Hydraulic Unions

Magic Plastics is pleased to offer its patented Vibeproof Locking Union Technology created to prevent and avoid costly plumbing service calls. This technology incorporates a series of strategically placed scallops on the pump union nut and tailpiece so that hand-tightening of the nut will engage the lock, preventing the union from loosening or backing out during vibration to eliminate unnecessary service calls. Made from PVC or ABS and meets all ASTM standards and plumbing requirements, assemblies are available in a variety of configurations in 1”, 1½”, 2”, 2½” & 3” IPS sizes. Learn more here.
