A Trane SEL00376 Flange Sealant forms a tight barrier around flange connections to minimize fluid loss and maintain dependable performance in the climate-control assembly.
The flange sealant seals mating flange surfaces to prevent air, fluid or refrigerant leaks where a traditional gasket may not be used in a heating and cooling system. Its gasket-eliminating formula and cartridge delivery matter because they allow controlled application, consistent coverage and a durable seal that maintains proper assembly integrity under operating conditions.
The flange sealant may need to be replaced if the HVAC system shows leakage, reduced pressure retention or performance issues caused by failing seals at flange connections. Physical signs can include cracking, shrinking, separation or residue breakdown and environmental signs may include heat exposure, vibration, moisture or chemical contact that could weaken the seal over time.
