Description

Pneumatic seal PSP 30×22×3,2 PU is a piston seal for pneumatic cylinders. It is made of grey polyurethane (PU), material code B0 (Artic Seals – Italy). Technical data: Outer diameter (D): 30 mm (1.18") Inner diameter (d₁): 22 mm (0.87") Height (h): 3,2 mm (0.13") Material: PU (B0 – polyether-based polyurethane, light grey) Hardness: 90 ShA Working pressure: up to 20 bar (in pneumatics) Speed: up to 1 m/s Manufacturer codes: Gapi code: 2EPSP151 Artic Seals code: PSP 0300 0220 032 B0 Manufacturer: Artic Seals (IT)

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).
