Asc Engineered Solutions 390033116 Grooved Mpt Adapter Nipple

Product Description

The ASC Engineered Solutions 390033116 is a grooved x male pipe thread (MPT) adapter nipple designed to transition between grooved-end piping systems and threaded pipe connections. Part of the Gruvlok 7081 series, this fitting provides a reliable mechanical joint at the grooved end and a standard MPT connection at the threaded end. Sized at 2 inches by 4 inches and constructed from ductile iron, it is built for the pressure and load demands of commercial and industrial piping systems. Pipefitters and mechanical contractors install this fitting when integrating grooved piping with threaded components in fire protection, HVAC, or process piping applications.

This adapter nipple is suited for commercial mechanical systems where grooved piping infrastructure meets threaded equipment connections or branch takeoffs. The 2-inch grooved inlet accommodates standard grooved couplings, while the 4-inch overall length provides working clearance in tight mechanical spaces. It is commonly installed in wet and dry systems across commercial buildings, industrial facilities, and mechanical rooms where ductile iron fittings are specified for durability and code compliance.

Key Features

• Ductile iron construction for strength and corrosion resistance in demanding piping environments
• Grooved inlet end accepts standard grooved couplings for fast, tool-assisted assembly
• MPT outlet end provides compatibility with threaded pipe, valves, and equipment connections
• 2-inch by 4-inch sizing provides a practical transition length for mechanical installations
• Part of the Gruvlok 7081 series, designed to consistent dimensional standards

Compatibility

Designed as an OEM-style grooved x MPT adapter fitting for use in 2-inch grooved piping systems requiring a threaded male outlet connection.

Installation Notes

Installation should be performed by a licensed pipefitter or mechanical contractor in accordance with applicable mechanical codes. Shut off and depressurize the piping system completely before disassembly or fitting installation. The grooved end requires a compatible grooved coupling and gasket seated correctly before tightening. Apply appropriate thread sealant to the MPT end per manufacturer and code requirements before making up the threaded connection.
