Couplings & Sleeves

Pipe Couplings, Restraint Couplings & Tapping Sleeves

Couplings and sleeves are what let you join, repair, and tap pipe in the field without re-cutting the whole run. This category pulls together the flexible, wide-tolerance couplings crews reach for on water and wastewater mains, the tapping sleeves that make live branch connections, and the threaded rod couplings that extend and join hanger supports overhead.

The heart of the lineup is Hymax, whose dynamic-restraint couplings handle a wide diameter tolerance in a single unit - joining dissimilar pipe materials and out-of-round pipe from roughly 4 inches on up, rated to 260 PSI with stainless steel hardware. We also stock Hymax fabricated tapping sleeves for hot-tapping live mains, plus Piers steel rod couplings for splicing and extending threaded hanger rod. Stainless construction throughout resists corrosion in buried and wet-location service.

Spec a coupling by pipe OD range, pressure rating, and whether the joint needs axial restraint against thrust - not just nominal pipe size. Match rod couplings to the thread size of your existing hangers.
