Abb EYS3-TB 1 Inch Eys Drain Seal Sealing Fitting

Product Description

The ABB EYS3-TB is a 1 inch EYS-series drain seal sealing fitting designed for vertical-only installation in hazardous location conduit systems. The body is constructed from ductile iron, with a gray iron plug and steel nipple. This fitting creates a drain seal in electrical conduit runs, preventing the passage of gases, vapors, and flames through the conduit while allowing condensation to drain. It is installed by licensed electricians and industrial maintenance technicians in classified hazardous locations where explosion-proof conduit sealing is required by code.

The EYS3-TB is suited for 1 inch conduit in Class I hazardous location installations, including petrochemical, oil and gas, manufacturing, and industrial processing environments. The vertical-only orientation must be observed during installation to ensure proper drainage function. This fitting is a recognized component in explosion-proof conduit systems governed by NEC Article 500 requirements for sealing and drainage.

Installation Notes

Installation must be performed by a licensed electrician in accordance with NEC Article 500 and applicable local codes governing hazardous location wiring. De-energize and lock out all circuits before beginning conduit work. The EYS3-TB is rated for vertical installation only — do not install in horizontal or inverted positions. Verify conduit size and thread engagement before final assembly.
