Our Series SFS-NY Nylon Front and Back Ferrule Sets for Tube, crafted from durable 316SS with nylon components, are essential fittings used in hydraulic and instrumentation systems to create secure, leak-proof connections. Ferrules are small metal or plastic rings that grip the tubing and form a tight seal when installed with tube nuts. The front ferrule creates a secure seal against the tubing, while the back ferrule supports the tubing and prevents it from slipping. Nylon ferrules are particularly useful in applications where lightweight, corrosion-resistant, and non-conductive properties are necessary, such as in chemical processing, pharmaceuticals, and food-grade systems. These nylon ferrules offer a reliable and cost-effective solution for systems requiring high chemical resistance and minimal risk of corrosion. Proper installation ensures strong, leak-free connections in a wide variety of industries.
