is a 1-inch explosion-proof conduit sealing fitting designed for hazardous industrial environments where moisture management and gas containment are critical. As part of the EZD series, this fitting is specifically engineered for vertical installations, featuring an integrated drain and inspection cover to prevent "pressure pilling" and liquid accumulation within conduit systems. Technical Specifications & Build

is built for durability and extreme conditions, utilizing heavy-duty materials and protective finishes.

Material Composition: Constructed from Feraloy iron alloy and/or ductile iron, providing the high structural integrity required for explosion-proof ratings.

Corrosion Resistance: Standard units feature an electro-galvanized finish with an aluminum acrylic paint. For highly corrosive environments, variants like the Ocal EZD311-G offer a double-coated PVC finish. Dimensions & Weight: Hub Size: 1 inch. Weight: Approximately 3.9 lbs.

Overall Size: Roughly 4.94 inches in height and 3.88 inches in width. Key Features & Functional Benefits

The "new" or standard EZD series stands out due to its specialized maintenance and safety features:

Integrated Drain: Includes a built-in drain to continuously bleed off accumulated condensate, which is essential in preventing water from reaching electrical enclosures.

Inspection Cover: Features a removable cover that allows for easy inspection of the seal without dismantling the entire conduit run, significantly simplifying maintenance routines. The real-time clock combined with the counter functions

Pressure Management: Designed to prevent the passage of gases, vapors, or flames through the conduit system and to limit "pre-compression" or pressure pilling—a phenomenon where an explosion in one part of a system can cause higher pressures in another.

Safety Certifications: It is fully compliant with UL 886 (UL 1203) and CSA C22.2 standards, making it suitable for Class I, Groups C and D hazardous locations. Common Applications
