Parker V409F-10-8 Brass Truck Valve Flare X Mnptf

Product Description

The PARKER V409F-10-8 is a brass truck valve designed for refrigerant and fluid service applications in mobile and stationary systems. It features a flare inlet by male NPT (MNPTF) end connection, making it a practical choice for connecting refrigerant lines to service ports and fittings. The body is machined from brass for corrosion resistance and durability under repeated use. Rated from -30 degrees F to 250 degrees F, this valve handles a broad temperature range suited to both refrigeration and air conditioning service work. The round handle provides positive manual control in tight access areas common to truck and transport refrigeration units.

This valve is commonly used in transport refrigeration, truck HVAC systems, and stationary refrigeration applications where a reliable manual shutoff or service valve is required at a flare-to-NPT transition point. The flare x MNPTF configuration suits field service technicians working with copper flare lines that terminate into NPT-threaded fittings or manifolds. The 5/8-inch flare by 1/2-inch pipe sizing fits standard refrigeration line sets in light commercial and transport cooling systems.

Key Features

• Brass body construction for corrosion resistance and long service life
• Flare x MNPTF end connections for direct flare-to-NPT installation
• Round handle for manual operation in restricted spaces
• Wide operating temperature range: -30 degrees F to 250 degrees F
• 3.47-inch overall length for compact inline installation
• 5/8-inch flare by 1/2-inch male NPT connection sizing

Compatibility

Designed as an OEM-style service valve for transport refrigeration and mobile HVAC systems requiring a flare x MNPTF shutoff or service point in standard 5/8-inch by 1/2-inch line configurations.

Installation Notes

Installation should be performed by a licensed HVAC or refrigeration technician. Recover all refrigerant from the system before removing or replacing any valve in the refrigerant circuit. Ensure flare connections are properly formed and free of burrs before torquing fittings to avoid leaks. Verify all NPT threads are sealed with an approved thread sealant rated for refrigerant service prior to system recharge.
