950556 - 1/8 Inch to 1/4 Inch NPT Brass Hex Adapter

Industrial Grade 1/8" to 1/4" NPT Hex Adapter

The ESAB 950556 Adapter is a high-quality brass fitting engineered for professional welding and industrial applications. Designed to facilitate the connection between 1/8-inch National Pipe Taper (NPT) and 1/4-inch NPT interfaces, this component is indispensable for technicians working with gas regulation equipment, piping systems, and custom fabrication setups. The NPT thread standard is widely used in North America for its ability to form a seal via the interference fit between the tapered threads, and this adapter is machined to strict tolerances to ensure compatibility and sealing performance.

Constructed from solid brass, this hex adapter offers superior mechanical properties compared to softer metals or plastics. Brass is the industry standard for oxygen and fuel gas service due to its non-sparking nature and resistance to oxidation. This makes the 950556 adapter a safe choice for environments where flammable gases are present. The material also withstands the temperature fluctuations and physical vibrations often encountered in welding shops and manufacturing plants, providing a long service life without degradation.

Key Installation Benefits:

• Hexagonal Profile: The hex body provides a flat surface for wrench engagement, allowing for precise tightening in tight spaces where a pipe wrench might not fit.
• Versatility: Ideal for stepping up or stepping down line sizes in pneumatic tools, gas manifolds, and fluid handling systems.
• Durability: Resistant to cross-threading and deformation under stress.

When installing this adapter, it is recommended to clean both male and female threads thoroughly to remove any debris or oil. Apply a high-quality thread sealant compatible with the gas or fluid being transported. For oxygen service, ensure that any sealant used is specifically rated for oxygen to prevent combustion hazards. Tighten the fitting securely using the hex grip, but avoid over-tightening, which can crack the female port or distort the threads. This ESAB adapter is a simple yet vital solution for maintaining the versatility and safety of your industrial gas equipment.
