About this item

  • Made of Viton (fluorocarbon elastomer) for use with a variety of chemicals and fuels
  • Round cross-section to provide a seal between cylindrical overlapping surfaces
  • Can be used across a wide temperature range from -15 degrees F (-26 degrees C) to 400 degrees F (205 degrees C)
  • Durometer (hardness) of 75A for resistance to penetration
  • Meets standards defined by Aerospace Standard AS568A


This Viton O-ring is black in color, round in shape, has a durometer (hardness) of 75A, and is designed for use in a wide variety of sealing applications.

Viton has excellent heat, fuel, and chemical resistance. Viton is acceptable for temperature applications between -15 degrees F (-26 degrees C) to 400 degrees F (205 degrees C). It is compatible for use with non-flammable hydraulic fuels, silicone oil, chlorinated hydrocarbons (trichlorethylene), fuels, aromatic hydrocarbons (benzene) and aliphatic hydrocarbons (propane), as well as high vacuum environments, ozone, and weathering. Viton is vulnerable to low molecular organic acids, ammonia gas, alkalis, amines, glycol-based brake fluids, and super-heated steam.

This Viton O-ring has a shore durometer of 75A. Shore durometer is the hardness of a material, and its resistance to permanent indentation. A higher durometer value indicates greater resistance to indentation on a scale of 0 to 100, with 100 indicating no indentation.

O-rings commonly provide a pressure and fluid seal between cylindrically shaped, overlapping mating surfaces and are commonly seen in engines, faucets, flanges, valves and various cylinders. They are circular in shape, with a round cross section and a hole in the center, similar to a doughnut. O-rings are available in various sizes, and can be ordered based on required nominal inside diameter (ID), outer diameter (OD), and cross-sectional (CS) diameter.

This Viton O-ring meets standards defined by Aerospace Standard AS568A, which is the Aerospace Size Standard for O-rings.

These orings fit perfectly for your old idi international diesel return line cups. If you get a cup kit, toss out the supplied orings and get these. They're more durable and handle the diesel fuel better with no more leaking.

If you are working with 12mm hard-line tubing with Barrow compression fittings, these orings work soooooo much better than the compression orings sent with the fitting. They give me the ability to really clamp down on my tubing, ensuring it doesn't pop out and blow all my coolant.They also work great as replacements for G1/4 fitting thread seals. A bit thicker than the ones I replaced, these seal up with a more positive squish and makes me more confident that it's not going to leak and ruin my expensive board. Highly recommended if you are a watercooler!

Exact o-ring for garden hose quick couplers either the brass or Gardena plastic ones. Local store sells 3 of them in a kit for $4.00, here I have 50

Great quality O-ring. Viton material is more durable than the typical Buna-N from hardware stores.
