Oatey Company 30115 Boiler Leak Sealer Liquid

Product Description

The OATEY COMPANY 30115 is a liquid boiler leak sealer formulated to seal and repair cracks and leaks in steam and hot water heating systems. The liquid formula works without clogging hot water coils, controls, valves, or vents, making it safe for use in fully plumbed systems under normal operating conditions. Once applied, it forms a tough seal that expands and contracts with thermal cycling, maintaining integrity through repeated heat-up and cool-down cycles. The formula contains no petroleum distillates, produces no odors, requires no priming, and does not foam. Licensed plumbers and HVAC technicians working on residential and light commercial boiler systems are the primary installers.

This product is suited for steam boilers and hot water heating systems experiencing minor leaks or seeping cracks in the system circuit. It is added directly to the system water, eliminating the need to drain and disassemble components to address small leaks. Typical applications include residential hot water boilers, steam radiator systems, and any closed-loop heating circuit where a liquid-applied sealant is appropriate. The no-foam, no-clog design makes it compatible with systems that include zone valves, air vents, and indirect water heater coils.
