Also known as Pressure Class 125 flanges, these are for use in low-pressure applications. Bolt two same-size flanges together with a gasket (sold separately) to create an access point within a line. Flanges are aluminum, which is lightweight with good corrosion resistance.
Slip-on-Weld Fitting Connection — Slip-on weld flanges have no internal stop; slide a pipe through the flange and weld on both sides.
