Link-Seal® LS-300-C4

The LINK-SEAL® LS-300-C4 for 1" pipes is a modular mechanical seal designed to create a watertight and airtight barrier for 1" pipes penetrating walls, ceilings, floors, or other structures. Engineered with EPDM rubber links, it offers superior resistance to water, chemicals, oils, and temperature extremes, ensuring reliable, long-term performance. Its modular design allows for easy installation, fitting both standard and irregular openings, while corrosion-resistant stainless steel hardware ensures durability in indoor, outdoor, and underground environments. When the bolts are tightened, the links compress uniformly to form a secure seal, protecting against leaks, vibration, and environmental damage. Compliant with industry standards, the LS-300-C4 is ideal for plumbing, HVAC, electrical conduit, fire protection systems, and utility infrastructure, providing a low-maintenance, efficient sealing solution for demanding applications.
