Boss Products 142333 White Butyl Rubber Caulk 10.3 Oz

Product Description

The BOSS PRODUCTS 142333 is a white butyl rubber caulk in a standard 10.3 oz cartridge. Butyl rubber sealants are known for their strong adhesion, flexibility, and resistance to moisture and weathering, making them a dependable choice for sealing joints and gaps in HVAC, plumbing, and general construction applications. This product dispenses through a standard caulk gun and delivers a durable, flexible bead that remains pliable after cure. It is suited for use by HVAC technicians, plumbers, and general contractors who need a reliable sealant for metal, masonry, and other common substrate combinations.

Butyl rubber caulk in this format is commonly used in residential and light commercial settings for sealing duct joints, flashing penetrations, pipe chase openings, and exterior envelope gaps. The white color makes it appropriate for visible seams where a clean, finished appearance is required. It is equally suited for interior or exterior applications where a moisture-resistant, long-lasting seal is needed.
