Maintain the structural pressure of your printing press with the Heidelberg O-Seal Ring (28 x 3 mm). This precision-molded component is essential for preventing leaks in pneumatic circuits, ink fountain systems, and hydraulic cylinders. Its specific dimensions and material composition are optimized for the demanding environment of an offset printing floor.
Technical Specifications:
-
Dimensions: 28 mm (Inside Diameter) x 3 mm (Cross Section/Thickness)
-
Material: NBR (Nitrile Butadiene Rubber) – high resistance to oils, hydraulic fluids, and compression set.
-
Hardness: Typically 70-80 Shore A (Industrial Standard for high-pressure seals).
-
Temperature Range: Effective from -30°C to +100°C.
-
Application: Static and dynamic sealing in pneumatic manifolds and cylinder end-caps.
Compatibility: This O-ring is a versatile sealing solution used extensively across the Heidelberg product line:
-
Speedmaster: SM 52, SM 74, SM 102, CD 102.
-
XL Series: XL 75, XL 105, XL 106.
-
Sub-assemblies: Common in ink fountain cylinders, wash-up devices, and pneumatic control blocks.
Performance Benefits:
-
Chemical Resistance: Formulated to resist swelling when in contact with common pressroom chemicals, solvents, and lubricants.
-
Leak Prevention: Precision sizing ensures a perfect fit, preventing air pressure drops that can lead to sheet-feeding errors.
-
Cost-Effective Maintenance: A small but vital component that prevents expensive damage to larger mechanical assemblies.
