Liquidtight Flexible Metallic Conduit · 3/8 inch Sealtite · CST037

What this product is for

This product is a 3/8 in trade size liquid-tight flexible metal conduit used to protect and route conductors where a flexible raceway is needed. It is typically selected for equipment connections, machinery, control panels, and other installations where vibration, movement, or offset alignment make rigid conduit difficult to use.

Use for

• Machine and equipment connections
• Industrial and commercial wiring in wet or oily areas
• Tight routing where a smaller bend radius is helpful
• Outdoor or washdown-adjacent runs when installed with compatible liquid-tight connectors and in accordance with code

Avoid for

• Applications requiring a rigid raceway for physical protection
• Installations where the exact certification, temperature rating, or conduit type must be confirmed but project documents only reference the SKU
• Direct specification work without verifying the matching fittings, approvals, and jacket type

Best for

Best for electricians and maintenance teams needing a flexible metallic raceway with a black outer jacket for short equipment whips, machinery, and retrofit work. A 3/8 in trade size is commonly chosen for smaller conductor bundles and control wiring, but actual fill depends on conductor size, insulation type, and local electrical code.

Installed in

Typically installed in industrial plants, commercial facilities, OEM equipment, mechanical rooms, and service areas. Common installations include motors, pumps, HVAC equipment, and machine tools where movement or vibration is present.

Why this product exists

Liquid-tight flexible metal conduit provides a practical middle ground between rigid metal raceway and non-metallic flex. The metallic core helps with mechanical protection and flexibility, while the outer jacket helps resist moisture, oil, and general industrial exposure depending on the exact construction and approvals of the matched product.

Compared with similar products

Compared with rigid conduit, this product is faster to route around equipment and offsets. Compared with non-metallic liquid-tight conduit, a metallic core version is commonly selected where a metal raceway is preferred for equipment connections or where added crush resistance is desired. Exact performance, approvals, and temperature range should be verified against the manufacturer listing for CST037 before project release.
