Midland Industries 62630B1 Barstock Hex Head Plug 1/8 in Mpt

Product Description

The MIDLAND INDUSTRIES 62630B1 is a barstock hex head plug designed to close off open pipe ends in threaded piping systems. Machined from 304 stainless steel, this fitting accepts a 1/8 inch male pipe thread (MPT) connection and is rated for a pressure class of 1000/3000 lb, making it suitable for demanding fluid and gas applications. The hex head design allows installation with standard wrenches. At 0.02 pounds, the 62630B1 is a compact, precision-machined fitting intended for use by licensed plumbers, pipefitters, and HVAC technicians working on high-pressure piping assemblies.

This plug is suited for residential and commercial piping applications where a threaded pipe port must be sealed off permanently or temporarily. Typical installations include capping unused outlets on manifolds, test ports, or branch connections in water, steam, oil, or gas distribution systems. The 1/8 inch MPT size is commonly encountered in instrumentation lines, low-volume branch connections, and control piping. The 304 stainless steel construction provides corrosion resistance appropriate for wet or chemically active service environments.

Key Features

• 304 stainless steel construction for corrosion resistance in wet and chemical service environments
• 1/8 inch MPT connection for direct engagement with standard female-threaded pipe ports
• 1000/3000 lb pressure class rating suitable for high-pressure piping systems
• Hex head design allows torque application with standard open-end or box wrenches
• Barstock machined construction provides consistent thread quality and dimensional accuracy
• Lightweight at 0.02 pounds, minimizing load on small-diameter branch connections

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1/8 inch female NPT threaded ports in 1000 lb and 3000 lb class stainless steel piping systems.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes such as the International Plumbing Code (IPC) or International Fuel Gas Code (IFGC). Depressurize and isolate the piping system completely before installing or removing any threaded plug. Apply an appropriate thread sealant or PTFE tape to the male threads before engagement. Do not overtighten, as barstock stainless fittings can gall if excessive force is applied.
