In hazardous industrial environments — from oil refineries and chemical plants to power stations and marine facilities — electrical safety is non-negotiable. Form 7 Conduit Bodies are critical components in explosion-proof wiring systems, providing safe, accessible junction points that protect wiring connections from environmental and mechanical damage.
OMEJA CASTING, a leading manufacturer of ductile iron and aluminum electrical fittings, produces high-strength Form 7 conduit bodies designed to meet NEC and IEC standards for explosion-proof electrical installations.
Form 7 Conduit Bodies are metallic enclosures installed in rigid conduit systems to:
Provide access for wire pulling, splicing, and maintenance
Serve as junction or bend points in conduit runs
Maintain the integrity of the explosion-proof system
They are typically made from ductile iron, aluminum, or malleable iron, depending on environmental requirements. Each unit includes a gasketed cover to seal the interior against moisture, dust, and gas ingress.
OMEJA’s Form 7 series is precision-cast to ensure tight sealing, corrosion resistance, and durability under extreme field conditions.
Explosion-proof conduit systems rely on precise component design to contain or prevent ignition. OMEJA’s Form 7 conduit bodies are engineered in accordance with Class I, Division 1 & 2 (gas/vapor) and Class II, Division 1 & 2 (dust) standards.
Explosion-proof features include:
Thick-walled ductile iron construction for high mechanical strength
Precision-machined flame paths to contain internal ignition
Threaded hubs for secure and gas-tight conduit connections
Corrosion-resistant coatings for long-term outdoor and offshore use
Each unit undergoes pressure and leakage testing, ensuring compliance with UL and NEC safety requirements.
While aluminum bodies are common in lightweight installations, ductile iron Form 7 conduit bodies offer unmatched impact resistance and explosion containment.
Key material advantages:
High tensile strength (≥ 450 MPa) and ductility prevent cracking under load.
Excellent vibration resistance, suitable for industrial and marine settings.
Superior corrosion protection when hot-dip galvanized or epoxy coated.
Dimensional stability ensures consistent threading and cover sealing.
OMEJA CASTING uses EN-GJS-450-10 and ASTM A536 80-55-06 ductile iron grades to balance strength, machinability, and toughness.
The Form 7 series includes several body configurations, each serving a specific conduit routing function.
Type | Shape | Application |
LB | 90° angle with back opening | For right-angle conduit bends and wire pulling |
LL | 90° angle with left opening | Ideal for wall-mounted conduit runs |
LR | 90° angle with right opening | Used in vertical-to-horizontal transitions |
T | Tee-shaped body | Joins three conduit lines at 90° angles |
C | Straight-through | For inline splicing and maintenance access |
X | Cross-type | Connects four conduits in intersecting lines |
OMEJA CASTING offers these in multiple hub sizes (½" to 4") with NPT threaded hubs and weatherproof covers, ensuring full compatibility with North American and IEC conduit systems.
To enhance corrosion resistance and extend service life, OMEJA provides multiple surface treatment options:
Hot-dip galvanizing for outdoor and coastal installations
Epoxy powder coating for chemical and offshore environments
Anodized aluminum finishing for lightweight, corrosion-resistant versions
These coatings meet ASTM B117 salt spray test and ISO 12944 corrosion category standards, ensuring durability even in highly corrosive atmospheres.
OMEJA’s Form 7 conduit bodies are widely used in:
Oil and Gas Facilities – for Class I, Division 1 explosion-proof wiring.
Chemical Plants – providing sealed junctions resistant to corrosion.
Power Generation and Transmission – protecting outdoor conduit networks.
Marine and Offshore Platforms – withstanding salt spray and vibration.
Grain Processing and Dust Industries – meeting Class II hazardous area requirements.
Their reliability under high pressure, temperature, and vibration makes them essential in critical safety systems.
With advanced ductile iron casting technology and a strong focus on electrical enclosure precision, OMEJA CASTING produces explosion-proof conduit fittings that meet international specifications and customer customization needs.
Core strengths:
ISO-certified foundry and machining facilities
Precision metal molds ensuring consistent dimensions
In-house galvanizing and powder-coating lines
