  • Dimensions: Compact molded design with approximate length ~2-3/8" and spigot insertion depth suitable for solvent-cement joining.
  • Use & compatibility: Ideal for residential and commercial plumbing, irrigation, and retrofit work where a reduction from 2-1/2" to 3/4" is required.

Install by preparing the pipe ends per solvent‑cement manufacturer recommendations: clean, apply primer/cement to the socket, then insert spigot fully and allow recommended cure time before pressurizing. Verify part number 437-288 against your piping drawings and measure pipe O.D. if exact fit is critical. For potable-water installations, confirm local code approvals and NSF listings when required.
