Low-emission packing plays a crucial role in modern industrial sealing, providing reliable performance in demanding applications such as valves, pumps, compressors, and agitators. Engineered to minimize fugitive emissions, it ensures compliance with stringent environmental and safety regulations while maintaining system efficiency.

Our packing is manufactured using premium-grade materials, including:

PTFE – delivering exceptional chemical resistance and low friction.

Expanded graphite fibers (with over 98% carbon content) – offering superior thermal stability, oxidation resistance, and sealing capability.

Inconel wire reinforcement – enhancing mechanical strength, pressure resistance, and durability in high-temperature, high-pressure environments.

This unique combination of materials, along with optimized density and surface texture, ensures:

Very low friction coefficients, reducing wear on valve stems and pump shafts.

Minimal leakage rates, even under severe thermal cycling, corrosive media, and elevated pressures.

Extended service life, lowering maintenance frequency and total operating costs.

To guarantee safety, performance, and regulatory compliance, our low-emission packing is tested and certified to internationally recognized standards, including:

API 622 – performance qualification for fugitive emissions in valve stem packing.

ISO 15848-1 – measurement and qualification of fugitive emissions for industrial valves.

TA Luft (Germany) – compliance with stringent environmental emission control requirements.

These certifications demonstrate the quality, reliability, and effectiveness of our packing in reducing emissions and supporting sustainable operations. It is ideally suited for use in industries such as petrochemical, power generation, chemical processing, pharmaceuticals, and refineries, where safety, environmental protection, and operational integrity are paramount. https://www.valvegasketboltnuts.com/packing.html

Low Emission Packing Manufacturer China | Topper

China Low Emission Packing Manufacturer Provides Valve Packing Made from Graphite, PTFE, Reinforced by Inconel/SS, Achieving Good Sealing of Valves.

Gaskets play a vital role as sealing elements in a wide range of equipment, including pumps, pipe valves, pressure vessels, reaction tower kettles, and other process systems. They are strategically positioned between two flanges to provide a reliable seal, effectively preventing fluid or gas leakage at the joint and ensuring the safe, stable, and efficient operation of the system.

At TOPPER, we specialize in producing high-quality gaskets tailored to meet the demands of diverse industries and applications. Our gasket portfolio is broadly divided into two categories: metal gaskets and insulating gaskets.

Metal Gaskets:
These include spiral wound gaskets and metal ring gaskets, both known for their ability to perform under high pressure, high temperature, and corrosive conditions. Spiral wound gaskets combine metal and soft filler materials to deliver excellent resilience and sealing integrity, making them widely used in the petroleum, petrochemical, and food processing industries. Metal ring gaskets, often manufactured to API standards, are particularly suitable for high-pressure pipeline connections and are widely adopted in the oil and gas sector.

Insulating Gaskets:
This category includes graphite gaskets and PTFE gaskets, which are valued for their superior chemical resistance and ability to handle a wide range of media. Graphite gaskets offer excellent thermal stability and are ideal for applications involving extreme temperatures and aggressive chemicals, while PTFE gaskets provide outstanding resistance to corrosive fluids and low-friction properties, making them suitable for industries such as chemical processing, pharmaceuticals, and food production.

In addition, flange isolation kits are offered as part of our gasket solutions. These kits are specifically engineered for use in cathodic protection systems within pipelines, effectively preventing galvanic corrosion by electrically isolating different sections of piping systems. They are widely utilized in oil, gas, water, and chemical pipelines, where long-term protection against corrosion is essential.

By combining advanced materials, precision manufacturing, and strict quality standards, TOPPER ensures that every gasket and isolation kit delivers dependable sealing performance, extended service life, and maximum safety for critical industrial operations. https://www.valvegasketboltnuts.com/gasket.html
