O-RINGS

Product Description

ORINGS

The use of O-rings extends to many fields. The main function that characterizes this type of joint is its ability to maintain the seal, preventing the mixture of liquids and gases. Such meetings are characterized by their versatility and resistance to high temperatures and pressures. The type of elastomer used in their manufacture can vary.

We can offer the O-rings in a wide range of materials:

Buna-N / Nitrile (NBR): The standard material for O-rings. For general purposes. Mineral oils and greases, derivative of the plants and animals, air instalations, aliphatic hydrocarbons, dilute acids.Working temperature: **0ºC until ***0ºC. Water to*0ºC.

Ethylene-Propylene (EPDM): Hot water and steam, hydraulic fluids, brake fluids, alcohols and ketones, refrigerants, Cleaning products, ozone. Working temperature: **0ºC until ***0ºC.

Fluorocarbon / VITON (FKM): High chemical resistance. oils, gasoline, concentrated acids, solvents, ozone, oxygen. Working temperature: **0ºC hasta ***0ºC.

The terms FPM, FKM and Viton® very often cause confusion and lead to incorrect interpretations. All of these designations actually stand for one single base material:fluoro rubber.

FPM is the international abbreviation according to DIN/ISO, whereas FKM is the short form for the fluoroelastomer category according to the American standard ASTM.
Viton® is the registered trade mark of DuPont Performance Elastomers.

Hydrogenated Nitrile (HNBR): Aliphatic hydrocarbons, refrigerants, ozone. Working temperature: **0ºC hasta ***0ºC.

Fluorosilicone (FMQ, FVMQ): Mineral oils and greases, derivative of the plants and animals, aromatic hydrocarbons,oxygen, ozone, hot air, water vapor, Envejecimiento. Temperatura de trabajo: **0ºC hasta ***0ºC.

Perfluorinated Elastomer / Kalrez (FFKM): It is the elastomer that offers greater chemical compatibility. Aliphatic and aromatic chlorinated hydrocarbons, organic acids, polar solvents. Working temperature: **0 to + **0°C.

Chloroprene / Neoprene (CR): The chlorine atom confers increased resistance to oils, approximately Natural Rubber and Nitrile, this is often sufficient for many working aplicaciones. Temperature: **5 to ***0.

Polyurethane (AU): Polyurethane O-rings are especially suitable for carrying out applications where loads involved dinmicas.Entre such applications include, for example, water services, tires and a wide variety of critical applications. In many cases polyurethane o-rings are used instead of NBR, due to its high mechanical strength. Working temperature: **0 to + **0C.

The range of hardness varies between *0Sh and *0sh, and there is the possibility to manufacture them in colors according to RAL / PANTONE

O-rings certifications: FDA, WRAS, NSF, KTW, UL, CLP (ACS), W**0, DWGW (EN**9 / EN**4 / EN**1), on demand.

Also joints made from Orong cord, performing the vulcanized or glued joints, thus being able to obtain O-rings joints of all sizes.
