Asc Engineered Solutions 1D.BP Square Head Plug 1-1/2 in

Product Description

The ASC Engineered Solutions 1D.BP is a cored regular square head plug designed for use in threaded pipe systems where a removable closure is needed. Rated at 125 lb, this plug features a male NPT (MNPT) end style and a 1-1/2 inch nominal size. Cast iron construction with a black finish makes it suitable for general-purpose industrial and commercial piping applications. Licensed plumbers and pipefitters install this type of plug to cap or temporarily close off threaded pipe ends during system installation, testing, or future service access.

This square head plug is used in low-pressure piping systems across commercial and light industrial settings, including HVAC hydronic systems, steam distribution, and general plumbing pipe assemblies. The cored design and square head allow for easy installation and removal using a standard pipe wrench or socket. At a 125 lb pressure class, it is suited for moderate-service applications where a secure, removable threaded closure is required.
