Link-Seal® LS-300-C10

The LINK-SEAL® LS-300-C10 for 4" pipes is a modular mechanical seal designed to provide a watertight and airtight barrier for pipes penetrating walls, ceilings, and floors. Ideal for plumbing, HVAC, fire protection, and electrical conduit installations, this seal uses EPDM rubber links that resist water, chemicals, and temperature fluctuations, ensuring long-lasting durability. When tightened, the links compress uniformly around the pipe and opening, forming a secure, leak-free seal. Its corrosion-resistant stainless-steel hardware makes it suitable for both indoor and outdoor applications, including underground installations. This easy-to-install, code-compliant solution reduces labor costs by eliminating the need for caulks or sealants, making it a reliable choice for industrial, commercial, and residential projects.
