Read on to find answers to some frequently asked questions about O-ring coatings.

What do you coat O-rings with?

O-ring coatings run the gamut, from simple soap and water to petroleum distillates and dry film lubricants. It depends on the application the O-rings are used for. You might need a different lubricant for a food production facility versus an off-shore petroleum rig

Industrial coatings for O-rings include:

  • PTFE
  • Xylan
  • Emralon Tm001
  • Molykote

Why do you need O-ring coatings?

There are many benefits from O-ring coatings, such as:

  • Increased safety, service life and functionality of O-rings (and hence your equipment).
  • Fewer breakdowns caused by O-rings.
  • Longer times between maintenance on items with O-rings.
  • Reduction of coefficient of friction, wear, abrasion, damage, and scuffing.
  • Decreased leakage by filling minuscule gaps between surfaces and the O-ring seal.

Why do companies use dry film lubricants for O-ring coatings?

The goal of applying a dry film lubricant to an O-ring is to protect your O-ring from:

  • Resistance
  • Compression
  • General wear and tear

Dry film lubricants are designed to rub off onto the component that the O-ring will come in contact with, thereby lubricating the O-ring and the contact surface simultaneously during use.

Why are different colors used for O-rings?

Companies use different colors for O-rings for different reasons, including:

  1. To distinguish one material from another on a production line. This is particularly important when trying to clean machinery or ascertain where possible breakdowns are coming from.
  2. To improve visibility of equipment. If your technicians require a quick way to determine what the equipment is or a type of feeder line, seeing a particular color offers an efficient protocol for identifying the equipment.
  3. Better appearance of equipment. Sometimes, companies simply want O-rings to stand out from the background colors of the equipment. Bright colors against dark backgrounds help staffers see where the O-rings are on the line without having to do a lot of searching.

How do you condition an O-ring?

You can condition an O-ring by adding a lubricant to it manually or by using dry film lubricants that work automatically during the machine’s operation.
