Fel-Pro® HTA Gaskets Handle Engine Heat

Inside the Problem – Rising Engine Temperatures

Once only found in performance vehicles, turbocharged engines can now be found in many passenger cars, trucks and SUVs on the road today. Both domestic and foreign nameplate manufacturers have turned to turbocharged engines as a way to downsize the engine to improve fuel economy with no decrease in performance. This power results in a hotter running engine, including higher exhaust temperatures.

Higher engine and exhaust temperatures make conventional gasket materials susceptible to failure due not only to extreme temperatures, but also to pressure and vibration. When a conventional gasket fails, the engine may create less power due to an exhaust leak. This can result in a decrease in acceleration and gas mileage. Conventional gaskets made with traditional materials and designs may not be up to the challenge of sealing the hotter engine environments.

The Solution – Fel-Pro® HTA Gaskets

Fel-Pro’s proprietary line of HTA (High Temperature Alloy) gaskets are engineered to handle today’s high output and hotter running engines. Fel-Pro’s innovative materials and application-specific designs deliver a reliable gasket solution specifically designed for the repair environment to help seal imperfect sealing surfaces. Fel-Pro’s HTA gaskets have gone through rigorous testing processes so you can install them with confidence.

Inside Fel-Pro HTA Gaskets

Designed to perform in high-heat environments, Fel-Pro’s HTA gaskets feature the right materials and technology to provide a reliable seal. Combining a patented super high temperature alloy material with a proprietary High Temperature Coating (HTC), Fel-Pro HTA gaskets are designed to handle the heat of today’s high output engines.

Fel-Pro High Temperature Alloy Material

The proprietary high temperature alloy material in Fel-Pro’s HTA gaskets retain their sealing performance up to 1600°F providing:

• Excellent torque retention.
• Superior performance over typical stainless-steel material that may crack or otherwise experience a loss of sealing contact stress at extreme high temperatures.

High Temperature Alloy Embossed Bead Recovery Test

Embossed sealing beads act as a spring to maintain sealing contact stress under most operating conditions. At extreme high temperatures, Fel-Pro’s embossed sealing beads maintain their integrity to effectively seal the joint as compared to typical stainless steel sealing beads that can soften, which results in gasket leakage.

Fel-Pro High Temperature Coating (HTC)

A key component of Fel-Pro HTA gaskets is a proprietary High Temperature Coating (HTC) that:

• Proprietary coating provides micro-sealing to accommodate surface imperfections.
• Reduces friction to prevent galling/scuffing of sealing surface.

Fel-Pro’s HTC has superior performance as compared to moly-coated and uncoated steel gaskets.

Applications

Fel-Pro’s proprietary HTA gaskets with HTC are available for certain turbo and exhaust manifold applications. Engineered with the right technology to handle the hotter temperatures associated with higher output engines, you can install Fel-Pro HTA gaskets with confidence.
