Additional Benefits to PTFE O-Rings PTFE does not swell due to moisture absorption. PTFE is not susceptible to explosive decompression. Virgin PTFE is FDA Compliant.

What is the difference between nitrile and Viton O-rings?

Temperature: Viton® seals can withstand temperatures up between -20°C to 210°C. This makes Viton® far superior to Nitrile in these regards. They are also designed to resist most oils and lubricants, more importantly petroleum-based lubricants.

What is the best O-ring material for hydraulic fluid?

Nitrile
Nitrile (Buna-N) is a general purpose material suited for petroleum oils, water, and some hydraulic fluids. It is an inexpensive popular seal that is also resistant to tears and abrasive treatment and will function in temperatures between -35 degrees Fahrenheit and 250 degrees Fahrenheit.

Which is better PTFE or Viton?

Viton vs Teflon (PTFE) – Viton offers a greater temperature resistance but falls short of Teflons(PTFE) chemical resistance. Also, Teflon is slightly less thermally resistant but offers much more in the way of non-adhesive properties.

Is silicone good for O-rings?

The solution is: Use silicone lubricant for o-rings and seals to be safe. Silicone lubricant is waterproofing and lubricating. It costs $10 for a small tube and is available at all auto parts stores. Be safe, use silicone grease on your o-rings and rubber seals in pressure washer wands, hoses and pumps.

What is difference between EPDM and nitrile rubber?

What is the difference between NBR and EPDM? NBR and EPDM are two types of rubber materials. NBR stands for nitrile butadiene rubber, while EPDM stands for ethylene propylene diene monomer rubber. The main difference between NBR and EPDM is that NBR is a non-aromatic polymer compound while EPDM is an aromatic polymer.

What material is best for O ring?

These parameters will determine the best suited material for an application. O-rings are available in several different materials such as PTFE, Nitrile (Buna), Neoprene, EPDM Rubber and Fluorocarbon (Viton). Kalrez ® o-rings and Silicone seals are also widely used high temperature applications.

What material is a gasket made of?

Gaskets are normally made from a flat material, a sheet such as paper, rubber, silicone, metal, cork, felt, neoprene, nitrile rubber, fiberglass, polytetrafluoroethylene (otherwise known as PTFE or Teflon) or a plastic polymer (such as polychlorotrifluoroethylene).

Where and why are O rings used?

O rings are made from elastomers and are flexible by nature. In short, o rings are seals for liquids and gases that work quite effectively. The main places where you can find these are engines, compressors, refrigerators and boilers. They are mainly used in processes where there is a high temperature or pressure.

How to measure an O-ring?

Place the O-ring on a clean, flat, level surface.
