Overview
The Western Enterprises 15-4SF is a precision-engineered regulator inlet nipple assembly combining durable brass construction with an integrated particulate filter. Designed for welding, soldering, and industrial gas control systems, this nipple provides a fast, semi-permanent connection between gas regulators and cylinders while protecting sensitive regulator internals from contamination.
Key Features
- Integrated Filter: Built-in filter prevents particulates and moisture from entering regulator mechanisms, extending equipment lifespan and maintaining gas purity.
- Brass Construction: High-resistance brass body ensures durability, corrosion resistance, and long service life in industrial environments.
- Multi-CGA Compatibility: Compatible with CGA-500, CGA-510, CGA-580, and CGA-590 standards for versatile gas service applications.
- 1/4″ NPT Thread: Industry-standard NPT threading enables reliable, leak-free connections across regulators and hose assemblies.
- Lightweight and Compact: Weighs only 0.22 lb with compact dimensions for easy installation and replacement in tight spaces.
