Parker SV404P-12-8 Brass Truck Valve 3/4x1/2 Hose Id Mnptf

Product Description

The PARKER SV404P-12-8 is a brass truck valve designed for fluid control in hose-line assemblies. It features a 3/4-inch hose ID inlet and a 1/2-inch male NPT (MNPTF) end connection, making it a compact inline shutoff for mobile equipment, truck-mounted systems, and similar service applications. The overall assembled length is 3.73 inches. Constructed from brass with a round handle, this valve delivers reliable manual shutoff across a working temperature range of -30 degrees F to 250 degrees F. Installation and service are typically handled by plumbing or fluid-power technicians working on mobile or stationary hose systems.

This valve is suited for truck-mounted fluid transfer systems, mobile service units, and hose-line assemblies where a durable brass inline shutoff is required. The 3/4-inch hose ID inlet connects directly to standard hose, while the 1/2-inch MNPTF outlet threads into common NPT fittings. Its temperature ratings make it appropriate for a range of liquid service duties encountered in fleet maintenance, fuel transfer, and general industrial hose circuits.

Installation Notes

Installation is typically performed by licensed plumbers or fluid-power technicians. Depressurize and drain the hose line fully before removing or installing any inline valve. Apply thread sealant or PTFE tape to MNPTF threads in accordance with applicable plumbing codes. Inspect hose ID connections for proper seating and verify no leaks before returning the system to service.
