HART Industrial D-3131-8-V-316 2 in. FNPT Class 3000 316 Stainless Steel Threaded Union - Viton Seal, Dielectric Coating
The HART Industrial Class 3000 316 Stainless Steel Threaded Union with Dielectric Coating is engineered for high-performance in corrosive environments. Designed to prevent galvanic corrosion and electrolytic deterioration, this union features a thermo-baked epoxy polymer coating with over 600 volts/mil dielectric resistance. The flat face design ensures a turbulence-free connection, while the Viton O-ring provides excellent sealing and isolation. With precision machining and superior material versatility, this union is perfect for long-lasting, reliable service. Made in the USA.
Note: Dielectric Coating applied to union tailpiece
Features
