8696 - B-Size Oxygen Male to 1/2 Inch NPT Male Brass Adapter

Connect Your Oxygen Gear with Confidence

When you are setting up a shop manifold, repairing a gas distribution line, or building a custom welding rig, having the right fittings is the difference between a job well done and a dangerous leak. The ESAB 8696 Adapter is the heavy-duty brass connector you need to bridge the gap between your standard oxygen equipment and industrial piping. If you have ever tried to hook a standard oxygen hose or regulator up to a 1/2-inch pipe drop and realized the threads don't match, this is the part that solves your problem instantly.

Built for the Shop Environment
Cheap fittings can crack, cross-thread, or corrode over time, leading to costly gas leaks and safety hazards. This ESAB adapter is machined from solid brass, giving it the durability to withstand the daily grind of a welding shop. Brass is the material of choice for oxygen fittings because it doesn't spark if you drop a wrench on it, and it holds up incredibly well against atmospheric corrosion. Whether you are plumbing a new station drop in your garage or maintaining a large industrial manifold, this fitting provides the professional reliability you expect from a brand like ESAB.

Seamless Compatibility
One end of this adapter features a B-Size Oxygen Male thread (the standard 9/16"-18 Right-Hand thread you see on almost all oxygen hoses and regulators). The other end sports a 1/2" NPT Male thread, which screws directly into standard iron or brass pipe fittings, ball valves, and wall outlets. This allows you to easily adapt a 1/2-inch pipe port to accept a standard oxygen hose or regulator. It's a simple, effective solution that eliminates the need for multiple bushings and potential leak points.

Safety First
Working with oxygen requires strict attention to cleanliness. Oil and grease can be catastrophic in an oxygen system. That is why this adapter comes cleaned for oxygen service right out of the package. You can install it with peace of mind, knowing it meets the safety standards required for welding gas applications. Just remember to use oxygen-safe Teflon tape or sealant on the NPT side to ensure a perfect, leak-free seal. Keep a few of these in your maintenance kit so you are never stuck waiting on parts when you need to get gas flowing.
