Cooper Crouse-Hinds C28 Condulet Form 8 Conduit Outlet

Name: Cooper Crouse-Hinds C28 Condulet Form 8 Outlet – Datasheet
Brand: Cooper Crouse-Hinds

Description

Overview

The Cooper Crouse-Hinds C28 is a Condulet Form 8 conduit outlet body designed for straight-through rigid conduit runs that need generous internal volume for heavier conductors, splicing, or tapping. Sized for 3/4-inch trade conduit with two in-line hubs, the C28 is a Type C body, meaning both hub openings sit on the same axis – the configuration used wherever a conduit run needs a straight pull outlet, an inspection point, or a legal splice location without introducing a bend. Its Form 8 body style provides substantially more interior room than a standard Form 5 fitting of the same trade size, which matters when a run carries larger-gauge conductors, multiple circuits, or thick insulation that would otherwise crowd a smaller enclosure.

With fast quotation turnaround and technical support, Seven Star LLC proudly supplies the C28 Condulet Form 8 conduit outlet to contractors, EPC firms, and plant maintenance teams across the Sultanate of Oman and the wider GCC.Seven Star LLC supplies this item on request with the manufacturer documentation, and availability and lead time are confirmed at quotation.

Operating Principle

Like other Condulet outlet bodies, the C28 is a passive raceway component, but its Form 8 geometry is a deliberate engineering response to conductor fill limits set by electrical code. Where a Form 5 body might be adequate for lighter circuits, the extra internal cross-section of a Form 8 body allows larger conductors, additional circuits, or bulkier insulation systems to be pulled, bent to the required minimum radius, and terminated without exceeding safe fill percentages. The two straight-through hubs use tapered NPT threads with integral bushings that protect conductor insulation as wire is drawn through the casting, and the gasketed cover interface keeps the enclosure sealed against dust and moisture once conductors are terminated.

The practical result is a conduit body that functions as both a mechanical pull point and a legal splice or tap enclosure, with no moving parts and no maintenance requirement beyond periodic inspection of the cover gasket. Because the body accepts a standard bolted or screw-on Form 8 cover, technicians can reopen the fitting at any time during the life of the installation to inspect terminations, add a tap, or re-pull conductors – a capability that matters on long-term industrial assets across Oman where conduit systems are expected to remain serviceable for decades under harsh coastal and desert conditions.

Engineering Design of the Cooper Crouse-Hinds C28

The C28 is cast from Feraloy, a Crouse-Hinds proprietary iron alloy selected for its combination of mechanical strength and corrosion resistance in demanding industrial environments. The casting receives a dual finish – electro-galvanized plating beneath an aluminum acrylic paint topcoat – that gives the fitting substantially better long-term corrosion performance than a single-layer finish, an important factor for conduit runs exposed to the humidity, salt spray, and temperature swings typical of Gulf coastal industrial sites.

Physically, the C28 measures approximately 6.28 inches in length, 1.69 inches in height, and 1.19 inches in width, with two 3/4-inch tapered NPT hubs on a common axis and a weight of roughly 1.44 lb. The fitting is rated NEMA 12 for protection against dust, dirt, and non-corrosive liquid splash, and it is listed to UL 514B, built to Federal Specification W-C-586D, and certified under CSA C22.2 No. 18 – the recognized standards referenced across most Gulf-region EPC electrical specifications for conduit bodies used on rigid metal conduit systems.

Key Features

The Cooper Crouse-Hinds C28 pairs a rugged Feraloy iron alloy casting with a generously sized Form 8 interior, and the following features summarize why it is specified across heavy industrial and utility conduit systems in Oman and the GCC.

Feraloy iron alloy body construction delivers high mechanical strength for demanding industrial and outdoor conduit installations.
Form 8 design provides extra interior room compared to standard Form 5 bodies, accommodating heavier conductors and additional circuits.
Electro-galvanized plating beneath an aluminum acrylic paint finish gives dual-layer corrosion protection in humid and coastal environments.
3/4-inch trade size, two in-line hubs configured for straight-through Type C conduit runs.
Tapered NPT threaded hubs with integral bushings protect conductor insulation during installation and future maintenance.
NEMA 12 rating protects against dust, dirt, and non-corrosive liquid splash on industrial floor and outdoor installations.
Listed to UL 514B and built to Federal Specification W-C-586D, meeting the standards referenced in most regional EPC specifications.
CSA C22.2 No. 18 certified and NEC/CEC compliant, supporting both North American and Gulf-region project code requirements.

Industrial Applications

The C28 is specified wherever a straight-through 3/4-inch rigid conduit run needs a splice, tap, or pull point with more interior room than a standard body provides. Typical placements include motor and pump feeder circuits, lighting and power distribution runs in process and utility areas, instrumentation conduit routing where multiple signal cables share a raceway, and long straight conduit runs across process units where periodic access points are required by code for conductor management and inspection.

About brand

Crouse-Hinds is the American brand of explosion-proof and hazardous-area electrical equipment: Condulet conduit bodies, explosion-proof enclosures, control stations, plugs and receptacles, lighting and cable glands. Huntington B. Crouse and Jesse L. Hinds founded the company in Syracuse, New York, on 18 January 1897; its first product was a changeable headlight for trolley cars. Crouse-Hinds became part of Cooper Industries in 1981 and has been an Eaton brand since Eaton acquired Cooper in 2012.

Seven Star LLC sources and supplies Cooper Crouse-Hinds conduit fittings, sealing fittings, junction boxes, pushbutton stations and receptacles for plants in Oman, checking each catalog number against the manufacturer's documentation. Current production is sold as Eaton's Crouse-Hinds series, so either name may appear on the part you are replacing.

Where Crouse-Hinds explosionproof equipment is used

Most of these parts belong to rigid conduit systems in classified areas: refinery units, gas compression and metering stations, tank farms, loading racks, paint and solvent handling, and offshore modules across the GCC. The listed series are built around the North American Class and Division system, but the rating differs by item: N2S stations are marked for Class I, Division 2, and the AR342 receptacle is a watertight type for ordinary locations. A Cooper Crouse-Hinds junction box or control station should therefore be selected against the area classification drawing, not by enclosure size alone.

FAQ

Questions about the Cooper Crouse-Hinds C28 Condulet Form 8 Conduit

Answers from our engineering team on installation, compatibility and integration.

01What is the Cooper Crouse-Hinds C28 used for?

The C28 is a 3/4-inch Type C Form 8 conduit outlet body used on straight-through rigid conduit runs to provide a pull point, splice location, or tap access where extra interior room is needed for heavier conductors.

02How is the C28 different from a standard Form 5 conduit body?

The C28 uses a Form 8 casting, which provides significantly more interior volume than a comparable Form 5 body of the same trade size, allowing larger conductors, additional circuits, or bulkier insulation to be accommodated within code fill limits.

03What conduit sizes and materials is the C28 compatible with?

The C28 is sized for 3/4-inch trade conduit and is intended for rigid metal conduit systems, using tapered NPT threaded hubs with integral bushings that protect conductor insulation during installation.

04Can the C28 be reopened for maintenance after installation?

Yes. The C28 accepts a standard Form 8 cover that can be removed at any time for inspection, re-pulling conductors, or adding a splice or tap, without disturbing the rest of the conduit run.

05Is Seven Star LLC an experienced supply partner for Cooper Crouse-Hinds products?

Yes. Seven Star LLC supplies Cooper Crouse-Hinds products to customers in Oman and the GCC and can provide the manufacturer documentation and technical support on request.
