Eaton 6815 Straight Needle Valve 1/4 Inch Mnpt Brass 150 Psi

Product Description

The EATON 6815 is a straight-pattern needle valve designed for precise flow control in plumbing, HVAC, and light industrial fluid systems. It features a 1/4-inch pipe size with male NPT connections on both ends and a brass body construction that resists corrosion in water and compatible fluid applications. Rated to 150 psi maximum working pressure, this valve provides reliable shutoff and throttling capability in compact installations. The overall length of 1.71 inches keeps the assembly footprint small. Licensed plumbers and HVAC technicians commonly install this type of valve in instrument lines, gauge connections, and low-pressure service applications where fine flow adjustment is required.

The EATON 6815 is suited for residential and light commercial applications where a compact, straight-pattern needle valve is needed at a 1/4-inch pipe size. Typical installations include gauge isolation, instrument manifold connections, and branch takeoffs in low-pressure plumbing and HVAC systems. The MNPT x MNPT end configuration allows direct thread engagement into female-threaded fittings or ports on both sides of the valve without additional adapters.

Installation Notes

Installation should be performed by a licensed plumber or qualified HVAC technician in accordance with applicable local plumbing codes and the IPC. Shut off system pressure and depressurize the line completely before removing or installing the valve. Apply thread sealant tape or compound rated for the service fluid to all male threads before engagement. Do not overtighten threaded connections in brass fittings, as this can crack the body or damage mating threads.
