adapter, but it is specially designed with a detachable assembly part for undocking the connected explosion proof lighting and explosion proof enclosure from the conduit with no need to disassembly the heavy shape device to save the labor, this conduit union also can be used as explosion proof 3 piece coupling.
Q
What is a Myers hub?
A
Myers hub is explosion proof conduit hub to worked as conduit connector to end up the conduit. SUREALL explosion proof conduit hub SH series can be installed at the threaded hubs of cable entry of the wall of explosion proof enclosure to bring cable into the terminal blocks and electrical device, it is widely used for class 1 div 1 explosion proof enclosure for oil and gas industry.
Q
Is liquid tight conduit explosion proof?
A
No, liquid tight conduit is not explosion proof, but if you install SUREALL SL series explosion proof liquid-tight connector on both ends of liquid tight conduit, then the liquid tight conduit can be used as class 1 div 2 hazardous location, zone 1 explosive atmosphere.
