product details

 PDR type is a dust seal for cylinder piston rod.

  Application scope:

    Working pressure: ≤ 1.6Mpa
    Operating temperature: – 30C ~ + 80C °
    Reciprocating speed: ≤ 1m / S

  Media:

    compressed air

  Installation:

   Such seals shall have axial clearance and integral piston can be used. In order to avoid damage to the sealing lip, measures should be taken to avoid sharp edges during installation

  Material Science:

    High performance NBR with shore hardness of 75 degrees

  Ordering example:

  PDR-20 or PDR-20 28 5.5/7.5

Material Temp. Range (°C) Property
Low Temp. Hight Temp.
NBR -40 100 Good resistance to alcohol, amines, petroleum oils,and gasoline over a wide range of temperatures.
Also good resistance to caustic salts. Poor in strong oxidizing agents, chlorinated hydrocarbons, ketones,and esters.
FKM -25 250 Excellent chemical resistance but ester and ketone.
The cost is high. Good resistance to most oil and solvents
PU -40 100 Extremely good tensile strength, abrasive resistance,tear strength, and extrusion strength but poor resistant to polar solvents, chlorinated hydrocarbons,aromatics, brake fluids, acids, and alkalis.
