KASTAS PISTON SEALS K15
| K15 is a two piece double acting sealing set which consists of a special designed polyurethane seal ring and an o-ring as energizing element. |
| PRODUCT ADVANTAGES | |
| ● | High static and dynamic sealing effect |
| ● | Low axial housing heights |
| ● | Simple groove design, one-piece piston possible |
| ● | High abrasion resistance |
| APPLICATION |
| Light to medium duty industrial machinery, injection moulding machines, cranes and loading platforms. |

| Note: It is recommended to have 50% to 90% of the working surface material contact area value . |
| Easily assembled on one-piece piston. It is very important that the assembly tools must be of soft material and have no sharp edges.Before installation the sealing element must be oiled with system oil. |
| NOTES |
| cylinders, one guide ring in short stroke and under low radial loads.It is recommended to use with two piston guide rings in long stroke The permissible sealing gap values of K15 piston seal is given in the below table. |
