Bard 1904-109 is an OEM red high temperature silicone sealant supplied in a 3.0 oz tube, commonly used during service or installation to seal and protect joints, penetrations, and small gaps around HVAC components where elevated temperatures and vibration can break down ordinary sealants. This Bard-approved RTV style silicone helps maintain a tight cabinet and air path seal to reduce nuisance air leakage and moisture intrusion that can lead to corrosion, airflow issues, or control compartment contamination. It is a practical consumable to keep on hand for Bard wall mount repairs and field retrofits when you need a dependable, heat-resistant seal that matches typical HVAC service practices.
