What does an O ring do?

What are o rings used for? O rings are used to block a path which may otherwise allow a liquid or a gas to escape. The o ring is placed into a groove to secure them in place, and then compressed between two surfaces.

What are blue O rings used for?

static sealing applications
This material is ideal for static sealing applications and is widely used by the aerospace industry. Available in standard blue 70 durometer or custom colors. Neoprene/Chloroprene O-Ring Material: A synthetic rubber with excellent weather resistance and good heat and abrasion resistance.

Are all O rings the same?

Whether sold individually, in large wholesale batches or – as is increasingly common – as part of a highly flexible range of o-ring kits, the basic form and role of o-rings are generally the same across the board.

What is the difference between black O-rings and green O-rings?

Difference between black o rings and green o rings Black o rings are primarily neoprene or Nitrile or, in some cases, a mix of the two materials. Green o rings are hydrogenated Nitrile, also known as highly saturated Nitrile, or more commonly known as HNBR.

Do O-rings go bad?

When they fail, it’s usually because of the combined adverse effects of several environmental factors. The most common causes of O-Ring failures include: Improper gland design, allowing for too much or too little compression, not enough for seal expansion and tolerance stack-up.

What O rings are Fuel Safe?

Buna (Nitrile or NBR) O-rings: general purpose sealing Buna O-rings, also known as nitrile or NBR O-rings, offer excellent sealing and mechanical properties at a low cost. Buna O-rings have resistance to common lubricants and are recommended for crude oil, gasoline, propane, petroleum oils and water.
