JACO nylon fittings are engineered to deliver reliable, long-term performance across a wide range of fluid handling applications, offering excellent resistance to organic solvents, oils, and gasoline while maintaining structural integrity under demanding conditions. these fittings retain good mechanical strength at elevated temperatures and are suitable for both cold and hot water use, making them a versatile solution for residential, commercial, and light industrial systems; however, they are not recommended for exposure to ammonium, boric acid, calcium, sulfuric acid, or hydrochloric acid. Compared to traditional metal compression fittings, JACO nylon fittings provide significant advantages, including superior electrical insulating properties that prevent electrolytic corrosion caused by dissimilar metals, thereby extending tubing life and improving system reliability. The low density and inherent softness of the nylon material enable effective absorption of mechanical and acoustical vibrations, reducing noise transmission and minimizing stress on connected components. Additionally, the smooth internal surface of the fittings ensures low resistance to flow, supporting efficient fluid movement while helping to prevent scale buildup over time. The specified configuration features a 1/4" OD tube by 1/8" male pipe thread (MPT) connection, constructed from durable natural-colored nylon, and includes a ferrule nut with an integral sleeve designed specifically for use with soft plastic tubing. The ferrule nut incorporates a 7/16-20 thread size to ensure secure, leak-resistant assembly. Designed for a maximum operating pressure of 50 psi and a temperature range from -40°F to 200°F, JACO nylon fittings provide a dependable, corrosion-resistant, and cost-effective alternative to metal fittings in appropriate applications where chemical compatibility and performance requirements are met.
