Electri-flex 29105 Liquidtight Flexible Metal Conduit 4 in

Product Description

The ELECTRI-FLEX 29105 is a Type LA liquidtight flexible metal conduit designed to protect electrical wiring in wet, oily, and dry environments where rigid conduit cannot accommodate movement or vibration. Constructed from hot-dipped galvanized steel with a gray PVC jacket, it provides a continuous 100-foot length suitable for larger commercial and industrial wiring runs. The 4-inch trade size conduit features an inside diameter ranging from 4 to 4.04 inches and an outside diameter ranging from 4.46 to 4.5 inches. A 12-inch minimum bend radius keeps installation manageable in tight routing conditions. Licensed electricians and electrical contractors install this conduit in applications requiring moisture and oil resistance.

Type LA liquidtight flexible metal conduit is used in commercial and industrial settings where electrical runs must tolerate exposure to liquids, cutting oils, or coolants. Common install scenarios include machine tool connections, pump wiring, HVAC equipment hookups, and any final connection where the conduit must flex or absorb vibration between a rigid raceway and a piece of equipment. The 4-inch trade size accommodates larger conductor bundles typical of high-ampacity service runs in manufacturing, processing, and heavy commercial facilities.

Key Features

• Type LA liquidtight construction provides resistance to water, oil, and moisture ingress
• Hot-dipped galvanized steel core delivers mechanical protection and durability
• Gray PVC outer jacket rated for dry, wet, and oil-exposed environments
• 4-inch trade size with inside diameter of 4 to 4.04 inches accommodates large conductor bundles
• 12-inch minimum bend radius supports routing through constrained spaces
• Full 100-foot coil length reduces splicing needs on longer runs

Compatibility

Designed as an OEM-style replacement and standard-fit liquidtight flexible metal conduit for 4-inch trade size liquidtight fittings and connectors used in commercial and industrial electrical installations.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NEC Article 350 governing liquidtight flexible metal conduit. De-energize all circuits before beginning work and verify lockout/tagout procedures are followed. Use fittings rated for Type LA liquidtight conduit to maintain the moisture and oil seal at termination points. Avoid exceeding the minimum bend radius to prevent jacket damage or conductor stress.
