K01

K01 is a seven piece single acting sealing set which consists of one reinforced cotton fabric backup ring , one thermoplastic header ring , three reinforced cotton fabric middle rings , and two elastomeric nitrile rubber middle rings.

PRODUCT ADVANTAGES
• Adjustable seal housing height due to the reason of being usedin open grooves.
• Functions even with poor surfaces
• Robust seal
• Easy installation and removal
• Long service life
• Able to work until the maintenance of continuity systemsbecause of the adjustable housing
• Very good sealing performance both in high and low pressures

APPLICATION
Used especially in hard working conditions such as iron and steel industry , mining equipment , marine hydraulics , scrap cutters and special cylinders where the actual conditions are difficult to predict.

INSTALLATION
Being assembled in adjustable housing , the groove housing should have an adjustability of 7.5% of the seal height. If there is a requirement of being used in closed housings , individual parts should be cut with 45° angle and staggered by 75° angle at installation. When strongly squeezed , the flexibility of the sealing set may be substantially reduced. This could cause excessive friction force , high wear and vibrated operating under low pressures. It is very important that the assembly tools must be of soft material and have no sharp edges. Before installation all individual parts of the seal must be oiled with system oil.

NOTES
For special applications that require high temperatures , our seal set is being manufactured in the following configuration , reinforced cotton fabric with FKM for header and middle rings and special mixture of PTFE backup ring. Permissible sealing gap S value should not be above 0.15 mm. For inner diameters above 200 mm , all the middle rings are being produced from reinforced cotton fabric with NBR material. Additional middle rings can be used depending on the application.
