Watts LF3004 dielectric union coupling 2 in FIP 250 psi

SKU CH-6MJM-ZWTJJ

Dielectric union coupling with malleable iron zinc-plated galvanized body, polysulfone insulator and NBR gasket rated 250 psi from 33 to 180 degrees F

  • Prevents galvanic corrosion with dielectric polysulfone insulator
  • Withstands 250 psi maximum operating pressure
  • Handles 33 to 180 degrees Fahrenheit temperature range
  • Secure NBR gasket ensures leak-resistant seal
  • Durable zinc-plated malleable iron construction

Watts LF3004 dielectric union

The Watts LF3004 is a 2-inch dielectric union coupling designed for plumbing systems that require separation of dissimilar metals to prevent galvanic corrosion. It suits installers and maintenance teams working on commercial or residential water lines where dielectric protection is specified.

FIP threaded connections and 3 1/8 in overall length

The coupling features female iron pipe threads on both ends and an overall length of 3 1/8 inches, allowing direct integration into existing threaded pipe runs without additional adapters. Its polysulfone insulator and NBR gasket isolate the malleable iron bodies, freeing the system from electrolytic degradation at the joint.

250 psi rating across 33 to 180 Degrees F

Rated for a maximum operating pressure of 250 psi, the union maintains its seal and dielectric function throughout a continuous service temperature range of 33 to 180 degrees F. The zinc-plated galvanized malleable iron construction resists external corrosion while the internal insulator withstands sustained thermal and pressure cycling without breakdown.
