The Zurn Wilkins One-Bolt Coupling saves approximately 80% of time over a two-bolt coupling, the company says. It secures with just one bolt, making it quick and easy to join grooved pipes in sprinkler and fire suppression systems. The rigid coupling provides sturdy, inflexible joints and features a three-tab gasket design for simple, leak-free installation. Constructed from ductile iron, the one-bolt coupling offers strength and durability. It features pre-lubricated, pressure-responsive EPDM gaskets, making it suitable for most outdoor environments. The One-bolt coupling is available in sizes ranging from 1-1/4” to 6”.
