Gasket Temperature Rating

Overview

Engineering reference data for Gasket Temperature Rating in material science and properties.

Key Formulas

Stress

$\sigma = \frac{F}{A}$

Force per unit area.

Strain

$\varepsilon = \frac{\Delta L}{L_0}$

Change in length per original length.

Hooke's Law

$\sigma = E \varepsilon$

Stress proportional to strain in elastic region.

Thermal Expansion

$\Delta L = \alpha L_0 \Delta T$

Length change due to temperature.

Variables

Symbol	Description	Unit
$\sigma$	Stress	Pa
$\varepsilon$	Strain	—
$E$	Young's modulus	Pa
$\alpha$	Thermal expansion coefficient	1/°C
$\Delta T$	Temperature change	°C

Gasket Material Temperature Ratings

The following table provides common temperature ratings for various gasket materials, which is critical for selecting the appropriate seal for specific operating conditions.

Selecting a gasket material outside its rated temperature range can lead to loss of elasticity, hardening, degradation, and ultimately, seal failure. The temperature ratings represent continuous operating limits; short-term excursions may be possible but will reduce service life.
