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

The Hayward Check VLV 1LB 1/4 NPT x 3/8 COMP Hydrapure is a compact, chemically resistant check valve designed to maintain one‑directional flow in small‑diameter chemical feed and Hydrapure system lines. Its 1/4‑inch NPT threaded inlet provides a secure, leak‑tight connection, while the 3/8‑inch compression outlet allows for stable attachment to compatible tubing, making it well‑suited for tight equipment pads and precise dosing applications. The internal mechanism is engineered to open at roughly 1 pound of cracking pressure, offering dependable sealing when flow stops and smooth operation when flow resumes. Built from materials intended to withstand pool and spa chemical environments, it supports long‑term reliability with minimal maintenance. Because of its small size and simple construction, the estimated weight typically falls in the range of 0.1 to 0.2 pounds, keeping it lightweight and easy to integrate into compact plumbing assemblies.
