OVERVIEW

Harris 9103616 Technical Overview

The Harris 9103616 is a precision-engineered Inlet Nut and Nipple assembly designed to facilitate the connection between high-pressure gas cylinders and industrial pressure regulators or manifold systems. This specific component utilizes the CGA-580 standard connection, which is the designated Compressed Gas Association fitting for inert gases, including Argon, Nitrogen, and Helium. Adherence to CGA standards is critical in industrial environments to prevent the accidental cross-connection of incompatible gases, ensuring both operational safety and equipment integrity.

The assembly features a 2.5-inch long brass nipple, which provides necessary standoff distance from the cylinder valve, allowing for easy access to the regulator body and preventing interference with cylinder guards or handles. The nipple terminates in a 1/2" Male National Pipe Thread (MNPT), a widely used tapered thread standard that ensures a tight, pressure-resistant seal when installed into the inlet port of a compatible regulator or distribution block. The 1/2" NPT size is common in heavy-duty and high-flow gas equipment, making this part a versatile solution for various industrial applications.

Constructed from high-quality brass, the 9103616 offers excellent machinability and resistance to corrosion, which is essential for maintaining the integrity of the sealing surfaces over repeated cylinder changes. The nut is designed to withstand the torque required to seat the nipple firmly against the cylinder valve outlet, creating a metal-to-metal seal that minimizes the risk of gas leakage. This component is an essential spare part for maintenance departments and gas equipment repair facilities, allowing for the quick refurbishment of regulators with damaged inlet threads or rounded nuts.

In summary, the Harris 9103616 combines robust material selection with precise dimensional tolerances to deliver a reliable connection interface for inert gas service. It is suitable for use in welding, purging, and laboratory applications where a secure CGA-580 to 1/2" MNPT transition is required.

FAQ

The CGA-580 connection is the standard fitting for inert gases, including Argon, Nitrogen, and Helium. It is designed to prevent cross-connection with flammable or oxidizing gases.

The nipple features a 1/2" Male National Pipe Thread (MNPT) for connection to the regulator body or manifold.

No. Oxygen uses CGA-540 and Acetylene typically uses CGA-510 or CGA-300. CGA-580 is strictly for inert gases.

You should use Teflon tape or thread sealant on the 1/2" MNPT threads that screw into the regulator. Do NOT use tape on the CGA-580 bullnose that connects to the cylinder.

The assembly is manufactured from high-quality brass, which is the industry standard for non-corrosive gas service fittings.

The nipple is 2.5 inches long, providing standard clearance for most regulator configurations.

It will fit any regulator or manifold that accepts a 1/2" NPT male input and requires a CGA-580 gas service connection.

Yes, this is a complete assembly that includes both the inlet nut and the nipple.
