Parker V409F-12-8 Brass Truck Valve Flare X Mnptf

Product Description

The PARKER V409F-12-8 is a brass truck valve designed for refrigerant and compressed-gas service in mobile and stationary applications. It features a flare inlet connection paired with a male NPT fitting (MNPTF) outlet, providing a reliable transition between flare tubing and threaded pipe or hose assemblies. The valve body is constructed from brass for corrosion resistance and durability. Rated from -30 degrees F to 250 degrees F, this valve handles a wide range of operating temperatures suitable for HVAC, refrigeration, and transport refrigeration systems. Installation and service are typically performed by licensed HVAC-R technicians or refrigeration mechanics.

This valve is suited for truck, transport refrigeration, and commercial refrigeration applications where a flare-to-MNPTF shutoff is required. The 3/4 x 1/2 inch connection sizing makes it appropriate for medium-capacity refrigerant lines and compressed-gas plumbing found in mobile refrigeration units, rooftop HVAC systems on vehicles, or similar service environments. The round handle style allows for positive, tactile shutoff confirmation in tight installation spaces.

Key Features

• Brass body construction for corrosion resistance in refrigerant and gas service
• Flare x MNPTF end connections for direct flare-to-threaded-pipe transitions
• Round handle type for positive manual shutoff
• Wide temperature range: -30 degrees F to 250 degrees F
• 3/4 x 1/2 inch connection sizing for medium-capacity line applications

Compatibility

Designed as an OEM-style replacement or service valve for refrigeration and HVAC systems requiring a flare x MNPTF brass shutoff valve in 3/4 x 1/2 inch sizing.

Installation Notes

Installation should be performed by a licensed HVAC-R technician or qualified refrigeration mechanic. Recover and reclaim all refrigerant from the system before removing or replacing any valve in accordance with EPA Section 608 requirements. Ensure flare fittings are properly formed and seated before torquing to avoid leaks. Verify all thread and flare connections are leak-tested after installation before returning the system to service.
