Seaflo Straight Non-Return Valve [INV1Z15001]

Versatile 1", 1-1/4" & 1-1/2" Stepped Hose Connection

The **Seaflo INV1Z15001** is a high-performance, in-line composite non-return valve (check valve) engineered specifically for marine, RV, and industrial plumbing applications. Its primary function is to prevent the backflow of water into the bilge or system when the pump is deactivated, ensuring your vessel stays drier and your pump operates more efficiently.

SERVICEABLE DESIGN: This valve features a unique threaded middle section that can be easily unscrewed, allowing for quick inspection, cleaning, and maintenance without removing the entire hose assembly.
