Liquidtight Straight Connector · 1-1/4 in Trade Size Nylon 6/6 Gray For Nonmetallic Liquidtight Tubing Topaz P474

SKU: TPZ-P474

Straight liquidtight connector for 1-1/4 in trade size nonmetallic liquidtight tubing. Nylon 6/6 body with gray finish, UL and CSA approvals, and a compact straight profile for wet or dry location conduit terminations.

What this product is for

This straight liquidtight connector is used to terminate 1-1/4 in nonmetallic liquidtight tubing to an enclosure or hub while helping maintain a secure, moisture-resistant connection. It is commonly selected for control panels, outdoor equipment connections, and commercial or industrial wiring where flexible liquidtight conduit is required.

Use for

Use for flexible nonmetallic liquidtight tubing in wet or dry locations, equipment connections subject to vibration, and transitions into boxes, cabinets, and enclosures. Suitable where a straight connector is preferred to keep the conduit run aligned with the entry point.

Avoid for

Avoid using this connector with metallic liquidtight conduit unless the conduit type and fitting listing match the installation. Do not use where a 90 degree fitting, grounding-style metallic fitting, or a different trade size is required.

Best for

Best for electricians and maintenance teams needing a nonmetallic liquidtight fitting that resists corrosion and suits damp, washdown, or outdoor-adjacent installations. Nylon construction is a practical choice where metal corrosion is a concern.

Installed in

Typically installed in commercial buildings, industrial equipment, rooftop units, pump connections, and service areas where flexible liquidtight tubing is brought into an enclosure. Typical selection depends on conduit type, entry size, and environmental exposure.

Why this product exists

This fitting provides a listed method to secure and terminate nonmetallic liquidtight tubing while helping protect the connection point from moisture and debris. It gives installers a straightforward straight-body option for larger 1-1/4 in conduit runs.

Compared with similar products

Compared with zinc or malleable iron liquidtight connectors, this nylon 6/6 version is lighter and better suited where corrosion resistance is a priority. Compared with 90 degree connectors, the straight body is typically chosen when there is enough clearance in front of the enclosure entry.
