Conafi General Purpose Gasket Sheet is an economical grade of compressed non-asbestos fibre (CNAF) gasket material designed for maximum versatility. It is produced from a combination of mineral and aramid fibres that are bound together with an NBR rubber binder. This construction allows Conafi to offer good strength and toughness while still remaining flexible and easy to handle.

Conafi is widely used in industry and, thanks to its versatility and all-round performance capabilities, is also well suited to a number of automotive, marine and domestic applications. These include gaskets for pumps, tanks, flanges and many other applications where various oils, chemicals, gas, salts, alkalis or water needs to be sealed. It’s usually used for medium pressure applications (up to abut 6MPa) and in applications where continuous temperatures fall between -30°C and +220°C.

Conafi has been widely tested and recognised by a number of international organisations including Germanischer Lloyd, DVGW, KTW and INIG.

Applications for Conafi Gaskets.

  • Water pipes and flanges.
  • Sealing gas or chemical lines.
  • Sealing strips for elevated temperature applications.
  • Automotive gaskets.
  • Sealing oils and petroleum.

FAQ's for Conafi Gasket Sheet.

Can I cut this gasket sheet myself?

You can. It’s definitely a little tougher to get through than cork or rubber (due to its highly compressed construction and the presence of the aramid fibres) but you can get through it with a box cutter (Stanley knife). There’s also dedicated gasket cutters that will get through it nicely.

Cutting your own gaskets from Conafi General Purpose Gasket Sheet can be made a little easier but ensuring you have a really sharp knife at the ready, being prepared to make multiple shallow cuts through the material and wetting the blade, with water, from time to time. We don’t really suggest scissors for anything over about 1.5mm thick as these can be a little hard on the wrist muscles.

How often do I have to replace gaskets made from this material?

This is a hard one to answer as it will vary depending on the exact operating conditions (fluid being sealed, temperature and pressure being the big 3 factors). Generally, once the gasket is properly installed and the flange is assembled you can expect years and years of performance.

If the flange is taken apart (especially after the gasket has been in full blown service for quite a while) you may then need to replace it as recovery will be compromised which means that it will not compress as much as previous and a good seal may be hard to achieve.

Do I need to use any gasket goo with this material?

No. Generally speaking Conafi is designed to work by itself. In some situations, they can help (like when you need to make sure the gasket won’t stick to the flanges even after years of service or when sealing at lower bolt loads) but they’re not required for most applications for Conafi.

Does this material contain any asbestos?

Definitely not. We are very careful to ensure that all of our materials are 100% asbestos free. Conafi is no exception.
