Asc Engineered Solutions 2D.NP Square Head Plug 2.5 in Mnpt

Product Description

The ASC Engineered Solutions 2D.NP is a cored regular square head plug designed for threaded pipe systems in plumbing, mechanical, and industrial piping applications. Manufactured from cast iron with a galvanized finish, this plug features a male NPT (MNPT) end style and carries a 125 lb pressure rating. At 2.5 inches nominal size, it is built to seal pipe openings securely while resisting corrosion in exposed or damp environments. Domestic manufacture supports traceability requirements on commercial and institutional projects where material origin documentation is required.

This square head plug is suited for use in low-pressure steam, water, and general piping systems found in residential, commercial, and light industrial installations. The cored design reduces material weight while maintaining structural integrity under rated pressure. The galvanized cast iron construction makes it appropriate for wet or corrosive environments where bare iron would be unsuitable. Plumbers and pipefitters install this fitting during rough-in and system capping work.

Key Features

• Cast iron construction with galvanized finish for corrosion resistance
• 2.5-inch nominal size with male NPT thread engagement
• 125 lb pressure class rating suitable for low-pressure steam and water systems
• Cored regular square head design for standard wrench engagement
• Domestic manufacture supports project specification and material traceability requirements

Compatibility

Designed as an OEM-style replacement or standard fitting for 2.5-inch MNPT threaded pipe connections in 125 lb class cast iron piping systems.

Installation Notes

Installation is performed by licensed plumbers or pipefitters using a pipe wrench sized for the square head. Shut off and depressurize the system completely before removing or installing any threaded plug. Apply appropriate thread sealant or PTFE tape to the male threads before engagement. Work must comply with applicable local plumbing codes and ASME B16.14 standards for threaded pipe plugs.
