What is EPDM o-ring?
EPDM o-rings, or ethylene propylene o-rings, are a family of synthetic elastomers with lower cost steam and chemical resistance, particularly for applications involving solvents, acids and other mild chemicals.
What is NBR o-ring?
Nitrile rubber (NBR) o-rings, also known as Buna-N, are one of the most commonly used sealing elastomers due to resistance to petroleum-based fuels and lubricants and its relatively low price. Nitrile elastomers are copolymers of acrylonitrile and butadiene. There are a number of common variations of nitrile compounds.
What are EPDM O-rings used for?
EPDM o-rings, gaskets, and seals are commonly used in automotive manufacturing, medical devices, household appliances, water and wastewater systems, and other challenging applications. In other forms, EPDM rubber is used for everything from garden hose to roofing membranes to speaker components.
What is NBR gasket material?
NBR Rubber – Nitrile Gasket Material NBR is the abbreviation for nitrile butadiene rubber. This is a synthetic rubber that was developed during the 1930s. It is fabricated through the co-polymerization of acrylonitrile (ACN) (polar building block) and 1.3-butadine (nonpolar building block).
What color is EPDM O-rings?
Color: EPDM O-rings can be manufactured in Black brown, green, white, rust, yellow, blue, red, orange, purple and gray are available, or any other color. Application: EPDM O-rings are widely used in phosphate-ester based hydraulic fluids and glycol based brake fluids systems.
What does NBR rubber stand for?
nitrile-butadiene rubber
nitrile rubber (NBR), also called nitrile-butadiene rubber, an oil-resistant synthetic rubber produced from a copolymer of acrylonitrile and butadiene. Its main applications are in fuel hoses, gaskets, rollers, and other products in which oil resistance is required.
How long do EPDM O-rings last?

Can you use wd40 on rubber seals?
WD-40 Specialist silicone lubricant helps keep rubber components safe. The lubricant can withstand temperature from -35°C to +200°C. The lubricant protects rubber parts from attracting dust and prevents moisture. Give the rubber seals at least an hour to settle properly and then apply the lubricant.
Can O-rings dry out?
Unfortunately, many of these traditional choices also have caused health and safety concerns combined with damage to the rubber O-ring. Petroleum-based products can cause elastomeric rubber to swell or dry out.
What are EPDM seals?
EPDM stands for Ethylene Propylene Diene Monomer, which is a type of synthetic rubber commonly used outdoors for roofing, window and door seals. EPDM Membrane creates an airtight and weathertight seal and can be used for a wide variety of applications such as glass protection.
Is Buna-N the same as NBR?
Acrylonitrile Butadiene Rubber (NBR) or Nitrile rubber is one of the most popular compounds for automotive applications. It also is well known as Buna-N. This name came from one of the first base polymers patented in 1934, therefore people commonly use this name for all classes for Nitrile to this day.
Is PTFE the same as EPDM?
EPDM is softer and performs better as a sealing material (it conforms better to rough surface finishes). Teflon is stiffer and slicker, therefore it may perform better in a dynamic or abrasive application. Both could care less about sea water in terms of chemical assault or corrosion.
