The braided gasket - also known as braided gasket, braided packing ring, braided cord, packing cord, water pump gasket, valve gasket, etc. - is an indispensable seal for dynamic applications such as pumps, valves and other rotating equipment in industrial process plants.
The braided gasket is designed to seal between the shaft or spindle and the fixed pump housing or stuffing box to prevent leakage of liquids and gases.
Main types of braided gaskets
There are several types of braided gaskets, each with their unique properties, applications, advantages and disadvantages. Here are some of the most common:
Braided gasket with graphite yarn
These gaskets are known for their high temperature and pressure resistance. They are ideal for use in extreme environments where other gasket types may fail.
Braided gasket with PTFE yarn
PTFE, or polytetrafluoroethylene, is a material known for its chemical resistance. These gaskets are ideal for use in chemical processes where they can withstand aggressive media.
Braided gasket with aramid fibers
Aramid is a strong and durable material that is ideal for use in high-pressure applications. These gaskets are known for their durability and long service life.
Braided gaskets are used here
Braided gaskets are used in a wide range of industries and applications. Here are some of the most common:
Energy & utilities
In power plants, heating plants and other energy production and distribution facilities, braided gaskets are used to seal pipes and hatches (static application), valves and pumps (dynamic application) and other systems with liquids and gases under high pressure and temperature.
Braided gaskets, especially the PTFE type, are safe to use in food production as they are resistant to bacteria and other microorganisms.
Due to their chemical resistance, braided gaskets are often used in chemical processing plants where they can withstand aggressive media.
Know the benefits and limitations of braided gaskets
Braided gaskets are a common seal type in many applications in industrial process plants, cargo pumps and transportation augers. It is important to understand the different types, their applications, as well as their benefits and limitations.
braided gaskets - benefits
- Temperature and pressure resistance
Braided gaskets can withstand extreme temperatures and pressures, making them ideal for use in demanding industrial environments.
- Chemical resistance
Many types of braided gaskets are resistant to a wide range of chemicals, making them ideal for use in chemical processes.
Braided gaskets are known for their durability and long lifespan, which can reduce maintenance costs and downtime in many industrial processes.
braided gaskets - limitations
Braided gaskets require professional installation to ensure they function properly. This can increase the overall cost.
Some types of braided gaskets, especially those made from specialized materials like PTFE or graphite, can be more expensive than simpler gasket types.
- Not suitable for all applications
Although braided gaskets are very versatile, they are not suitable for all applications. For example, they are not always the best choice in highly corrosive environments or where there is significant abrasive wear (material degradation particles).

Braided gasket with aramid - LATTYflon 4788
Braided gasket (shaft seal) made from 100 percent aramid fibers. Each yarn is impregnated with PTFE using a unique "Filcoat" process. Then further impregnated with a mixture of PTFE and food-grade quality lubricant.
Very high mechanical performance. PH values for media: 2 to 13. Working temperature: -220 to 300 °C.
Mixed yarn braided packing - LATTYflon 4757
A very strong multi-yarn gasket (shaft seal). The corners are made of 100 percent aramid yarn impregnated with PTFE. The lubricated friction surfaces are made of 100 percent graphitized PTFE yarn. The entire seal is further impregnated with a mixture of PTFE and a lubricant.
Combining the benefits of graphite, PTFE and aramid, this gasket achieves high mechanical abrasion resistance.
PH values for media: 2 to 14. Working temperature: -220 to 300 °C.
Vegetable yarn braided gasket - LATTYflon 1779
A plant-based packing cord (shaft seal) made from high-quality ramie yarn (Boehmeria nivea) with anti-rot treatment.
Impregnated with a mixture of PTFE and lubricant during the braiding process.
PH values for media: 4 to 11. Working temperature: -40 to 120 °C.
Flexible braided gaskets - LubSeal
The LubSeal series from Nordic Seal is a flexible gasket (shaft seal) with an elastomer core and an outer sheath of braided fibers.
- A reservoir inside the hollow core allows a lubricant to be added to the seals.
- Pre-shrunk, cut and ready to install.
- Properties that extend the life of the sealing solution.
choose between EPDM / NBR / Silicone, each in 5 different hardnesses (Shore A).
choose between 3 different fiber materials: Aramid / Polyamide / PTFE.
choose between graphite, PTFE or none (dry).
With the options of cores, fiber materials and lubrication, it's possible to configure a unique, customized sealing solution.
The flexible, braided gasket is supplied as pre-formed rings. Different sealing profiles are also possible.
