Buying Guide
What matters most for rigid 3/4 conduit?
Material, code compliance, and environment drive your choice. PVC conduits offer excellent corrosion resistance and easier cutting for DIY tasks. Rigid non-metallic options are often lighter and cheaper, with good UV resistance for outdoor use. Metal straps and bodies deliver stronger physical protection for industrial settings.
Which conduit type fits outdoor or direct burial needs?
Choose UV-stabilized PVC RNC or liquid-tight conduits designed for direct burial. Look for ETL or UL listings and compatibility with burial conditions. For direct outdoor exposure, UV inhibitors and weather resistance are key.
How important are fittings and accessories?
Conduit kits with straight and 90-degree fittings save time and reduce leaks. Flexible conduits simplify routing in tight spaces but may require careful handling to avoid kinks. Rigid conduit bodies help with junctions and access points in complex layouts.
What installation considerations help avoid issues?
Plan bend radii, store lengths to minimize waste, and ensure solvent cement or fittings match the conduit material. For metal conduits, check corrosion protection, while for PVC, confirm solvent compatibility with seals and gaskets.
What is a practical decision framework?
- Indoor DIY projects: choose PVC rigid conduit for ease and insulation.
- Outdoor or coastal areas: UV-stable PVC or liquid-tight conduits.
- Complex routing: rigid conduit bodies and straps for robust installation.
