Caulks and Sealants

American Bolt offers a wide range of caulks and sealants for industrial and commercial environments. These materials seal gaps and joints to block water, air, dust, and other intrusions across surfaces like metal, concrete, glass, and masonry—helpful in HVAC systems, building envelopes, and machinery. Choose from flexible silicones for movement, polyurethane for concrete joints, acrylic for general use, and specialty fire-resistant or hybrid options for precise needs.
