Description

Rod seal RSD 120x128x11,5 PU is a product offered by the Italian manufacturer Artic Seals. This is a double-lip ring made of polyurethane C0, intended for use in hydraulic cylinders. Seal size: Inner diameter: 120 mm Outer diameter: 128 mm Ring height: 11,5 mm Manufacturer code: 2ERSD725 Material: Polyurethane (PU) Technical data: Working pressure: up to 400 bar Linear speed: up to 0,5 m/s Hardness: 93 Shore A ±2 Material: polyurethane C0 with high abrasion resistance and low compression set Rod seal RSD 120x128x11,5 PU is a gland seal whose design prevents the stick-slip effect and supports sealing performance at low temperatures. The additional lip stabilises the seal and protects it against external contamination.

Material

PU / TPU / H-PU (polyurethane)

  • Standard PU / TPU-30 °C to +80 °C

Best for high pressure and abrasion, in mineral hydraulic oil. Standard PU must never meet hot water, steam or brake fluid, or run hotter than +90 °C.

Chemical resistance
Can be usedDo not use
Extreme pressure and pulsation (up to 40-50 MPa, very resistant to extrusion into the gap)Hot water and steam with standard PU: hydrolysis, it breaks down into powder
Abrasion, friction, cutting and tearing (4-5 times tougher than NBR)Glycol brake fluid (DOT 3, DOT 4, DOT 5.1): swells quickly
Mineral hydraulic oil (HL, HLP) and greaseHigh temperatures above +90 to +100 °C with standard TPU: it softens
Fuel oil, diesel and technical oils (aliphatic hydrocarbons)Strong (concentrated) acids and alkalis: sulfuric, nitric, caustic soda
Ozone, weather and sunlight (does not crack from weather)Acetone, MEK, toluene, benzene, dichloromethane (polar and aromatic solvents)
Water-based fire-resistant fluids HFA, HFB (only special H-PU)Synthetic ester oils and fire-resistant fluid HFD-R
Dry compressed air and technical gasesStrong alcohols (methanol, ethanol): swelling

Water and heat destroy standard PU: above +50 to +60 °C in water or damp oil it turns into a sticky paste or crumbles. If the system contains water or an emulsion, use only H-PU (hydrolysis-resistant).
