OVERVIEW

Fine-Tune Your Flame

When you're on the job, having the right flame can make the difference between a clean cut and a messy slag pile. This Oxygen Needle Valve with B-Size Fittings gives you the control you need right at your fingertips. Built from heavy-duty brass, it’s tough enough to handle the knocks and drops of a busy shop or field site. If you need to restrict flow for a specific heating tip or add a shut-off point to your line without walking back to the cylinder, this is the tool for the job.

The valve features a knurled knob that is easy to grip and turn, even when you're wearing heavy welding gloves. The threading is the industry-standard 5/8"-18 Right Hand (B-Size), so it screws directly onto your oxygen hose, regulator outlet, or torch inlet without the need for extra adapters. It’s fully cleaned for oxygen service right out of the package, so you can hook it up and get to work safely.

Don't settle for inconsistent flow. This needle valve provides a smooth, linear adjustment that stays set where you put it. It's perfect for custom setups, repairing older equipment, or simply adding an extra layer of control to your oxy-fuel rig. Keep one in your toolbox for those times when precise gas management is the key to the project's success.

FAQ

This valve features B-Size connections, which are 5/8"-18 UNF threads.

Yes, it is cleaned for oxygen service and uses Right-Hand (RH) threads to prevent cross-connection with fuel gases.

No. Fuel gases typically use Left-Hand (LH) threads (notched nuts) to prevent accidents. This valve has Right-Hand threads specifically for oxygen or inert gases.

The valve body and internal components are machined from high-quality brass.

No, this is a needle valve designed for flow control (throttling). It does not regulate pressure; you still need a pressure regulator at the cylinder.

It is typically rated for standard oxy-fuel working pressures, usually up to 200 PSIG. It is not designed for high-pressure cylinder pressure (2000+ PSIG).

Yes, the knob is knurled to provide a good grip, making it easy to adjust while wearing welding gloves.

No, this is a standalone needle valve. Check valves or flash arrestors should be installed separately if required for your safety setup.
