Flex Torque

Flex Torque is the moment (ft.-lbs.) at break-a-way required to angularly displace a ball joint. Because of the relatively small size of Standard Series ball joints the flex torque does not vary significantly with pressure. The tabulated values are the design values from zero pressure through the rated pressure range.

Seal Descriptions and Pressure/Temperature Ratings

Seal Number 11

Compound 11 is a pressure molded proprietary seal compound recommended for general purpose applications for steam, hot water and oil systems. Compound 11 has the highest pressure/temperature ratings of the available seal materials.

Rated for service at temperatures from -50º F to +525º F.

Pressure/Temperature Ratings
Number 11 Composition Seal



Seal Number 23

Compound 23 is pressure molded Teflon®, a chemically inert material that is recommended for applications involving corrosive fluids. Compound 23 has the lowest flex torque of the available seals.

Rated for service at temperatures from
-325º F to +450º F.



Pressure/Temperature Ratings
Number 23 Teflon®Seals



Seal Number 24

Compound 24 is pressure molded proprietary compound of glass fiber and Teflon®. The addition of the glass fiber adds strength and stability to the seal. The compound is chemically inert and is recommended for applications involving corrosive fluids when a higher pressure rating is required.

Rated for service at temperatures from
-325º F to +425º F.
