Asc Engineered Solutions 390060119 Fig 7305 Grooved Coupling 3 in

Product Description

The ASC ENGINEERED SOLUTIONS 390060119 is a Gruvlok FIG 7305 grooved coupling designed for joining 3-inch HDPE pipe in mechanical piping systems. Constructed from ductile iron with a rust-inhibiting orange painted finish, this coupling delivers reliable joint integrity across a wide operating temperature range of -30 to 230 degrees F. The 6.75-inch overall length accommodates standard grooved pipe ends, and the included Grade E green EPDM gasket provides a secure, leak-resistant seal. Installation hardware ships with the coupling, including four zinc electroplated bolts, heavy hex nuts, and zinc-coated hardened steel washers. Licensed plumbers and pipefitters install this fitting in commercial and industrial HDPE piping applications.

The FIG 7305 coupling is intended for use with HDPE pipe in mechanical piping systems where grooved-end connections are specified. Its grooved end style simplifies field assembly compared to flanged or threaded alternatives, making it well suited for new construction and retrofit installations in industrial, municipal, and commercial mechanical systems. The 3-inch nominal size fits pipe with a 3.5-inch outside diameter. All hardware needed for assembly is included in the box.

Key Features

• Ductile iron body with rust-inhibiting orange painted finish for corrosion resistance
• Grooved end style for fast, tool-efficient mechanical joint assembly
• Grade E green EPDM gasket rated for -30 to 230 degrees F service
• Ships complete with four zinc electroplated bolts, heavy hex nuts, and hardened steel washers
• Designed specifically for HDPE pipe applications
• 3.5-inch OD fitting profile with 4.625-inch width and 6.75-inch body length

Compatibility

Designed for use with 3-inch nominal HDPE pipe with grooved ends. The FIG 7305 series is specified for grooved mechanical piping systems where HDPE pipe is used.

Installation Notes

Installation should be performed by a licensed pipefitter or plumber familiar with grooved mechanical piping systems. Depressurize and drain the affected pipe section before disassembling or installing any coupling. Inspect the pipe groove profile to confirm it meets the dimensional requirements for this fitting series before assembly. Torque hardware evenly in a cross pattern per the manufacturer installation instructions to achieve proper gasket seating.
