Y/W/O type seal ring
Introduction:
The Y/W/O type seal ring is a special high performance product.
The rubber seal ring is made up of the high quality rubber or the high quality rubber combined with fabric, which conforms to the <The petrol base oil type pipeline and the rubber seal material for connection> HG/T3093, GB/T 10708, ASTM D412 and ASTM D2240 standard.
The main advantage of the seal ring is high elastic, aging resistant and good stability. It is adapt for the petrol mechanic industry, which shares a high cost performance compared to the other same type imported seal ring.
● Reasonable structure, best size to match, easy to assemble and remove
● Seal temperature range: —40℃～+150℃
● Static and dynamic seal both available
● Small dynamic friction force
● High mechanic strength
● High stability, not easy to swell in the petrol medium
● High corrosion resistant, not easy to age, long working age
● High activity, adaptation
● Compensate a big seal and angle tolerance
● Simple structure, easy to use and maintain
● Good wear resistance
● Good physical mechanical performance, high cost performance
Parameter:
● Hardness: 60±5,,70±5,80±5,88±5
● Tensile strength: ≥15MPa
● Tensile elongation rate: ≥250%:～≥100
● Compress to permanent deformation: B type, 100℃×22h,≤20%
● Hot air aging: 100℃×70h, hardness 0～+10; the strength change rate≤15%, the change rate of elongation rate≤25%
● 1# standard oil resistant: 100℃×70h, change of hardness-3～+8, change of volume -10～+5
● 3# standard oil resistant: 100℃×70h, change of hardness-14～0, change of volume 0～+16
● Low temperature brittleness: -18℃；-40℃；-60℃
● Compressing stress loosen, Ⅱtype sample, standard room temperature×7d, ≤15%
● Compressing stress loosen, Ⅱtype sample, standard room temperature×90d, ≤22%
● Effects of oil resistant, leaking preventing, waterproof, decreasing vibration and noise, seal and damping.
