Understanding Operating Limits

The NA1081 documentation specifically distinguishes catalogue maximum limits from continuous operating parameters. A stated maximum pressure cannot automatically be combined with the maximum temperature. Material service curves and assembly limits must be evaluated together, taking into account process fluctuations and the residual bolt load available after relaxation.

How Does It Compare to BLUE-GARD 3000?

TEADIT NA1081 and Garlock BLUE-GARD 3000 are both compressed sheet materials containing aramid fibres and a nitrile binder, but their formulations and properties are not identical. Compare density, compressibility, recovery, creep relaxation, leakage tests, and relevant certifications. Selecting a material from a similar family is merely a preliminary engineering assessment.

Practical Guidelines for Replacement

Specify the required product and thickness, flange standard, gasket geometry, and target bolt torque, along with the process media and concentrations. Review the current TEADIT data sheet and operating restrictions. A difference in compressibility may require reviewing the installation and torque procedures, even if gasket dimensions remain identical.

To compare specifications: Garlock BLUE-GARD 3000 and KLINGER KLINGERSIL C-4400. While these grades share a common aramid/NBR material family, formulation, regulatory approvals, and pressure-temperature curves remain proprietary to each manufacturer.
