Dap 8641 Silicone Rubber Sealant 10.1 Fl-oz Clear

Product Description

The DAP 8641 is a silicone rubber-base sealant packaged in a 10.1 fl-oz tube, designed for sealing and weatherproofing applications across HVAC, plumbing, and general construction trades. Silicone-base formulations offer strong adhesion to metal, glass, ceramic, and most plastics, and remain flexible after cure — making them a standard choice for joints and penetrations that experience thermal movement or vibration. The clear finish blends into most finished surfaces without visible residue. This sealant is typically applied by licensed HVAC technicians, plumbers, and general contractors during system installation or service work.

This product is suited for residential and light commercial applications where a flexible, waterproof seal is required. Common uses include sealing duct penetrations, pipe entry points through walls or floors, HVAC equipment panels, plumbing fixtures, and exterior building envelope gaps. The clear silicone formulation is appropriate wherever a finished, low-profile appearance is needed alongside durable, long-term weatherproofing performance.

Installation Notes

Application is typically performed by licensed HVAC technicians, plumbers, or general contractors. Clean and dry the substrate thoroughly before applying sealant to ensure proper adhesion.
