The male needle valve for pneumatic tubing regulates compressed-air flow to actuators, instruments and panels: the tapered stem closes the passage gradually with each turn. Push-to-connect port for 6, 8 and 10 mm metric tubing and male thread from 1/8" to 1/2"; 11 combinations in the lot.
| Feature | Specification |
|---|---|
| Function | Fine flow regulation by tapered (needle) stem |
| Tube connection | Push-to-connect for calibrated tubing of 6, 8 and 10 mm outside diameter |
| Male thread | Taper thread; manufacturers of the type offer NPT per ASME B1.20.1-2013 (R2018) or BSPT per ISO 7-1 — confirm the lot thread when quoting |
| Lot sizes | 6 mm × 1/8", 1/4", 3/8" · 8 mm × 1/8", 1/4", 3/8", 1/2" · 10 mm × 1/8", 1/4", 3/8", 1/2" (11 combinations) |
| Fluid | Filtered compressed air for instrumentation and automation |

We dispatch male needle valves for tubing to Bogotá, Medellín, Cali, Barranquilla and all of Colombia. Request a quote via WhatsApp with tubing diameter, thread size, working pressure and quantity to confirm availability and price.
It precisely regulates air flow to an actuator or instrument: the tapered stem reduces the passage gradually with each turn, allowing cylinder speeds and response times to be adjusted. It does not replace a quick shutoff valve.
With two data points: the tubing outside diameter (6, 8 or 10 mm) for the push-to-connect port, and the male thread size of the equipment or manifold (1/8", 1/4", 3/8" or 1/2"). The thread standard (NPT or BSPT) is confirmed when quoting.
It is designed for filtered compressed air in pneumatic and instrumentation service. For vacuum, inert gases or other fluids, pressure, temperature and seal compatibility must be validated against the manufacturer catalog before purchasing.
The price is per unit and depends on the tubing-thread combination (11 lot options) and quantity. TECTUL quotes via WhatsApp with the exact size and working pressure.

The dimensions, thicknesses, pressures, temperatures and other characteristics stated in this data sheet are theoretical nominal reference values, compiled from publicly available technical sources: international standards (ASME, ASTM, API, MSS, ISO and NTC, depending on the product) and published engineering literature. They are average approximations intended to guide selection, not a certificate of conformity for any given lot.
Actual values may vary due to conditions inherent to the manufacturing process — dimensional and wall-thickness tolerances (in pipe, typically ±12.5%), surface finish and residual stresses from forming or welding — and to factors inherent to the raw material — chemical composition variations within the ranges allowed by the standard, inclusions or heat-to-heat differences. They may also be affected by in-service events not foreseeable at design time: water hammer, vibration, thermal and mechanical fatigue, corrosion and operating overpressures, which can cause the element to fail before its estimated service life.
To know the certified behavior of a specific lot, TECTUL supplies upon request the manufacturer's mill test certificate (MTC) issued per the product standard; for critical applications, laboratory testing of the lot can also be arranged. In the absence of such certification, the data provided here must not be used as the sole criterion in critical or safety applications, or wherever the integrity of the line may compromise the lives of people or property; in such cases, consult our technical team first.
