B38;K Llc 154-007 Test Plug 1.5 in Galvanized Steel

Product Description

The B38;K LLC 154-007 is a 1.5-inch test plug designed for pressure testing and leak testing in plumbing drain, waste, and vent systems. Galvanized steel flanges provide corrosion resistance and mechanical strength, while the molded rubber gasket creates a reliable seal against pipe openings during test procedures. This plug is sized for 1.5-inch pipe applications and is sold individually. Plumbers and pipefitters install this fitting during rough-in inspections and system commissioning to temporarily seal and pressurize DWV lines.

This test plug is suited for residential and light commercial plumbing applications where 1.5-inch drain or vent lines require temporary sealing during pressure or air tests. It is commonly installed by licensed plumbers ahead of final inspection, providing a code-compliant means to verify system integrity before walls are closed or fixtures are connected. The combination of steel flanges and a rubber gasket allows the plug to seat firmly without tools in most standard pipe openings of the corresponding size.

Key Features

• Galvanized steel flanges resist corrosion in wet and damp plumbing environments
• Molded rubber gasket provides a positive seal for air and water pressure testing
• Sized for 1.5-inch pipe openings, a common drain and vent pipe dimension
• Compact form factor at approximately 2 inches in each dimension for easy handling in tight spaces
• Lightweight at 0.25 pounds, reducing fatigue during repeated test setups

Compatibility

Designed as an OEM-style replacement and standard test accessory for 1.5-inch residential and commercial DWV plumbing systems requiring temporary sealing during pressure testing.

Installation Notes

This test plug is installed by licensed plumbers during pressure and leak testing phases of DWV rough-in work. Shut off any water supply and relieve system pressure before inserting or removing the plug. Follow local plumbing codes, including IPC guidelines, for required test pressures and durations. Do not use this plug as a permanent pipe closure or under continuous flow conditions.
