This Shurflo internal check valve is rated for a maximum of 65 PSI and is built for RV plumbing water fill and inlet applications. It uses a threaded inlet connection paired with an NPT outlet, and its 2-port design keeps water flowing in one direction to protect your fresh water system.
Finished in black, it's a straightforward fitting-style component for anyone rebuilding or repairing a water fill inlet line.
Confirm your existing fitting's thread and port sizes match before installing as a replacement.
