Parker V408NTA-8-8 Brass Truck Valve Nta X Mnptf

Product Description

The PARKER V408NTA-8-8 is a brass truck valve designed for use in compressed air and fluid line applications found on commercial vehicles and mobile equipment. Featuring a tube NTA (non-threaded attachment) inlet and a male NPT fitting outlet, this valve provides a secure shutoff point in portable or vehicle-mounted pneumatic and hydraulic systems. The brass body offers reliable corrosion resistance, and the round handle allows straightforward manual operation. Rated for a temperature range of -30 degrees F to 250 degrees F, it handles the thermal cycling common in mobile and fleet service environments. This valve is a direct-fit component installed by fleet mechanics, mobile equipment technicians, and commercial vehicle service professionals.

The V408NTA-8-8 fits standard 1/2 inch pipe connections and is suited for mobile equipment, over-the-road trucks, and service vehicles where a compact inline shutoff valve is required. Its NTA tube by MNPTF end connection configuration makes it a practical choice for connecting tubing runs to threaded port fittings in compressed air brake systems and similar service lines. Individual packaging makes it easy to stock as a service replacement component.
