From powertrain integrity to emissions control, gaskets are the unsung guardians of engine performance. These essential components form the seal between moving and static parts—preventing leakage of fluids and gases in internal combustion engines (ICE), transmissions, exhausts, and more.

With the automotive industry in flux, gaskets are undergoing their own transformation. According to Stratview Research, the automotive gaskets market size was US$ 2.8 billion in 2024 and is likely to grow at a CAGR of 0.7% in the long run to reach US$ 3.0 billion in 2031, with emerging markets and electrification trends reshaping product demand and design.

Key factors behind the growth:

• Tightening emission standards are pushing OEMs toward more efficient engine designs, which in turn require higher-quality gaskets.

• Lightweighting efforts have triggered the replacement of traditional metal gaskets with advanced elastomeric and composite alternatives.

• Expanding vehicle parc in Asia-Pacific and Latin America is driving replacement demand in the aftermarket segment.

Despite the looming EV transition, ICE vehicles still dominate the global fleet, and their long tail in developing economies ensures a sustained gasket demand. Moreover, hybrid vehicles still rely on ICE subsystems, further supporting gasket relevance.

Gasket manufacturers are also investing in multi-layer steel (MLS), fiber-reinforced, and high-temp rubber materials, each engineered for precise application conditions. From head gaskets that withstand combustion chamber heat to oil pan gaskets that manage thermal cycling—material science is now as crucial as mechanical fit.

In a future where both ICE and electrified drivetrains will coexist for years, gaskets will remain fundamental. And as Stratview notes, the ones that adapt—both in material and form—will hold the seal on future mobility.
