The PRO-SOURCE 2556314499PRO is an angled miniature needle valve designed for precise flow control in small-bore piping systems. Built with a nickel-plated brass body and a nitrile butadiene rubber (NBR) seal, it handles a maximum working pressure of 145 psi across a temperature range of 0 to 160 degrees F. The angled configuration allows installation in tight spaces where inline valves cannot be positioned. This valve is well-suited for HVAC, plumbing, and light industrial applications where accurate flow metering or shutoff is required. It ships as a single unit and is sized for 1/4 inch pipe with a universal thread type.
This valve is commonly installed in residential and light commercial systems where controlled fluid flow is needed in a compact footprint. Its angled body makes it a practical choice for instrument isolation, sample ports, bypass lines, and tubing manifold assemblies. The NBR seal provides compatibility with water, air, and many common hydraulic and refrigeration-adjacent fluids. HVAC technicians, plumbers, and pipefitters regularly specify miniature needle valves of this type for low-flow control points throughout mechanical systems.
Designed as an OEM-style replacement or new-installation miniature needle valve for 1/4 inch pipe systems operating within the rated pressure and temperature limits.
Installation should be performed by a licensed plumber, pipefitter, or qualified HVAC technician following applicable IPC or IFGC guidelines. Isolate and depressurize the system fully before removing or installing any valve. Do not exceed the 145 psi maximum working pressure rating or operate outside the 0 to 160 degrees F temperature range. Apply thread sealant or tape per the fitting manufacturer's guidance and verify for leaks after pressurizing the system.
