Red Elastomer Material EPDM FKM NBR 70 Shore Standard O Ring for Sealing Element Silicone High Seals Custom Size
Type: O Ring
Size: ID X CS, OD=ID + 2XCS
An o-ring is a simple and versatile ring-shaped packing or sealing device with a circular cross
section (from which the "O" in its name is derived). The purpose of using O-ring seals is to
prevent leakage and loss of liquids or gases. They 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 size of o-ring is determined by the inner diameter ID and the wire diameter CS. O-ring
size calculation: outer diameter = inner diameter + 2 x wire diameter (OD = ID + 2x CS).
O-Ring Advantages:
1. O-Rings offer an efficient and economical sealing element for a wide range of static or dynamic
applications.
2. O-Ring sizes are defined by the inner diameter-ID and the cross section-CS, our o-ring Inner
Diameter can be from 0.5mm to 1500mm.
3. Standard sizes such as AS568(PARKER sizes), JIS(P TYPE, G TYPE, S TYPE, V TYPE, F TYPE
sizes), BS1516 sizes Metric sizes as well as non-standard sizes are all avaiblabe.
4. We have more than 2000 o-ring mould toolings, so you could get any size here without set-up
or tooling charge. Huge inventory of o-rings can meet your urgent requiremnets.
5. A very wide range of elastomer material can be selected, main material: NBR(BUNA-N, Nitrile),
FKM(FKM), Silicone(VMQ), HNBR,FFKM, EPDM, PU(Polyurethane, urethane), Fluorosilicone(FVMQ),
Neoprene(CR) and so on. Hardness of material can be from 40 ShoreA(Durometer) to 90 ShoreA
(Durometer)
O-Ring Technical requirements:
Appearance meets GB/T3452.2-2007 Material meets HG/T2579-2008 Size meets GB/T3452.1-2005
In addition, all our products are ROHS and REACH Compliant (we mainly export products to USA and
Europe market).
O-Ring Features:
1. Good sealing solution, long service life.
2. Easy installation reduces risk.
3. Working in various medium based on different elastomer material.
