Primary packing solid and hollow plug

Primary packing solid and hollow plug – This is the main seal in the Access Fitting Assembly. It is primarily made of glass filledTeflon® which provides an excellent seal against most fluid types. Teflon is not resilient like elastomers and willcold flow under pressure.

This means when the packing is compressed in its seat, it will flow into all gaps, creating an excellent seal. However, the packing will not return to shape when removed and therefore it should be
replaced whenever the plug is removed from the fitting.
