Oatey 15420 Thread Sealant 0.5 Pint with Brush Gray

Product Description

The OATEY 15420 is a gray thread sealant compound designed for sealing threaded pipe joints in plumbing and mechanical systems. Supplied in a 0.5-pint screw cap can with an integrated brush applicator, it applies directly to male and female threads to fill voids and prevent leaks under pressure. The brush-top format reduces mess and speeds up application on the job. Licensed plumbers and pipefitters typically reach for a sealant like this when joining iron, steel, copper, brass, or plastic threaded fittings in gas, water, or steam service lines.

This thread sealant is suited for residential and light commercial plumbing installations where threaded connections require a reliable, pressure-resistant seal. Common applications include water supply lines, gas distribution piping, and steam systems. The compact 0.5-pint container is practical for service calls and small-to-medium installation projects where a full quart would be excessive. The gray color blends with common pipe and fitting finishes, making finished joints look clean and professional.

Key Features

• Gray formulation suits iron, steel, and mixed-metal threaded assemblies
• 0.5-pint volume is well-suited for service and repair work

Compatibility

Installation Notes

Thread sealant is applied by licensed plumbers or pipefitters working on pressurized piping systems. Shut off and depressurize the line before disassembling any existing joint. Apply sealant to clean, dry male threads before assembly; follow applicable local plumbing code and IFGC requirements for approved compounds on gas piping. Do not apply excess compound that could break free and enter the system interior.
