Asc 390060721 Fig 7307 Hdpe Transition Coupling 3 in Grooved

Product Description

The ASC Engineered Solutions 390060721 is a FIG 7307 HDPE transition coupling designed to join grooved-end piping systems where HDPE pipe meets ductile iron, steel, or other rigid pipe materials. Built from ductile iron with a rust-inhibiting orange painted finish, this coupling measures 7 inches in length with a 3-1/2 inch outer diameter and accommodates 3-inch nominal pipe. An EPDM gasket provides a reliable, pressure-rated seal across a wide service temperature range of -30 to 230 degrees F. Licensed plumbers and pipefitters working on mechanical, industrial, or municipal piping systems are the primary installers of this fitting.

This transition coupling is suited for grooved piping installations in commercial and industrial applications where HDPE transitions to grooved metallic pipe are required. It is commonly used in water distribution, fire protection, and mechanical systems where thermal movement, vibration, or dissimilar pipe materials must be accommodated at a joint. The grooved end style allows for fast, tool-ready assembly without welding or threading. The 3-inch nominal size fits standard grooved-end pipe configurations in both aboveground and belowground service conditions.

Key Features

• FIG 7307 series HDPE transition coupling for grooved piping systems
• Ductile iron body with rust-inhibiting orange painted finish for corrosion resistance
• EPDM gasket rated for service temperatures from -30 to 230 degrees F
• Grooved end style for fast mechanical assembly without welding or threading
• 3-1/2 inch OD and 7 inch length suit standard 3-inch nominal grooved pipe
• Designed for transitions between HDPE and grooved metallic pipe materials

Compatibility

Designed as an OEM-style grooved transition coupling for 3-inch nominal piping systems using the FIG 7307 series configuration. Suitable for use where HDPE pipe connects to grooved ductile iron or steel pipe in commercial and industrial mechanical systems.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC or local mechanical code requirements. Depressurize and drain the piping system fully before removing or installing any coupling. Inspect the EPDM gasket for damage before assembly and ensure grooved pipe ends are clean and free of burrs before seating the coupling. Do not exceed the rated service temperature or pressure limits for the gasket material and fitting series.
