This marine ball scupper valve provides efficient cockpit drainage while preventing seawater backflow. Made from durable PC, HDPE, and PVC, it offers excellent corrosion resistance, UV protection, and long service life in harsh marine environments.

The gravity-controlled ball design improves drainage, reduces clogging, and replaces aging rubber flapper valves, solving common issues such as backflow, blockage, and poor sealing.

Fits standard 1-1/8" boat drain fittings for quick installation and reliable performance.
ROQIFY provides durable marine solutions built for safety, reliability, and ease of use.
