Watts LF3006 dielectric union coupling 2 in FIP 250 psi

SKU CH-RH6N-94FG6

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

  • Prevents galvanic corrosion with dielectric insulator
  • Handles 250 psi maximum operating pressure
  • Operates from 33 to 180 degrees F
  • Polysulfone insulator resists chemical degradation
  • NBR gasket ensures reliable sealing

2 in dielectric union for plumbing systems

The Watts LF3006 dielectric union coupling connects dissimilar metal piping to prevent galvanic corrosion. It features a 2 in female threaded inlet and a 2 in female threaded outlet with an overall length of 3 1/8 in. The insulator uses polysulfone while the gasket uses NBR material. This fitting suits residential and commercial water lines requiring dielectric separation.

Zinc plated malleable iron construction rated 250

The union body combines zinc plated galvanized malleable iron with a black malleable iron nut for durability. It handles a maximum operating pressure of 250 psi across a temperature range of 33 to 180 degrees F. Threaded connections install with standard pipe tools without special equipment. The materials resist typical water chemistry in closed loop or potable systems.

Sustained pressure and temperature cycling

Under continuous 250 psi operation the polysulfone insulator and NBR gasket maintain seal integrity through repeated thermal expansion cycles. The malleable iron components resist deformation at the upper temperature limit of 180 degrees F. Installers should verify compatibility with specific pipe schedules and local codes before assembly. This union is not intended for gas service or steam applications.

Questions about this item

How do I install the 2 in FIP dielectric union and which step is most often done incorrectly?

Thread the female iron pipe ends onto the prepared pipe threads using pipe sealant on the metal threads only, then tighten the malleable iron nut; the common error is applying sealant or tape to the polysulfone insulator or NBR gasket, which can prevent a proper seal.

What maintenance or replacement will the dielectric union need over time?

Inspect the NBR gasket periodically for hardening or cracking caused by temperature cycling between 33 and 180 degrees F, and replace the gasket if leakage appears; the polysulfone insulator and zinc-plated malleable iron bodies do not require routine replacement.

What is the first limit reached under sustained pressure and temperature use?

The 250 psi maximum operating pressure is the primary limit; exceeding it risks joint failure before the 180 degrees F temperature ceiling becomes a factor.
