Mr. Gasket Catalog
Restore. Restyle. Relive. PRODUCT CATALOG THE MR. GASKET STORY Back in 1964, Joe Hrudka was a drag racer in Northern Ohio who was looking to solve a problem that parts manufacturers had not addressed. Using his own 1957 Chevy drag race car as a test vehicle, he created a line of engine gaskets and fasteners proven to seal and withstand extreme temperatures, pressures and stresses created by high performance engines. This product line that was developed by a drag racer would evolve into a brand of legendary proportions over the next 50 years. Mr. Gasket started with Joe’s ‘57 Chevy and has continued to advance and expand with application coverage and even more new products for muscle cars. Head gaskets, exhaust gaskets and oil pan gaskets were just the beginning. The Mr. Gasket brand develops and distributes a variety of performance parts for your vehicle including: carburetor and fuel accessories, chrome-plated accessories, cooling system accessories, engine components, fuel additives, shifter accessories, specialty tools, suspension and driveline components. Located in Cleveland, Ohio, the Mr. Gasket team continues to design, develop, manufacture and distribute products that bring back the luster and performance that everyone remembers to a variety of auto projects. It may have started with a Chevrolet, but when you are ready to Restore, Restyle and Rebuild your car, Mr. Gasket is who you can trust to have the parts and advice you need to complete your project.

Exhaust/Emissions Systems Overview Emissions Testing
Exhaust/Emissions Systems Overview Below is an overview of this system's operation Emissions Testing Many states require emissions tests on vehicles. This means that you drive to a facility where the test people take a sample of your emissions and run it through some analysis. The results are printed,and you pass or fail depending on the percentage of toxic emissions that turn up in your car's sample. The only way to "study" or prepare for this test is to take good care of your car, including its emission system. If you use preventative maintenance, and keep your car tuned properly, you will pass. If you tamper with your emissions system, you will not pass. You can have your car checked independently before your emissions test if you want to resolve problems before going to the emissions test station. One other good thing to do is to save your printouts from the test from year to year. If you compare them, you will be able to monitor your car (if its score is getting worse) and catch any problems before the emissions people catch you. The Emission Control System The purpose of the emission control system is just that; it controls the emissions and exhaust from your vehicle. The idea is to turn the harmful gases your car manufactures into harmless ones that don't ruin the environment, or us. Some of the problem gases are: • hydrocarbons (unburned) • carbon monoxide • carbon dioxide • nitrogen oxides • sulfur dioxide • phosphorus • lead and other metals To help control these substances, we (along with federal regulations) have made changes in our gasoline to eliminate them.

Exhaust Muffler Design Principles
3.0 Exhaust Muffler Design Principles 3.1 Basic Concepts Internal combustion engines are typically equipped with an exhaust muffler to suppress the acoustic pulse generated by the combustion process. A high intensity pressure wave generated by combustion in the engine cylinder propagates along the exhaust pipe and radiates from the exhaust pipe termination. The pulse repeats at the firing frequency of the engine which is defined by f=(engine rpm x number of cylinders)/120 for a four stroke engine. The frequency content of exhaust noise is dominated by a pulse at the firing frequency, but it also has a broadband component to its spectrum which extends to higher frequencies. Measurements of the exhaust pipe pressure pulse on a Continental O- 200 engine [4] show that the majority of the pulse energy lies in the frequency range of 0- 600 Hz. Exhaust mufflers are designed to reduce sound levels at these frequencies. In general, sound waves propagating along a pipe can be attenuated using either a dissipative or a reactive muffler. A dissipative muffler uses sound absorbing material to take energy out of the acoustic motion in the wave, as it propagates through the muffler. Reactive silencers, which are commonly used in automotive applications, reflect the sound waves back towards the source and prevent sound from being transmitted along the pipe. Reactive silencer design is based either on the principle of a Helmholtz resonator or an expansion chamber, and requires the use of acoustic transmission line theory. In a Helmholtz resonator design a cavity is attached to the exhaust pipe.

Gruvlok Gasket-Styles
TECHNICAL DATA SHEETS TECHNICAL DATA SHEETS GRUVLOK GASKET-STYLES Gruvlok offers a variety of pressure responsive gasket styles. Each serves a specific function while utilizing the same basic sealing concept. Proper installation of the gasket compresses the inclined gasket lips on the pipe O.D., forming a leak tight seal. This sealing action is reinforced when the gasket is encompassed and compressed by the coupling housings. The application of internal line pressure energizes the elastometric gasket and further enhances the gasket sealing action. “C” STYLE The “C” Style cross section configuration is the most widely used ® gasket. It is the gasket style provided ROUGHNECK as standard in many Gruvlok Couplings This “C” style gasket is (Fig. 7000, 7001, 7003, 7004HPR, 7307, similar in appearance 7400 and 7401). Grade “E” and “T” are standard grades while other grades and design to the are available for special applications.

This includes: SUVs Trucks Vans Cars What Does a Head Gasket Do? As part of your vehicle’s internal combustion engine, both oil and coolant play an integral role in the functioning of your automobile, and it is vital that these both be kept separate from each other. The head gasket acts as a seal, and it is situated between the engine block and the cylinder head. It is important that the oil and coolant remain in their own channels and that they don’t leak into the combustion chamber, out of the engine altogether, or into each other’s chambers. Your engine’s head gasket is continually subject to contrasting temperatures and conditions. It is exposed to the heat that is produced in the combustion chamber, and it is subject to the cold that is produced by the components that are designed to keep your vehicle cool. It is shaped like a panel with one circle for every cylinder that the engine houses. This environment of extremes can sometimes cause your head gasket to warp, and if left untended, this can cause your head gasket to blow. What Are Some Ways to Tell That My Head Gasket Has Blown? It is crucial that you be able to recognize the signs and symptoms that you’re dealing with a blown head gasket.
