Industrial 4X829 In Line Check Valve Three Quarter Inch FPT

4X829 is a brass inline check valve with 3/4-inch female pipe-thread (FPT) connections, designed to be installed directly in a line to allow flow in one direction while preventing backflow. The valve’s brass body is rated for up to 450 psi maximum working pressure, providing durable performance in typical fluid-handling systems. As an inline check valve, it provides backflow protection in piping runs and can be connected to compatible 3/4" FPT fittings to integrate into existing lines. Suitable for inline installations in plumbing and light industrial applications where backflow prevention is required, the 4X829 delivers a simple, compact solution for one-way flow control.
