Asc Engineered Solutions 390060762 Fig 7307 Coupling 8 in

Product Description

The ASC ENGINEERED SOLUTIONS 390060762 is a Gruvlok FIG 7307 HDPE Transition Coupling designed to connect grooved-end pipe to HDPE piping systems in demanding mechanical and industrial applications. Constructed from ductile iron with a rust-inhibiting orange painted finish, this coupling handles a temperature range of -30 to 230 degrees F and accommodates an 8-5/8 inch OD pipe. At 13-1/2 inches in length and 4-1/4 inches thick, it provides a robust, pressure-rated connection. Hardware is included: four 5/8 x 3-3/4 inch zinc electroplated bolts, zinc electroplated heavy hex nuts, zinc-coated hardened steel washers, and a Grade E green EPDM gasket. Licensed plumbers and pipefitters install this coupling in commercial, industrial, and municipal piping systems.

This coupling is sized for 8-inch nominal HDPE pipe and is intended for grooved-end transition connections. Typical applications include municipal water distribution, industrial process piping, and mechanical systems where HDPE pipe must interface with grooved ductile iron or compatible piping components. The included EPDM gasket is suited for water service and a wide range of fluid-handling applications within the rated temperature range. The FIG 7307 series is a recognized solution for HDPE transition work in both above-grade and below-grade installations.

Key Features

• Ductile iron body with rust-inhibiting orange painted finish for corrosion resistance
• Grade E green EPDM gasket rated for -30 to 230 degrees F service
• Grooved end style for fast, reliable mechanical pipe joining
• Fits 8-5/8 inch OD pipe at 8-inch nominal size
• Includes all hardware: zinc electroplated bolts, heavy hex nuts, and hardened steel washers
• Designed specifically for HDPE pipe transition connections

Compatibility

Designed for use with 8-inch nominal HDPE pipes featuring a grooved end style. Compatible with grooved piping systems where HDPE-to-ductile-iron transition couplings are required per the FIG 7307 series specification.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable mechanical and plumbing codes. Depressurize and isolate the piping system completely before beginning any coupling work. Verify that pipe ends are properly grooved to the correct specification before seating the EPDM gasket and torquing the included hardware. Do not exceed the coupling temperature and pressure ratings for the intended service conditions.
