Link-Seal® LS-300-C8

The LINK-SEAL® LS-300-C8 for 3" pipes is a modular mechanical sealing system designed to provide a watertight and airtight barrier for 3" pipes penetrating walls, ceilings, floors, or other structural openings. Made with EPDM rubber links, it offers superior resistance to water, chemicals, oils, and temperature variations, ensuring reliable, long-term performance in both indoor and outdoor environments. The modular design allows for easy customization to fit standard or non-standard openings, while corrosion-resistant stainless steel hardware ensures durability, even in underground or harsh industrial applications. When the bolts are tightened, the rubber links compress evenly to form a secure, leak-free seal that prevents vibration, leaks, and environmental damage. The LS-300-C8 is fully compliant with industry standards, making it ideal for plumbing, HVAC systems, fire protection, electrical conduits, and utility infrastructure. This low-maintenance, efficient sealing solution helps reduce installation time and ensures long-lasting protection for critical systems.
