CYLINDER HEAD AND MANIFOLD GASKETS

The basic materials used are divided into two types and the finished gaskets derived from these are sometimes coated or have silicon beading to assist sealing.

ADC

A laminate consisting of a steel perforated or tongued centre layer, with facings on the outside
- normally black or dark grey.

ADF

Consists of Steel/Jointing/Steel laminate which is the reverse of ADC and is used mainly on high temperature exhaust pipe and flange gaskets.

Specifications
The steel sheets are tongued so that the tines penetrate the jointing and the frequency of perforations are 4-5per cm.
Compressibility: 16% Recovery: 34% (min) Temperature Limit: 600C
