Black CR Abrasion-Resistance Neoprene O Seal Ring for Hose Seal
What is O Seal ring ?
1.The O-ring is an annular seal having an O-shaped cross section, the size of which is determined
by the inner diameter ID and the wire diameter CS.
2.O-ring size calculation: outer diameter = inner diameter + 2 x wire diameter (OD = ID + 2x CS).
3.The purpose of using O-ring seals is to prevent leakage and loss of liquids or gases.
4.O-rings are the most commonly used type of seal because of their simplicity, convenience, and
small installation space. As long as the groove design and material selection are correct, and the
operating conditions are within the temperature range of the rubber material, the seal can have a
long-term sealing effect in the static or dynamic seal.
The standard of O-rings mainly includes: national standard GB1235-76, national standard
GB3452.1-92; Japanese standard PTYPE, GTYPE, STYPE, SS/VTYPE, FTYPE; American standard
AS568, British standard series; European standard series
O-ring technical requirements include appearance requirements, dimensional requirements, and
material physical performance requirements.
Appearance requirements in line with GB/T3452.2-2007
Material requirements are in line with HG/T2579-2008
Dimensional requirements are in line with GB/T3452.1-2005

Neoprene or Polychloroprene is a group of synthetic rubbers which exhibit excellent chemical
constancy and maintain flexibility over a wide temperature range. Neoprene can be used in
a wide selection of applications, such as laptop sleeves, orthopedic braces, electrical insulation,
liquid, and sheet applied elastomeric membranes or flashings, and automotive fan belts. Its
chemical inertness makes it well suitable for industrial applications such as gaskets, hoses, and
corrosion-resistant coatings.
