Customize your sprinkler system with Orbit's heavy-duty 1 in. female adapter. The Orbit manifold system is the easiest way to assemble a sprinkler valve manifold. Manifold fittings are durable and UV resistant. The innovative swivel feature allows you to easily tighten or remove manifold parts. Use the patent-pending swivel lock to increase torque while tightening adapters. The free-spinning swivel can then be used to tighten the manifold without causing misalignment.
