Low-emission packing plays a vital role in ensuring reliable sealing and environmental compliance across a wide range of industrial applications, including valves, pumps, and rotating equipment. Engineered to minimize fugitive emissions, our packing solutions are specifically designed for industries that demand high sealing integrity and adherence to strict regulatory standards.

Manufactured from premium-grade materials such as PTFE and expanded graphite fibers with a carbon content exceeding 98%, our low-emission packing offers outstanding thermal and chemical resistance. To further enhance strength and mechanical stability, the packing is reinforced with Inconel wire—providing exceptional performance under high-pressure and high-temperature conditions.

Thanks to its optimized density and finely engineered surface texture, our packing exhibits ultra-low friction and leakage rates, making it suitable for both dynamic and static sealing applications. This ensures long-lasting performance, reduced wear on valve stems and shafts, and decreased maintenance intervals—ultimately improving plant efficiency and reliability.

Our low-emission packing complies with major international standards, including TA Luft, API 622, and ISO 15848-1, confirming its superior sealing capability and environmental safety. These certifications serve as a testament to the product's quality, reliability, and effectiveness in reducing harmful emissions in even the most demanding operational environments.

Whether deployed in petrochemical plants, power stations, refineries, or chemical processing facilities, our low-emission packing delivers robust, long-term sealing solutions that support both performance and sustainability goals. https://www.valvegasketboltnuts.com/packing.html

Gaskets are vital sealing components used across a wide range of industrial equipment, including pumps, pipe valves, pressure tanks, reaction tower kettles, and many others. Installed between two flanges, gaskets provide a secure and reliable seal to prevent leakage at the joint, ensuring the safe and efficient operation of the system.

TOPPER specializes in offering two primary categories of gaskets: metal gaskets and insulating gaskets. The metal gasket range includes spiral wound gaskets and metal ring gaskets, both engineered for durability and excellent sealing performance. These metal gaskets are extensively used in demanding industries such as petroleum, petrochemical, and food processing, where safety, reliability, and compliance with strict industry standards are critical.

In addition, TOPPER provides insulating gaskets, including graphite and PTFE gaskets, designed to offer superior chemical resistance, thermal stability, and electrical insulation. These insulating gaskets are ideal for applications that require protection against corrosion or electrical isolation between flanged joints.

Moreover, TOPPER supplies flange isolation kits specifically developed for cathodic protection systems used in pipeline infrastructure. These kits prevent galvanic corrosion by electrically isolating flanged connections, thereby extending pipeline lifespan and ensuring long-term operational integrity.

Together, TOPPER’s comprehensive gasket solutions and flange isolation kits deliver robust sealing and protection tailored to meet the diverse needs of various industrial sectors.
