PGKD Modular Link Seal | Polywater | Visual Install Indicator | Watertight & Gastight
PGKD Modular Link Seal | Polywater | Visual Install Indicator | Watertight & Gastight
The Polywater PGKD Modular Link Seal provides a watertight and gastight solution for sealing pipe or conduit penetrations through walls, floors, or casings. Featuring an integrated visual installation indicator, this seal confirms proper compression during install—no torque wrench or retightening required. Designed with stainless steel V4A (AISI 316L) components and available in EPDM or NBR materials, PGKD ensures long-term corrosion resistance and reliable performance across water, gas, sewer, and electrical applications. Rated to 5 bar (72.5 PSI), it provides proven protection against leakage and pressure loss.
