Buying Guide

Choose the right conduit type

Pick liquid-tight flexible conduit for exterior solar runs where moisture ingress and movement are concerns, or non-metallic PVC for fixed, protected routes

Match conduit diameter to cable fill

Confirm conductor bundle size and select a conduit ID that meets NEC fill guidelines plus room for pulling and future upgrades

Check fittings and connectors included

Kits with compatible straight and 90° fittings simplify transitions at junctions and equipment entries, reducing need for separate parts

Prioritize UV and weather resistance

For rooftop exposure choose conduits and connectors rated for prolonged UV and temperature cycles to avoid embrittlement and leaks

Consider length and kit configuration

Select kits or spool lengths that minimize seams and joints on long runs to reduce leak risk and labor for splicing
