Gasco Inc. is a trusted metal-jacketed gaskets manufacturer that has been offering quality gaskets that are used in sealing high-performance applications in the extreme industry. These gaskets are designed to be used under high pressure, in high temperatures, and under extreme chemical conditions, which makes them suitable in pipelines, heat exchangers, refineries, and petrochemical plants. They are very well built and do not leak; hence, they last a long time and need little maintenance. We are also the providers of Graphoil Ring Gaskets, which exhibit very high levels of chemical resistance and elasticity and thus can be used in specialised sealing jobs in high-pressure systems.
They come in different sizes, materials, and pressure ratings, and they are sold via a reliable B2B industry channel that ensures a steady level of quality, delivery time, and international standards. Products are evaluated on the level of strict quality and offer durability, the ability to be dimensionally accurate, and high sealing efficiency. The metal-jacketed gaskets and Graphoil ring gaskets are designed with high performance and reliability to provide industries with an efficient and long-lasting solution to safe operation without leaks in hard-to-contain industrial conditions.Metal Jacketed Gaskets

Metal Jacketed Gaskets
Type of Sub-products

Ring Type Joint (rtj) Gaskets Ring Type Joint (rtj) Gaskets
Ring Type Joint (RTJ) Gaskets are metallic precision gaskets designed for high-pressure and high-temperature flange sealing applications. Manufactured from premium alloys, RTJ gaskets provide superior mechanical strength, excellent chemical resistance, and reliable sealing performance. They are widely used in the oil, gas, petrochemical, and power industries for critical pipeline and pressure vessel connections.

Solid Metal Gaskets Solid Metal Gaskets
Solid Metal Gaskets are precision-engineered sealing components made from high-quality metals, offering excellent strength, corrosion resistance, and the ability to withstand high pressure and temperature. They provide reliable leak-proof performance in demanding industrial applications such as oil and gas, chemical processing, and power plants, ensuring long-term durability and safety in flange connections.
Frequently Asked Questions
What are Metal Jacketed Gaskets and why are they used?
Metal Jacketed Gaskets are classified as semi metallic gaskets used with a soft filler material, such as graphite or PTFE, and then surrounded by a metal jacket. This special construction is a mixture of the flexibility of the filler with the strength of metal, which gives them compatibility with high pressure and high temperature sealing. They are efficient installations to prevent leaks in sensitive industrial works where soft gaskets would not work.
What applications are Metal Jacketed Gaskets most suitable for?
Metal Jacketed Gaskets are very applicable in cases of heat exchangers, pressure vessel, gas pipe lines, and in chemical processing factories. They can perform in extreme conditions hence can be relied upon in petrochemical, oil and gas and power generation industries. Such gaskets are favored particularly where sealing faces demand additional strength and durability, or when flanges are thin.
How do Metal Jacketed Gaskets compare to other gasket types?
Metal jacketed gaskets are extremely temperature and pressure resistant compared to soft or traditional gaskets; that is why they are preferred in more important applications. In contrast to pure metal gaskets, they are still adaptable because of the easy soft filler, which causes a tighter seal on irregularities in the flange surfaces. At this amount of strength and flexibility, they can be used in industries that deal with performance and critical operations.
