Description & Features

The Brass Inline Easy Read Needle Valve Female 1/8-27 NPT Ports Up to 4.50 GPM & 2000.00 PSI offers precise control of flow with color coding and numerical readout ensuring accurate and repeatable settings. Designed for pneumatic systems and lower pressure hydraulic systems this valve is constructed from durable brass for reliable performance.

Featuring a metal knob and stem the valve can be finely adjusted within a small fraction of a turn providing meticulous control over fluid flow. The needle is constructed from brass while Viton o-rings and Teflon washer seals are standard components further enhancing durability and sealing effectiveness.

The valve supports a maximum operating pressure of 2000 PSI and a rated flow of up to 4.50 GPM with flow adjustments possible even under pressure. The female 1/8-27 NPT ports ensure compatibility with standard fittings while the locking set screw maintains settings securely.

Temperature resistance ranges from -15F to 400F making it suitable for various operational environments. The combination of robust construction and precise adjustment capabilities makes this needle valve an essential component in controlled fluid flow applications.

Product Questions & Answers (3)

Question by: Tommy R on Jan 10, 2026, 7:51 PM
does this valve work for pneumatic lines or is it strictly for hydraulic setups?
Answer by: Customer Support on Jan 12, 2026, 7:50 AM
Both, actually. Brass construction makes it the right call for pneumatic systems and lower pressure hydraulic applications. Just keep in mind the pressure ceiling is 2000 PSI, so if you're running a high-pressure hydraulic circuit, you'd want to look at a steel valve instead. For air lines and lighter hydraulic work it'll do the job well.
Question by: Cheryl C on Apr 27, 2025, 6:36 AM
Can this handle adjustments while it's under pressure?
Answer by: Customer Support on Apr 28, 2025, 6:56 PM
Controlled flow adjustments can indeed be made even when this needle valve is under pressure.
Question by: Ray B on Mar 16, 2026, 10:58 AM
trying to dial in a slow drip, how fine can you tweak this thing without it jumping all over the place
Answer by: Customer Support on Mar 18, 2026, 6:20 AM
With the easy read knob you can make very small adjustments, down to a fraction of a turn, and the color coding with the numeric readout helps you come back to the same setting again. It also has a locking set screw so the adjustment stays put once you get it where you want it.
