K03 is a three piece single acting sealing set which consists of one reinforced cotton fabric backup ring , one elastomeric nitrile rubber middle ring , and one thermoplastic header ring.

PRODUCT ADVANTAGES
• Functions even with poor surfaces
• Easy installation
• Adjustable seal housing height due to the reason of being used in open grooves.

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.

Groove Base ØD ≤1.6 μm ≤6.3 μm
Groove Flanks B ≤3.2 μm ≤16 μm
Note: It is recommended to have 50% to 90% of the working surface material contact area value
 

INSTALLATION
Suitable for open piston housing. When strongly squeezed , the flexibility of the sealing set may be substantially reduced. This could cause by 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 with reinforced cotton fabric with FKM and special mixture of PTFE backup ring. Additional middle rings can be used depending on the application.
