Pro-source BD1493-1 Rtv Silicone Sealant 8 Oz Black

Product Description

The PRO-SOURCE BD1493-1 is an 8 oz black RTV silicone sealant formulated for sealing, bonding, and gasketing applications in mechanical and HVAC service work. RTV (room-temperature vulcanizing) silicone cures fully within 24 hours at ambient conditions, forming a flexible, durable seal that resists vibration, moisture, and temperature cycling. The low VOC content makes it suitable for use in environments with ventilation restrictions or compliance requirements. This sealant is packaged in a single 8 oz container and is commonly applied by HVAC technicians, plumbers, and mechanical contractors during equipment installation and repair.

This product is used across residential and light commercial applications where a reliable, flexible sealant is required. Typical uses include sealing duct joints, forming gaskets on compressor housings, sealing around pipe penetrations, and securing covers on electrical and mechanical enclosures. The black color blends with common metal surfaces in mechanical rooms and equipment cabinets. Its RTV chemistry makes it compatible with metal, glass, and most cured plastics encountered in trade work.

Key Features

• RTV silicone chemistry vulcanizes at room temperature with no heat required
• 24-hour full cure time for complete bond and seal development
• Black color suitable for metal, duct, and enclosure applications
• Low VOC content for use in regulated or low-ventilation environments
• 8 oz container size appropriate for single-job or service-call use

Compatibility

Designed as a general-purpose RTV silicone sealant for use on metal, glass, and compatible plastic substrates in HVAC, plumbing, and mechanical service applications.

Installation Notes

Apply to clean, dry, and oil-free surfaces for best adhesion. A licensed HVAC technician or mechanical contractor should verify that silicone sealants are appropriate for the specific joint or gasket surface before application. Allow the full 24-hour cure time before subjecting the joint to pressure, fluid exposure, or mechanical load. Follow all local codes and manufacturer equipment guidelines when using sealants on gas-side or refrigerant-side components.
