For applications that prohibit use of hot-dipped galvanized pipe and fittings, Wil-loc Black Weld-Ons and O-Rings may be specially plated or coated to fit your needs. Epoxy-painted, zinc-plated and fused-Teflon coatings are available.
Before welding, check to make sure locking ring can slide over the O.D. of your pipe. If not, place locking ring over the pipe and weld the male fitting onto the end of the pipe.
