SJOOW vs SJTW: SJOOW wins for sunlight durability
SJOOW uses thermoset rubber (neoprene or EPDM) that resists UV and heat, while SJTW’s PVC jacket degrades and cracks in direct sun within months. SJOOW is heavier and stiffer but lasts years longer outdoors. For indoor or shaded use, SJTW is cheaper and fine.
