WES680-3SF - CGA-680 Brass Inlet Nipple with Filter, 1/4" NPT, 3" Length

High-Performance Brass Inlet Nipple for Industrial Gas Systems

The Western Enterprises WES680-3SF is a precision-engineered inlet nipple designed to facilitate secure and reliable connections between high-pressure gas cylinders and regulation equipment. Manufactured from high-quality brass, this component is essential for maintaining the integrity of gas distribution systems in industrial, laboratory, and welding environments. The nipple is specifically machined to accommodate CGA-680 connections, making it the standard choice for inert gases such as Argon, Nitrogen, and Helium in high-pressure cylinders (typically above 3000 PSIG). It is also compatible with CGA-695, CGA-702, and CGA-703 standards, offering versatility across various gas services including Hydrogen, Methane, and Air.

One of the critical features of the WES680-3SF is its integrated sintered filter. In high-pressure gas systems, even microscopic particulate matter can cause significant damage to regulator seats and diaphragms, leading to creep, leaks, or complete failure. The built-in filter effectively traps these contaminants before they enter the downstream equipment, thereby extending the operational lifespan of expensive regulators and manifolds. This proactive protection is vital for facilities that prioritize maintenance efficiency and equipment longevity.

Technically, the nipple features a 1/4" NPT male thread on the equipment side, a standard size that ensures compatibility with a vast array of manifold blocks, pigtails, and regulator bodies. The 3-inch overall length provides sufficient clearance for installation, allowing technicians to easily access the 7/8" hex section with a wrench without obstruction. Rated for pressures ranging from 3000 to 7500 PSIG, this component is robust enough to handle the rigorous demands of heavy industrial use while maintaining a leak-tight seal. Whether configuring a new gas manifold or replacing worn components during routine maintenance, the WES680-3SF offers the reliability and performance required by professional gas technicians.
