A U-shaped or forked component used to connect, support, or operate mechanical and plumbing equipment and systems.

Yoke (Plumbing/Mechanical) is a U-shaped or forked component used to connect, support, or operate mechanical and plumbing equipment and systems through specialized hardware that provides structural support, operational control, or connection interfaces while enabling proper equipment function and system integration. This essential mechanical component consists of a rigid frame or bracket with two parallel arms or branches that cradle, support, or connect equipment components while providing secure mounting, operational leverage, or connection points for pipes, valves, and mechanical devices. Yokes are critical in plumbing and mechanical systems where they provide equipment support, operational control, connection interfaces, and structural stability, making them indispensable for valve operations, pipe supports, equipment mounting, and any mechanical application where U-shaped or forked components are necessary for proper system function and equipment integration.

Yokes are utilized in various plumbing and mechanical applications including valve operations where they provide the structural framework for gate valves, globe valves, and other manually operated valves, pipe support systems where they cradle and support piping runs while allowing for thermal expansion, equipment mounting where they provide secure attachment points for pumps, motors, and mechanical devices, HVAC systems where they support ductwork, equipment, and control components, fire protection systems where they support sprinkler piping and equipment, and specialty applications including industrial processes, marine systems, and utility installations where robust support and connection components are required for system reliability and operational control. Each application requires appropriate yoke design, materials, and installation methods based on load requirements, environmental conditions, and operational needs.

Types and configurations of yokes in mechanical systems include valve yokes that provide the structural framework and threaded stem guide for manual valve operation, pipe support yokes that cradle piping while allowing movement and providing load distribution, equipment mounting yokes that secure pumps, motors, and other mechanical equipment to foundations or structures, adjustable yokes that accommodate different pipe sizes or equipment configurations, spring-loaded yokes that provide constant support while allowing thermal movement, and specialty yokes including seismic-resistant, corrosion-resistant, and high-temperature designs for specific applications. Yoke selection depends on application requirements, load conditions, and environmental factors.

Fun Fact: The term “yoke” comes from the agricultural tool used to harness oxen, and mechanical yokes have been used in plumbing systems since the 1800s, with modern valve yokes capable of operating under pressures exceeding 6,000 PSI.
