Thomas & Betts 5266 Rubber Sealing Ring for 1-1/2" Liquidtight Conduit Fittings

The Thomas & Betts 5266 is a rubber sealing ring sized for 1-1/2" liquidtight conduit fittings, engineered to provide a dependable seal at the connection point between liquidtight flexible conduit and its fitting. Molded from durable rubber, this sealing ring is built to withstand the flexing, vibration, and moisture exposure that liquidtight conduit systems commonly encounter in commercial and industrial settings. Paired with the compression nut and body of a compatible 1-1/2" liquidtight fitting, the 5266 sealing ring helps keep moisture, dust, and debris out of the conduit connection so wiring stays protected. Electrical contractors rely on correctly sized sealing rings like this one to preserve the integrity of liquidtight conduit runs feeding motors, pumps, HVAC equipment, and other machinery. This 1-1/2" sealing ring is designed as a direct-fit replacement part for maintaining sealing performance on existing liquidtight conduit installations that already use compatible fittings of the same size.

Key Features

  • Trade Size: Sized for 1-1/2" liquidtight conduit fittings, ensuring the sealing ring seats correctly at the connection point.
  • Durable Rubber Construction: Molded from rubber for flexible, long-wearing performance that maintains its seal through installation and ongoing service.
  • Reinforced Sealing Design: Incorporates a steel component that helps the ring hold its shape and maintain consistent compression against the fitting body and conduit jacket.
  • Compression Sealing Function: Compresses between the liquidtight fitting body and gland nut to form a barrier against moisture, dust, and debris at the conduit connection.
  • Replacement-Ready Design: Sized to match 1-1/2" liquidtight fittings, making it a straightforward replacement part when a sealing ring wears out or is damaged during installation.
  • Fitting Compatibility: Designed to seat properly with 1-1/2" liquidtight fittings, supporting straightforward field replacement without reworking the connection.

Technical Specifications

  • Refer to manufacturer documentation for complete technical specifications.

Typical Applications

  • Liquidtight Flexible Conduit Connections
  • Outdoor and Wet-Location Electrical Equipment
  • Motor, Pump, and HVAC Equipment Wiring

Thomas & Betts TB5266 – Frequently Asked Questions

1) What trade sizes does the Thomas & Betts 5268 liquidtight sealing gasket come in?
Two trade sizes are offered: the 5266 for 1-1/2 inch liquidtight fittings and the 5268 for 2-1/2 inch. The sealing ring has to match the trade size of the fitting it seats in, so order by the fitting size stamped on the connector body, not by the conduit's inside diameter.
2) Can I replace just the sealing ring instead of the whole liquidtight connector?
Yes, provided the fitting body and gland nut are undamaged. The Thomas & Betts sealing ring is a direct-fit replacement part sized to existing liquidtight fittings of the same trade size, so a worn or torn ring can be swapped in the field without reworking the connection. If the gland nut threads are stripped or the body is cracked, replace the connector.
3) Will a 2-1/2 inch liquidtight sealing gasket work on a 2 inch fitting?
No. A 2-1/2 inch ring will not seat correctly in a 2 inch connector and the joint will leak. Thomas & Betts offers this gasket in 1-1/2 inch (5266) and 2-1/2 inch (5268); for other trade sizes you need the ring matched to that size fitting.
4) Does buying this sealing ring get me a complete liquidtight connector?
No. This is the sealing ring only, the gasket component that sits inside a liquidtight fitting. You still need the fitting body and gland nut, plus the liquidtight flexible conduit itself. Buy the ring when you are servicing a connection that already has a compatible fitting of the same trade size.
5) Where does the sealing ring actually go in a liquidtight conduit fitting?
It compresses between the liquidtight fitting body and the gland (compression) nut, sealing against the conduit jacket at the connection point. Tightening the gland nut squeezes the ring and forms the barrier that keeps moisture, dust, and debris from entering the conduit.
6) Is this sealing ring suitable for outdoor and wet-location equipment connections?
Yes. The gasket is intended for liquidtight flexible conduit connections in wet and outdoor locations, including motor, pump, and HVAC equipment wiring, and it is built to take the flexing, vibration, and moisture exposure those runs see. Wet-location rating comes from the fitting and conduit assembly as a whole, so the ring has to be correctly sized and the gland nut fully tightened.
7) What is the Thomas & Betts 5266 part number for, and how is it different from the 5268?
Both are liquidtight conduit sealing rings of the same design; the only difference is trade size. The 5266 fits 1-1/2 inch liquidtight fittings and the 5268 fits 2-1/2 inch. For stocking purposes, the 5266 carries UPC 786210052663 and the 5268 carries UPC 786210052687.
