1/4 NPT Brass Needle Valve

This 1/4 inch NPT brass needle valve is rated for 600 psi and 300 degrees F, making it suitable for pneumatic flow control in compressed-air systems. The brass body and adjustment knob resist corrosion in typical shop environments. It is intended for technicians and maintenance staff who need precise metering of air or inert gas. The valve has a single controlled direction with matching inlet and outlet ports.

Threaded installation with sealant

The valve installs by threading the 1/4 NPT ports into matching fittings using pipe sealant or tape rated for 600 psi. Over-tightening can distort the brass body and cause leaks at the seat. Ensure the adjustment knob turns freely before pressurising the line. Misaligned piping is the most common cause of premature seat wear.

Verify pressure and temperature limits

Confirm that your system operates at or below 600 psi and 300 degrees F before ordering. The valve is not rated for higher pressures or for media that exceed the temperature limit. Check that 1/4 NPT threads match your existing fittings and that the flow direction matches the single controlled port. California Proposition 65 warnings apply to this product.

Questions about this item

How can I confirm the 600 psi needle valve is regulating flow correctly after installation?

Pressurise the line up to 600 psi and observe the brass adjustment knob; smooth, repeatable metering without leakage at the 1/4 in NPT ports shows the valve is working as intended.

What comes with the ZORO SELECT 5TUL2 needle valve and what must I supply?

The valve ships assembled with its brass body, brass adjustment knob and 1/4 in NPT inlet and outlet ports; you must provide compatible 1/4 in NPT fittings, thread sealant and the pneumatic tubing or piping for your circuit.

Which pressure-rated version should I choose for a 300 °F compressed-air line?

Select the 600 psi brass model — it carries a 600 psi maximum pressure rating and a 300 °F maximum temperature rating, matching your line’s pressure and temperature requirements.
