The NOMACO HDPERED1121 is a high-density polyethylene (HDPE) socket reducer designed to transition between pipe sizes in water service and plumbing distribution systems. This fitting connects a 1.5-inch socket to a 1-inch socket, allowing contractors and plumbers to step down pipe diameter where flow requirements change. HDPE construction provides resistance to corrosion, chemical exposure, and moisture, making this reducer suitable for both potable water and non-potable applications. Licensed plumbers and pipefitters are the primary installers of this type of fitting in residential and light commercial piping systems.
The HDPERED1121 is suited for water service lines, irrigation supply runs, and general plumbing distribution where a 1.5-inch to 1-inch reduction is required. The socket-style end connections are designed for heat fusion or solvent-based joining methods appropriate to HDPE fittings of this type. This fitting is commonly used in residential new construction, service replacement projects, and utility infrastructure work where HDPE piping is specified for its durability and long service life.
Designed as an OEM-style replacement and standard fitment for HDPE socket reducer applications requiring a 1.5-inch to 1-inch pipe size transition in plumbing and water service systems.
Installation should be performed by a licensed plumber familiar with HDPE piping systems and applicable IPC or local plumbing code requirements. Shut off and depressurize the water supply line before cutting into any existing piping. Follow the fitting manufacturer joining procedure for HDPE socket connections, whether heat fusion or compatible mechanical method. Do not overtighten mechanical connections or apply joining methods not rated for HDPE material.
