TPU Gasket for Pressure & Vacuum Gauges – Flexible

This model is a flexible TPU gasket designed as a universal replacement seal for a wide range of pressure gauges and vacuum gauges, commonly used in pneumatic, hydraulic, and workshop applications.

The gasket fits many gauges that use a flat sealing surface and a central mounting passage. Thanks to the elasticity of TPU, it compensates for minor surface irregularities, absorbs vibration, and provides reliable sealing without cracking or permanent deformation.

It is especially useful when the original gasket is worn, damaged, or missing. The model is optimized for FDM 3D printing, does not require supports, and prints quickly with minimal material usage.
