Description This swing pipe adds to complete your underground sprinkler heads applications throughout the hardscapes, terraces, plantings, and rough terrain. It fits with the Rain Birds' EZ pipe system, making the sprinkler life for durability and refraining from any damage. Additionally, this black elbow has a pipe thread of 3/4" x 3/4" (MNPT) connection, making it easy installation because of its twist-in barb insertion for a watertight seal pipe.
