Brass Needle Valves

Straight and angled needle valves for precision valve control


If you are looking for more precise valves for controlling your water distribution application, we have them! When you need to have a more precise resistance to flow in your non-viscous system, a needle valve just might be the solution. Designed for use in fine control of many mediums, a needle valve offers a way to control flow in very small amounts, so you get the results you need with little effort. We are pleased to offer these and many other valves for water control applications.

The needle valves on this page feature:
  • Uniquely designed to provide fine flow adjustments for precise control
  • Frequently used in conjunction with coolers, instrumentation, hydraulic, and pneumatic systems
  • Compact and durable, these valves get the job done without taking up much space
  • Available with a wide variety of connection configurations to fit your application
  • Designed for maximum working pressure of 150 psi
  • Includes steel handles and metal-to-metal seats with fine-thread screw down
  • Not designed for natural gas, LPG, nuclear, or aircraft applications
  • Please note: handle style may vary

Angled Brass Needle Valves

Compression x Mips Angled Needle Valves

These valves are often used for providing water to evaporative (swamp) coolers. The 1/8" mips inlet will thread directly into evaporative water cooler hose bibbs found on our hose bibb page. They can also be used to provide and control water to drinking fountains, icemakers, decorative garden fountains, patio misters, humidifiers, and many other applications requiring flow adjustment.

Kit includes 1/4" OD brass sleeve for copper tube installation to outlet and 1/4" OD plastic delrin sleeve and brass insert for plastic tube installation to outlet.

Frequently Asked Questions

Q. "I'm hearing a lot about lead-free these days. What does that have to do with plumbing products and how does the new lead-free legislation affect me?"
A. Basically, the laws implemented Jan. 1st, 2014 require plumbing products that come in contact with drinking water to be essentially lead free (less than 0.25% weighted average). For further information about how the law determines what is lead free, rules regarding which plumbing products must be lead free, and who these laws will affect, please visit our LEAD FREE Plumbing Information page.
