FOR SOLVENT CEMENT CONNECTIONS: The Plastic Pipe Joiner connects solvent cement joints on all pipe schedules, IPS, and water pipe from 4in - 12in. For solvent cement connections, individually sized saddles must be ordered together with the Plastic Pipe Joiner (PPJ) and the plastic pipe joiner fitting attachment (PPJFA). PPJFA is only used for branch attachments. Solvent cement joining occurs at places such as processing plants, water treatment facilities and industrial locations, among other applications. NOTE: Connection saddles for gasketed pipe (PPJVS) or solvent cement connections (Plastic Pipe Joiners Saddles) - PPJ MUST BE PURCHASED SEPARATELY
