Description

The K22 20x32x6 ring is a single-acting rod seal used in industrial hydraulics. It has a classic U-cup design, providing effective sealing in hydraulic cylinders. It is made of NBR elastomer, which makes it suitable for many standard hydraulic systems. Technical parameters: Inner diameter (d): 20 mm Outer diameter (D): 32 mm Height (H): 6 mm Size in inches: d x D x H = 20x32x6 mm ≈ 0.79”x1.26”x0.24” Material: NBR Seal type: single-acting U-ring (U-cup) Application: sealing of hydraulic piston rods

Material

NBR (nitrile butadiene rubber)

  • Operating temperature-30 °C to +100 °C

Good with oils, fuels, water and compressed air. Not for brake fluid, solvents, strong acids or sunlight.

Chemical resistance
Can be usedDo not use
Mineral oil, grease and hydraulic oil (H, H-L, H-LP)Brake fluid (DOT 3, DOT 4, DOT 5.1): the ring swells quickly
Diesel, fuel oil, keroseneSunlight and open air (ozone): the rubber cracks
Petrol (gasoline), propane, butaneAcetone, MEK, ethyl acetate and similar solvents
Water and water-based liquids, up to +80 °CBenzene, toluene, trichloroethylene (aromatic and chlorinated solvents)
Compressed air, also with oil mistSynthetic ester oils and fire-resistant fluid HFD-R
Water-based fire-resistant hydraulic fluids (HFA, HFB, HFC)Strong (concentrated) acids, e.g. nitric and sulfuric, and strong oxidizers
Oil-and-water emulsionsSteam and hot water above +100 °C
Weak acids, alkalis and salt solutions, at room temperature
Use with cautionPetrol with a lot of bioethanol (E10, E85): better use FKM (Viton)

Shows low compression set within the recommended temperature range.
