682P - Western Enterprises 682P CGA-350 Hand-Tight Inlet Nut for Hydrogen

Western Enterprises 682P CGA-350 Plastic Handwheel Inlet Nut

The Western Enterprises 682P is a specialized inlet nut designed to facilitate the connection of gas regulators and manifolds to compressed gas cylinders equipped with CGA-350 valves. This component is engineered primarily for use with Hydrogen, Methane, Natural Gas, and other flammable gas mixtures requiring the CGA-350 standard. The unit features a robust brass core that ensures thread durability and pressure containment, encased in or attached to a large, ergonomic plastic handwheel.

One of the primary technical benefits of the 682P is its hand-tightening capability. In many industrial and laboratory environments, gas cylinders must be replaced frequently. Standard brass nuts require a wrench for tightening and loosening, which can lead to downtime if tools are misplaced or result in rounded corners on the nut over time. The 682P eliminates these issues by providing sufficient leverage through its handwheel design to achieve a leak-tight seal against the cylinder valve nipple without the use of external tools. The plastic material is selected for its durability and grip, ensuring it can withstand the rigors of daily use.

Safety is paramount in high-pressure gas handling. The 682P adheres to the Compressed Gas Association (CGA) V-1 standards for the CGA-350 connection, utilizing a 0.825"-14 NGO Left-Hand thread. The left-hand thread is a critical safety feature used for fuel gases to prevent accidental cross-connection with oxygen or inert gas equipment (which typically use right-hand threads). Rated for pressures up to 3000 PSIG, this inlet nut maintains structural integrity under standard cylinder pressures, providing peace of mind for operators handling volatile gases like Hydrogen.

Western Enterprises is a leader in the manufacturing of compressed gas fittings, and the 682P exemplifies their commitment to quality and utility. Whether used in a welding shop, a research laboratory, or a manufacturing facility, this component ensures a reliable, efficient, and safe connection between the gas source and the regulation equipment.
