Plenumline™ is an extremely resilient acid waste system, made from flame-retardant PVDF thermoplastic, designed for challenging conditions including highly restrictive return air plenum applications and high-temperature corrosive chemical waste situations. Plenumline mechanical joint acid waste systems easily displace costly and difficult-to-install glass and metal systems. With Plenumline, time-consuming methods associated with conventional heavy and brittle systems are replaced by a time proven mechanical joint system that takes only seconds to complete. Plenumline Mechanical Joint Loose Nut 1/8 Bends come in 1-1/2", 2", 3" and 4" sizes.
