PF-4-240B1B2 - Western Enterprises Flexible Pigtail, 1/4" NPT Swivel Ends

Technical Overview of the Western Enterprises PF-4-240B1B2 Pigtail

The Western Enterprises PF-4-240B1B2 is a specialized flexible pigtail assembly designed to facilitate secure and efficient connections within gas distribution systems. Engineered for reliability, this component is essential for coupling regulators, manifolds, and piping infrastructure where rigid connections are impractical or susceptible to vibration damage. The assembly features 1/4-inch National Pipe Taper (NPT) threads on both ends, a standard size for a wide array of industrial gas equipment, ensuring broad compatibility with existing setups.

A defining technical feature of this model is the inclusion of swivels on both termination points. In static piping assemblies, torque transfer during tightening can induce torsional stress on the hose element, potentially leading to premature failure or structural weakness. The dual swivel mechanism negates this issue by allowing the fittings to rotate independently of the hose body during installation. This ensures that the hose remains in its natural, relaxed state, maintaining its structural integrity and pressure-holding capability. The fittings are constructed from high-grade brass, offering excellent machinability for precise threading and superior resistance to corrosion and deformation under load.

This pigtail is particularly suited for manifold applications where alignment between the gas source and the distribution piping may not be perfect. The flexibility of the hose compensates for minor misalignments, reducing the mechanical load on the system's rigid components. Western Enterprises maintains strict quality control standards, ensuring that this pigtail meets the rigorous demands of industrial environments. Whether used for inert gases or general distribution tasks, the PF-4-240B1B2 provides a leak-proof, durable solution for professional gas management.
