ORK Custom Nano Spray Double PTFE Coating on FKM O-Ring Seals
Customer's First Choice
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.

*Service Temperature
For general type FKM the service temperature is better limited to
approximately from -26 C to 232 C in static
applications, though the service temperature can arrive to 275 C at
short time In dynamic applications, it is
suitable between -15 C and 200 C.
*Application
Because FKM has excellent resistance of high temperature, oil,
solvent, flame, chemicals and weathering, it is
usually applied in automotive, chemical processing, aerospace and
many other industries.
