SSPF Series Stainless Steel Push Fit fittings are versatile and reliable, designed for use with copper, CPVC, PEX, PE-RT & HDPE piping in plumbing and hydronic heating systems. Approved for behind-the-wall installations with or without access panels, and underground applications (with proper wrapping to prevent corrosion). These fittings are ideal for potable and non-potable water use. They eliminate the need for soldering, crimping, or solvent welding, making them perfect for repairs in wet, hazardous, or hard-to-reach locations where open flames pose a fire risk. The fittings come complete with stiffeners for PEX piping, which can be removed for copper installations. Additionally, the fittings are reusable and easily disassembled using the plastic disconnect tool.
