The B&K 1/2 in. FPT X 1/2 in. FPT Galvanized Dielectric Union is a purpose-built connector designed to safely join two 1/2" female pipe threads while protecting your piping from galvanic corrosion. Built for durability in water service, this galvanized dielectric union helps you create reliable, long-lasting connections where different metals meet.
Key benefits that matter in real-world plumbing
-
Dielectric protection: The dielectric barrier between dissimilar metals prevents electrochemical corrosion, reducing the risk of leaks and extending the life of your piping network.
-
Robust galvanized body: Galvanized steel construction stands up to moisture and typical indoor/outdoor environments, giving you a sturdy, corrosion-resistant connection.
-
Two 1/2" FPT ends: Precisely matched for standard 1/2" female pipe threaded lines, making installation straightforward with common plumbing fittings.
-
Compact, space-friendly design: Thin profile and simple geometry help you fit this union in tight spaces, crawl spaces, basements, or utility rooms without bulky hardware.
-
Flow-friendly interior: Smooth bore minimizes disruption to water flow and helps maintain steady pressure through the connection.
Ideal uses and practical applications
- Integrating dielectric isolation when joining copper to galvanized or other metals in residential or light commercial water systems.
- Retrofits and upgrades where a reliable, corrosion-preventive connection is needed between lengths of pipe with different metal compositions.
- Appliance hookups or valve assemblies where maintaining material separation reduces corrosion risk and extends component life.
Simple installation tips
- Ensure both mating threads are clean and undamaged before assembly.
- Apply appropriate thread sealant or Teflon tape compatible with metal piping, following standard piping practices.
- Finger-tighten first, then snug with a wrench to avoid over-tightening that could damage the dielectric barrier.
- Inspect the connection after pressure is restored for any signs of leakage and re-tighten if necessary per code guidelines.
