Name:O Type sealing ring
Material:Nitrile butadiene rubber NBR(Black)
Temperature:-25℃ to 100℃
Shore Hardness: 70°
Wire Diameter CS :1mm/1.5mm/2mm/3mm, Outer diameter: 3mm to 50mm
Size:Our size is outer diameter(OD) * wire diameter(CS), inner  diameter(ID)= outer diameter - 2 x wire diameter
E.g:outer diameter 20*2mm, which means outer diameter is 20mm, wire diameter is 2mm, then inner diameter=20-2*2=16mm, and so on;

Product Feature:

Advantage:DurableNitrile butadiene rubberwith resistance to heat, oil, aging, abrasion, ozone, fuel and chemical;  Strong sealing and good airtightness

Feature:O-ring round in cross-section to provide a seal between cylindrical overlapping surfaces.  They are commonly seen in engines, flanges, valves, Automotive, mechanical seals, pumps, constant pressure valves, instrumentation and so on

Application:Nitrile butadiene rubberO-ring provides sealing and prevents leaking for a wide range of applications such as plumbing, machinery, hydraulic and pneumatic repairs, etc.

NOTE:Please confirm the required size and material before purchase, and install it in the right place.
