Construction Details
Series 209FXL combines a lead-free brass solder connection with a steel Female IPS connection to provide a transition between different piping materials.
The union incorporates a nylon insulating component and EPDM sealing washer to electrically separate dissimilar metals and help reduce galvanic action within the connection.
For common sizes, ASC specifies a zinc-plated forged carbon steel nut and IPS connection. Larger configurations use construction appropriate to their size while maintaining the dielectric function of the union.
