The Torque Knob
The Torque Knob prevents over-compression by setting a Torque limit. The Torque Knob is an easy tool to use. With two sockets to choose from the Torque Knob fits all wing nuts. It can even be used for MHP clamps with hex bolts. Depending on the gasket material you can chose the specific Torque in Nm. Turn until it starts clicking. By using the Torque Knob you introduce consistency in your system. The clean ability increases dramatically because of less gasket intrusion in the flow path.

Over - Compression
Over-compression is the biggest problem experienced in this industry. Most of the elastomer gaskets are already destroyed even before they are being used. Think about the life expectancy of a gasket that is over-compressed.
The Torque Knob prevents over-compression because of its preset (and calibrated) torque limit. The Torque Knob is an easy tool to use. With two sockets to choose from the Torque Knob fits all Wing-Nuts. It can even be used for MHP clamps. Depending on the gasket material you can choose the specific torque in Nm. Place the knob and socket over the wing nut. Turn it clockwise, once it “clicks” you have reached the desired torque with a precision of 4%.
PTFE type gaskets require to “settle” this means that they need to be re-torqued after the first and sometimes second sterilization cycle. Re-torqueing is always done at the same torque level, not higher.
We recently introduced a re-calibration program. Torque Knobs with serial numbers can be returned to Ultrapharma for yearly calibration. An inspection will take place before calibration.
Check out our Snap-On gaskets that can provide a solution when excessive torque to close the connection is required due to misalignment.
