• The high density Die-Formed Ring in the upper and lower part will prevent the low density graphite from crack and
crushing by rotary and reciprocating.

• It guarantees better sealing effects if you use ALS970, ALS910C and ALS900G depending on the use purpose as end ring.

• There are three types of Packing Ring as below.

ALS 300

This is the bonnet exclusive gasket compressed and molded by inserting the heat-resistant alloy sheet into upper
and lower part after winding the graphite tape for over 99.8% high purity.
The graphite's self-lubrication capability and low coefficient of friction allow to use in a wide range without giving
damage on the reciprocating and rotary shaft.

ALS 355

Since the Die-Formed Ring was produced at a certain angle it can get outstanding sealing effect thanks to the low
tightening torgue load when assembling and coupling by gland.

ALS 357

Graphite tape is the packing compressed with the molding designed at different angles.
