Thomas & Betts EYS3-TB Drain Sealing Fitting

The Thomas & Betts EYS3-TB Drain Sealing Fitting is a 1-inch EYS sealing fitting used to seal conduit runs against vapors, flames, and gases in hazardous locations. It features a ductile iron body with a gray iron plug and a steel nipple and is listed for explosion‑proof and dust‑ignition‑proof service (UL 886, CSA C22.2) with vertical mounting compatible with IMC or rigid conduits. Catalog variants report finishes including an aluminum acrylic‑painted exterior on ductile iron or zinc‑plated constructions, reflecting different listings from Thomas & Betts/ABB. With a 2.4-inch turning radius, it supports installation in tight conduit runs while providing a robust sealing interface to prevent ignition sources from entering enclosures.
