AF Oil is a compressed non-asbestos jointing-sheet material produced from Aramid fibres, bonded with Nitrile Rubber (NBR). It is being manufactured by means of a hot calender process under rigorous quality control standards which are registered under ISO 9001 certification.

What is non-asbestos gasket?

Non-asbestos gasket sheets are made using organic fibers, aramid fibers, NBR and mineral fibers. These can be used for application where water or oil resistance is required. Generally, non-asbestos gasket sheets are used in low-pressure apparatus, transformers, and compressors.

What will replace asbestos gaskets?

Manufacturers found that other compressed, resilient fibers such as Kevlar and graphite were a safe and effective replacement to asbestos gaskets. Two of the most common brands for non-asbestos gaskets, ones you’ll often see on the shop floor of Breiner Non-Metallics, are Thermoseal (Klinger) and Garlock.

What is the difference between asbestos and non-asbestos?

Non-Asbestos Fibre materials are so-called because they fill the gap in the range of gasket materials previously occupied by asbestos. Asbestos, although considered to be a dangerous material, had excellent heat resistance properties, which is why it was utilised so widely in high temperature applications.

When would you use an asbestos gasket?

How Were Asbestos Gaskets Used? Asbestos-based gaskets were used to create a tight seal between pipes or pieces of machinery in engines and heavy industry.

What is the best head gasket material?

Carbon gaskets offer superior sealing even on the worst flange surfaces. They can withstand long-term exposure to high temperatures, so they’re perfect for your nitrous, turbo, or blower application. Composite gaskets resist coolant, gasoline, alcohol, and oil, and can be easily trimmed for exact fit on modified parts.

When did asbestos gaskets stop?

In July 1989, the U.S. Environmental Protection Agency (EPA) prohibited the manufacture, importation, processing, and distribution in commerce of most asbestos gaskets by 1994. EPA’s decision to ban asbestos gaskets was based solely on exposure data obtained from the gasket manufacturers.

Was asbestos used in gaskets?

Where do you find this? Asbestos rope seals and gaskets can be found in gas or electric heating appliances.

How much asbestos is in a gasket?

Sheet gasket material commonly contained up to 70% to 80% chrysotile asbestos. Gaskets designed for acidic environments often contained a more dangerous form of asbestos called crocidolite, which is also known as blue asbestos. The fiber filler in spiral wound gaskets was often almost completely pure asbestos.
