Hayward CHECK VLV 4LB 1/4NPT X 3/8COMPHYDRAPURE

The Hayward CHECK VLV 4LB 1/4NPT x 3/8 COMP Hydrapure is a compact, purpose‑built check valve designed to maintain one‑directional flow and protect Hydrapure systems from backflow that could compromise performance or water quality. Its 1/4‑inch NPT inlet and 3/8‑inch compression outlet make it suitable for tight plumbing runs, especially in chemical feed or metering applications where secure, leak‑resistant connections are essential. The valve is engineered to open at approximately 4 pounds of cracking pressure, ensuring stable operation even in low‑flow environments. Its small form factor keeps installation flexible, and components are typically built from corrosion‑resistant materials to withstand pool and spa chemical exposure. Given its size and construction, the estimated weight is roughly 0.1 to 0.2 pounds, making it easy to integrate into lightweight tubing assemblies without adding strain to fittings or mounts
