950510 - ESAB 1/4 NPTF to 3/16 Hose Barb Adapter

Precision Brass Connection for Industrial Gas Systems

The ESAB 950510 Hex Nipple is a critical component for professionals maintaining or assembling gas distribution systems in welding and industrial environments. Manufactured to ESAB's rigorous standards, this fitting is designed to provide a secure and leak-proof transition between threaded ports and flexible tubing. The unit features a 1/4" NPTF (National Pipe Taper Fuel) thread on one end and a barbed connection sized for 3/16" Inner Diameter (I.D.) hose on the other.

Constructed from high-quality brass, this nipple offers excellent resistance to corrosion and oxidation, a vital characteristic when dealing with various shielding gases or compressed air. The brass material is also spark-resistant, adding a layer of safety in volatile work areas. The "Hex" designation refers to the hexagonal section of the body, which allows technicians to apply torque using a standard wrench, ensuring the fitting is seated firmly without damaging the threads or the equipment port.

The use of NPTF threads is significant; unlike standard NPT, NPTF threads are designed to crush the crests and roots of the threads together when tightened, creating a mechanical seal that often requires little to no sealant tape (though use of approved sealant is still common practice for gas). This makes the ESAB 950510 an excellent choice for high-pressure or critical gas flow applications where leaks cannot be tolerated. Whether you are plumbing a new welding cell, repairing a regulator connection, or setting up a custom manifold, this adapter provides the reliability required for continuous industrial operation.

This fitting is compatible with a wide range of gases typically used in welding, including Argon, CO2, Helium, and Oxygen (ensure proper cleaning for Oxygen service if required). Its robust barb design ensures that once the hose is pushed on and clamped, it remains secure even under pressure fluctuations.
