Asc Engineered Solutions 390060739 Fig 7307 Hdpe Coupling 4 in

Product Description

The ASC ENGINEERED SOLUTIONS 390060739 is a FIG 7307 series HDPE transition coupling designed to connect grooved-end HDPE pipe in mechanical piping systems. Constructed from ductile iron with a rust-inhibiting orange painted finish, this coupling handles a temperature range of -30 to 230 degrees F. It features an EPDM gasket and measures 8.25 inches in length with a 4.5-inch OD, making it a robust mechanical joining solution for 4-inch nominal pipe. Licensed plumbers and pipefitters install this fitting in commercial and industrial HDPE piping applications where grooved mechanical coupling is specified.

This coupling is engineered specifically for HDPE pipe systems requiring a grooved end connection style. It is suited for use in commercial mechanical systems, industrial process piping, and water distribution applications where HDPE-to-grooved-end transitions are required. The included hardware — four zinc electroplated bolts, heavy hex nuts, zinc-coated hardened steel washers, and a Grade E Green EPDM gasket — allows for a complete installation without sourcing additional fasteners.

Key Features

• Ductile iron body with rust-inhibiting orange painted finish for corrosion resistance in exposed environments
• EPDM gasket rated for -30 to 230 degrees F, suitable for a broad range of fluid and ambient temperatures
• Grooved end style compatible with standard mechanical coupling installation practices
• 4-inch nominal size with 4.5-inch OD and 8.25-inch overall length
• Includes all required hardware: zinc electroplated bolts and nuts, hardened steel washers, and Grade E EPDM gasket
• Designed specifically for HDPE pipe transition applications

Compatibility

Designed for use with 4-inch nominal HDPE pipes requiring a grooved end mechanical coupling transition. Verify pipe OD and groove dimensions against FIG 7307 specifications before installation.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local mechanical and plumbing codes. Power down or depressurize the system fully before disassembly or fitting installation. Ensure pipe ends are properly grooved to the correct specification before seating the gasket and coupling housing. Tighten bolts evenly in an alternating pattern to achieve uniform gasket compression without over-torquing.
