Eaton Crouse-Hinds 1033DC Throat Bushing - Rigid/IMC
Part Number: 1033DC
Quick Summary
1033DC throat bushing offers secure, threaded connections for rigid/IMC conduit in industrial electrical installations. In busy panels, space constraints and compatibility gaps slow wiring and increase field errors. This non-ins insulated, zinc die-cast bushing supports ordinary/non-hazardous locations and aligns with NEC/CEC requirements, while UL certification adds confidence in rigid-IMC use. Its compact 1 in trade size and lightweight 0.04 lb body simplify stocking, handling, and installation in tight enclosures. Designed for reliability, it reduces rework and supports scalable electrical distributions across machines and panels. For engineers and procurement teams, the combination of robust construction and standard sizing delivers better project predictability and lower total cost of ownership.

Eaton Specification Sheet - 1033DC
Feature: Compatibility with rigid/IMC conduit. Business Impact: Secure mechanical coupling reduces misfit risk, field rework, and re-torque calls, accelerating commissioning in tight panel layouts. Application: Designed for electrical panels, motor control centers, and enclosures where threaded, metal-to-metal connections for rigid or IMC conduit are required, ensuring reliable pathway integrity long after initial energization. Feature: Non-insulated zinc die-cast body. Business Impact: Provides robust durability and corrosion resistance without the maintenance overhead of insulating components, lowering lifecycle costs. Application: Suitable for indoor industrial plants and control rooms where metal-to-metal bushing connections must withstand frequent temperature cycling and mechanical wear. Feature: Threaded 1 in trade size. Business Impact: Standardized fitting size reduces procurement complexity and spares the need for adapters, delivering faster stocking and quicker replacements. Application: Fits common 1 in conduit runs in control panels and machine enclosures. Feature: Compact dimensions and light weight. Business Impact: Simplifies retrofit projects, reduces enclosure crowding, and lowers shipping and inventory costs. Application: Tight spaces and retrofit upgrades where length, width, and height are key constraints. Feature: Compliance and certification readiness. Business Impact: NEC/CEC alignment with UL certification for rigid-IMC fittings reduces regulatory risk and accelerates approvals. Application: Industrial facilities in Ordinary/Non-Hazardous locations requiring safety certification and code compliance.

FAQs
To install, align the conduit and thread the bushing into the corresponding enclosure or knockout until hand-tight, then snug with an appropriate tool. Ensure the connection remains metal-to-metal and that the conduit is seated fully. Verify NEC/CEC compliance and UL readiness after installation, and perform a quick torque check to prevent loosening under vibration.
The 1033DC features a length of 1.67 in, height of 0.91 in, width of 0.95 in, and a weight of 0.04 lb. It is designed for 1 in trade size threaded connections and is compatible with rigid/IMC conduit. These compact dimensions support easy routing in tight enclosures while maintaining robust mechanical integrity.
The product is specified for Ordinary/Non-Hazardous Locations, ensuring compliance with NEC/CEC for standard indoor electrical installations. It should not be used in hazardous or outdoor locations unless additional enclosure protection and suitable environmental ratings are provided as part of the overall system design.
The 1033DC is designed to meet NEC/CEC standards and is UL certified for rigid-IMC applications. It uses a non-insulated zinc die-cast body and is intended for Ordinary/Non-Hazardous locations, aligning with typical industrial safety and performance requirements.
The 1033DC offers durable zinc die-cast construction that resists corrosion, reducing replacement frequency. Its 1 in trade size and threaded design enable faster installation and easier stocking, lowering labor time and inventory costs. Together with NEC/CEC compliance, UL readiness minimizes regulatory bottlenecks and supports faster project closeouts.
