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)

Polyurethane is an organic polymer. Polyurethanes are formed by reacting a polyol (an alcohol with more than two reactive

hydroxyl groups per molecule) with a diisocyanate or a polymeric isocyanate in the presence of suitable catalysts and additives.

Polyurethane is a widely used compound due to its superior strength, tear and abrasion resistance. Polyurethane also provides

excellent permeation resistance.

Features:

• Good hydraulic oil and gasoline resistance
• Resistant to pure aliphatic hydrocarbons (propane, butane, fuel)
• Resistance to mineral and silicone oils and greases
• Resistant to water, oxygen, ozone and aging
• Excellent tear and abrasion resistance
• Available in multiple types and compounds to meet performance and cost requirements
