Abb EYS1-TB Sealing Fitting 1/2 Inch Vertical Conduit

Product Description

The ABB EYS1-TB is a 1/2-inch EYS drain sealing fitting designed for use in hazardous location conduit systems. The body is constructed of ductile iron, the plug is gray iron, and the nipple is steel, making this a robust fitting suited for demanding industrial and commercial electrical installations. It is rated for vertical mounting only. Electricians and industrial maintenance technicians install this fitting to seal conduit runs and prevent the passage of gases, vapors, and flames through conduit in classified hazardous areas.

This fitting is used in vertical conduit installations in Class I hazardous locations such as petrochemical facilities, refineries, wastewater treatment plants, grain handling facilities, and similar industrial environments where explosive or flammable atmospheres may be present. The vertical-only orientation is a critical installation requirement. The 1/2-inch trade size makes it appropriate for standard small-diameter conduit runs feeding instruments, junction boxes, and similar equipment in these environments.

Key Features

• 1/2-inch trade size for standard small-diameter conduit systems
• Ductile iron body for strength and corrosion resistance in industrial settings
• Gray iron plug provides a secure, durable seal
• Steel nipple for reliable conduit connection
• Vertical mounting orientation only — not rated for horizontal installation

Compatibility

Designed as an OEM-style EYS drain sealing fitting for vertical conduit installations in hazardous location electrical systems using 1/2-inch trade size conduit.

Installation Notes

Installation must be performed by a licensed electrician familiar with NEC Article 501 requirements for hazardous location conduit sealing. De-energize all circuits before beginning conduit work. This fitting is rated for vertical orientation only and must not be installed horizontally. Follow the sealing compound manufacturer instructions and all applicable local electrical codes.
