The PRO-SOURCE 2556314899PRO is an angled miniature needle valve designed for precise flow control in low-volume fluid and gas line applications. Built with a nickel-plated brass body and a nitrile butadiene rubber (NBR) seal, this valve handles working pressures up to 145 psi and operating temperatures from 0 degrees F to 160 degrees F. The angled body configuration suits installations where inline access is restricted or a directional port orientation simplifies the plumbing layout. With universal thread type and a 1/4 x 1/8 inch pipe size, this valve fits a wide range of miniature flow-control applications in HVAC, refrigeration, pneumatic, and fluid-handling systems.
This valve is suited for residential and light commercial applications where compact size and accurate manual flow adjustment are required. The miniature form factor makes it practical for tight panel or manifold installations. Plumbers, HVAC technicians, and fluid-system technicians typically install this valve in instrument lines, pilot lines, bypass circuits, and low-pressure control systems. The NBR seal material is compatible with water, air, and many petroleum-based fluids, broadening its range of serviceable applications.
Designed as an OEM-style replacement or drop-in addition for miniature needle valve applications with 1/4 x 1/8 inch pipe connections using universal thread, suitable for low-pressure fluid and pneumatic control circuits.
Installation is typically performed by a licensed plumber, HVAC technician, or fluid-systems technician. Shut off and depressurize the line completely before removing or installing any valve. Apply appropriate thread sealant or PTFE tape to male threads per system requirements and local plumbing codes. Do not exceed the 145 psi rated working pressure or the 160 degrees F maximum temperature limit for the installed seal material.
