Professional Applications & Engineering Value
This nickel-plated brass sealing nut delivers critical performance where fluid containment and pressure integrity are paramount. The silicone rubber seal maintains elasticity across extreme thermal cycles (-100° to 400° F), preventing brittle failure in cryogenic applications or degradation in high-heat environments. The UNF fine thread configuration with Class 2B thread fit ensures precise engagement with mating components, reducing the risk of cross-threading while providing superior resistance to vibration loosening. Engineered for industrial sealing applications including hydraulic systems, compressor assemblies, and processing equipment, this component solves leakage challenges in high-pressure scenarios up to 6000 psi while meeting rigorous UL 50 standards for enclosure integrity.
Specification Summary & Compliance
This sealing nut features precision 1/2"-20 UNF right-hand threads with Class 2B thread fit per ASME B1.1 standards, ensuring dimensional accuracy and reliable performance. The component meets UL 50 certification for environmental protection and is RoHS 3 (2015/863/EU) compliant with exemption 6(c) for lead in copper alloy, along with full REACH (EC 1907/2006) compliance regarding substance restrictions. Manufacturing adheres to inch system specifications with standard hex profile (3/4" width, 7/32" height) for consistent tool engagement across industrial applications.
