1/4 in. x 1/8 in. Male Flare x Male Needle Valve
1/4 in. x 1/8 in. Male Flare x Male Needle Valve
Overview
The Midland Industries 46028 is a brass needle valve with 1/4 in. Male Flare x 1/8 in. Male NPT connections in a straight (inline) pattern. Built for fine, repeatable flow metering, it pairs a SAE flared inlet with a male-threaded outlet so you can throttle low-flow lines in refrigeration, HVAC, and instrumentation service. The needle stem gives smooth, gradual control rather than abrupt on/off action.

Typical Applications
Needle valves are designed for fine flow metering and throttling where gradual, precise adjustment matters. The 46028 suits refrigeration and HVAC charging and metering lines, gauge and instrumentation hookups, and low-flow tubing where a flared tube end meets a male-threaded port. Its straight body keeps inlet and outlet inline for simple, compact plumbing.

Frequently Asked Questions
What is a needle valve used for?
A needle valve uses a fine tapered stem for precise, gradual control of low flow rates, ideal for metering, throttling, and instrumentation rather than fast on/off service.
What is a flare connection?
A flare end seals against a matching flared tube using a coned 45° (SAE) seat and nut, common in refrigeration and HVAC tubing; the other end here is male NPT pipe thread.
Flare vs. compression: which do I need?
Match your existing line. Flare requires a flared tube end and seals metal-to-metal; compression seals on plain tubing with a ferrule. Confirm before ordering.
Is this a straight or angled valve?
The 46028 is a straight inline pattern, keeping inlet and outlet on the same axis; a 90° version is offered separately for corner runs.
