The Fig 7089 di-electric nipple inhibits the formation of galvanic corrosion between dissimilar piping metals. The di-electric nipples offer a variety of connections from thread to thread, thread to groove, or groove to groove all for IPS pipe sizes. The di-electric fittings are designed to meet ASTM F 492 for continuous use at temperatures from -40˚F to 230˚F (-40˚C to 110˚C) and pressures up to 300 psi (20.7 bar). The di-electric pipe connections will achieve a dielectric waterway in potable water and appropriate HVAC applications.
