FAQs
H1033 installs like a standard 1" throat bushing for rigid/IMC conduit. Align the threaded exterior with the conduit entry, tighten with an appropriate wrench to the manufacturer’s torque spec, and verify insulation integrity before re-energizing. Its insulated design helps prevent arcing and moisture ingress at entry points, improving long-term reliability.
H1033 is made from malleable iron and rated for 150°C. The combination of sturdy material and high temperature rating maintains mechanical protection and insulation integrity in high-heat environments, such as near motor drives or enclosed electrical panels, reducing risk of insulation degradation and extending service life in demanding automation settings.
Yes. H1033 supports NEC/CEC standards and is certified for use in ordinary/non-hazardous locations. UL-listed for Rigid-IMC conduit ensures cross-border compliance, making it suitable for Canadian and US facilities where durable, code-compliant conduit fittings are required.
H1033 carries UL certification for Rigid-IMC conduits and NEC/CEC compliance. This certification streamlines safety audits by confirming a vetted, code-aligned component, reducing the need for additional testing and documentation during regulatory reviews and project handoffs.
Using H1033 yields measurable ROI through reduced maintenance, lower replacement costs, and faster installations. The insulated, threaded design minimizes rework from insulation damage, while UL/NEC/CEC compliance reduces audit risk. Its compact size and standard 1" trade size simplify stocking and field deployment across multiple sites.
