Sealpilot specializes in supplying a wide range of packings, materials and processes to meet all of our customers' sealing needs.
Packing, also known as sealing packing, is usually made of softer threads, usually with a square or rectangular and round strip filled in the sealing cavity with a cross-sectional area, so as to achieve sealing. Packing seals were first used to plug cotton and linen and other fibers in the leakage channel to prevent liquid leakage, and were mainly used as shaft seals for water lifting machinery. Due to the wide source of filler, easy processing, low price, reliable sealing, and simple operation, it has been used to this day. Today, packing is widely used in the shaft seals of centrifugal pumps, compressors, vacuum pumps, mixers and ship propellers, the reciprocating motion shaft seals of piston pumps, compressors and refrigerators, and the rotary seals of various valve stems.
Carbon fiber braided packing is a packing made of acrylic fiber pre-oxidation, and the surface is treated with PTFE emulsion and lubricant.

Aramid fiber woven packing is made of DuPont Kevlar fiber, impregnated with PTFE emulsion and other lubricants and then woven into a square cross-section. Because the strength and modulus of Kevlar fiber are the strength of steel wire, this packing can withstand higher medium pressure than other braided packing, and it can be installed separately from other types of half packings or as end rings, which can form packing groups with various characteristics.

PTFE braided packing is a braided packing made of PTFE thread, which is not impregnated with any PTFE emulsion and grease, and has the performance of sealing high-speed rotating shaft and additional high temperature resistant agent, which is recommended to be used in chemical, food, pharmaceutical and other operations that do not allow pollution, and can also be used for sealing all chemical media except soluble alkali metals.

Expanded graphite packing, also known as flexible graphite packing, is made of flexible graphite wire woven through the center. Expanded graphite packing has the advantages of good self-lubrication and thermal conductivity, small friction coefficient, strong versatility, good flexibility, high strength, and protection of shaft rods. According to different requirements, carbon fiber, copper wire, 304, 316L, incaustic nickel alloy wire and other materials can be used.

Aramid fiber packing is made by treating and weaving aramid fibers impregnated with lubricants such as PTFE emulsion and silicone oil. It has good chemical resistance, high resilience and low cold flow. It has excellent properties of high rotational speed and high modulus (known as artificial metal wire). Therefore, compared to other types of packing, it is resistant to granular crystallization media and can be used alone or in combination with other packings. It is a good asbestos substitute on the pump system.

End Rings: Braided high-purity filler made of expanded graphite Inconel wire wrapped yarn for high strength and extrusion resistance with excellent sealing. The filler is impregnated with a proprietary emulsion that is resistant to high temperatures to ensure extremely low friction.
Intermediate rings: Special molded rings for high-purity graphite foil with low friction and excellent heat transfer characteristics, as well as efficient sealing.
