| Note: It is recommended to have 50% to 90% of the working surface material contact area value |
| INSTALLATION |
| open grooves taking the indicated catalogue information into K16 profile has been designed to be installed in a closed or consideration. We recommend having open groove design for dimensions that are smaller than Ø 50 mm. 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 |
| For special applications that require high temperatures, our seal set is being manufactured with reinforced cotton fabric with FKM and special mixture of PTFE guide back-up rings. |
