Introduction to Gasket

Gasket is a seal that fills the space between 2 or more in-contact surfaces to prevent leaks and spills from or into the surfaces while being compressed.

Gasket can be classified in many ways: by material, function, sector/industry. It is important to choose the right Gasket for your application to avoid safety or equipment risk. To know more about gasket, read our blog: “Types of Gaskets” here.

Introduction to Task-Line®

Task-Line^® is a unique PTFE gasket with SS304 insert. Virgin PTFE is molded around and through SS304 perforated metal insert before goes through oven sintering. It is blowout-proof, creep-resistant and tightly seated (no bolt-retorquing). The metal filler enhances its hardness, compressive strength and dimensional stability, making Task-Line^® is safer and more durable than the normal gasket.

In addition, Task-Line utilizes PTFE, one of the high-performance materials in the industry. PTFE protects flange joints from almost all aggressive chemical, providing maximum protection for your workers and equipment. Moreover, PTFE is non-stick, non-wettable, and thermal-resistant.

Task-Line^® is manufactured in the U.S. and is designed to comply with a proprietary and FDA approval process. Every Task-line® gasket has undergone 15,000-volt spark test to ensure that they are pinholes free!

Summary of Task-Line®

Task-Line^® is a PTFE gasket with a revolutionary design that resulted in various benefits such as:

1. Durability

The SS304 insert provides a higher pressure rating that prevents tear when under pressure.

2. Reusability

Task-Line^® gaskets are leak-free and bubble tight and can be used over and over without sacrificing sealing ability. Furthermore, its high durability also supports its reusability.

3. Chemical Resistant

Task-Line^® gasket is chemically resistant to all acids, all chlorides, sulphates, bleach solutions, solvents, phenols, caustics and peroxides.

4. Prevent Bolt Retorquing

The metal insert prevents radial flow of the gasket, makes it difficult for bolt retorquing to occur, hence maintaining a tight seal even through repeated temperature cycles. Moreover, the strength of the metal insert also provides a critical blowout-proof protection.

5. Creep or Cold Flow Resistance

PTFE Encapsulated metal insert restricts the PTFE from cold flow/creep while under load. Giving itself a longer lifespan.

6. Wide Temperature Range

Task-line® gaskets are stable enough for cryogenic use up to 400^oF/204^oC.

7. Self-aligning and Self-Seating

Task-Line^® offers quick and simple installation because it can self-align and seat easily to any flange in almost any condition.

8. Non-Stick

Due to PTFE’s non-stick property, Task-Line^® gasket can be released from flanges easily during disassembly without scraping.

Why Should We Use Task-Line®?

Wah Joo Seng’s Task-Line^® is made to overcome many challenges that other gaskets face. See how it outperforms other gaskets that you might know.

Virgin PTFE Gasket vs Task-Line®

Virgin PTFE makes a wonderful gasket; but it lacks hardness, creep-resistance and pressure rating due to the lack of metal insert. Task-Line^® Gasket offers all the benefits of blowout-proof protection, creep resistance and prevent bolt retorquing by including SS304 perforated metal insert.

Spiral Wound Gasket vs Task-Line®

Task-Line^® gasket has better durability and reusability than spiral wound/stripwound gasket. This makes Task-Line^® more economical since Spiral Wound gasket is only applicable for one-time usage.

Sheet Gasket vs Task-Line®

Like virgin Ptfe Gasket, sheet gasket lacks metal insert hence it is more susceptible to blowout, bolt retorquing and cold flow/creep. However, they are still recommended for mild or low-pressure application.

Viton Gasket vs Task-Line®

Task-Line^® has a better versatility as it can cope with more chemicals than Viton gasket. However, PTFE and Viton are used for different application, it is recommended to check our chemical resistance chart here prior to using the gaskets.

Rubber/Plastic Gasket vs Task-Line®

Rubber/Plastic is only applicable for mild application due to its low chemical resistance. Task-Line^®, however, is far more superior than rubber/plastic gasket as it can handle aggressive chemicals such as chloride and sulphate acid.

Final Words
