Smart Gasket FDA USP Class VI Clamp Gasket

On a tri-clamp connection, the gasket does more than seal. Some versions add a function: filtering, regulating, measuring or validating, directly at the connection plane, with no add-on device on the line.

The Smart Gasket is an instrumented gasket with one to four internal passages for thermocouples or accessories. The probe measures the temperature in the flow path, at the gasket plane of an existing fitting, without a thermowell or add-on tapping. It is Rubber Fab’s first historical product.

Instrumented gasket for thermocouples, 1/2″ to 4″, 1 to 4 ports

Smart Gasket clamp gasket, an instrumented gasket with one to four internal ports for thermocouples or accessories. Fitted between two ferrules with the dedicated thermocouple clamp. Sizes from 1/2″ to 4″. 0.090″ ports, compatible with type T, K, J, L, N, R or S probes, long or short. USP Class VI and ADI Free compliant. Temporary or permanent measurement, without a thermowell or costly special fitting.

Measuring in the flow path, at the fitting, without a tapping

Temperature measurement is usually carried out on a dedicated tapping: tee, thermowell, probe, and the associated dead leg. The Smart Gasket moves the probe into the gasket. The thermocouple passes through the gasket and measures at the connection plane, without adding a single tapping to the line.

Each gasket has one to four 0.090-inch ports. One port for a simple measurement, several for thermal mapping or redundancy required during validation. It accepts short or long temperature probes, and a sampling device with a luer lock connection is available.

The Smart Gasket requires the matching Rubber Fab thermocouple clamp, drilled to allow the probes to pass through. Gasket and clamp form a set: holes, ports and number of probes must match. Measurement can be temporary, for a qualification, or permanent in operation.

Dimensions and correspondence

The gasket is fitted like a standard gasket, on the outside diameter of the ferrule face. The clamp, ferrule and tube correspondence table, common to all versions, is available for download.

The gasket: the sensitive link in the clamp fitting

The quality of a clamp connection depends on three elements: the gasket, the clamp and pipe alignment. A version with an added function, screen, orifice or measurement port, places more stress on the gasket than a solid gasket. A stressed installation or excessive tightening damages it more quickly. Compression is achieved at the torque specified for the clamp, never by feel.

Frequently asked questions

Is it ordered with the clamp?

Yes. The Smart Gasket requires the dedicated thermocouple clamp, drilled for the probes. Clamp holes, gasket ports and number of probes must match. Gasket and clamp form an inseparable set.

How many ports should I choose?

One for a simple measurement, several for thermal mapping at the same point or for validation redundancy. The number of ports is fixed during manufacture; it cannot be added afterwards.

Which type of thermocouple?

The gasket accepts types T, K, J, L, N, R and S, in long or short probe versions. The type is chosen according to the temperature range and the reading instrument. Specify the type when ordering.
