Buying Guide

Choose liquid-tight conduit for wet locations

Liquid-tight non-metallic conduit prevents water ingress around connections and is appropriate for outdoor hot tub wiring runs near splashing or moisture

Match conduit size to cable and bend radius

Select a diameter (for example 1/2" vs 1-1/2") that comfortably accommodates the hot tub feeder conductors and maintains the required bending radius to avoid conductor damage

Check material and UV resistance

Non-metallic conduits resist corrosion and are lighter than metal; confirm the kit’s UV rating or use UV-protected conduit for exposed outdoor runs

Inspect fittings and sealing method

Verify the kit includes compatible liquid-tight fittings and glands that compress to form a watertight seal at equipment and junction boxes

Consider ratings and code compliance

Use conduits rated for wet locations and compliant with NEC requirements for spa and pool equipment wiring, and consult local code or an electrician for amperage and protection specifics
