Small Parts 049 Review by Jason Heiss

Dunno what to say about an o-ring, but they appear to be well-made, come nicely packaged, etc.

Small Parts 049 Review by A. J. Espinosa

One of the o-rings on my gravity bike stand broke, and I was scratching my head trying to figure out what would work as a replacement. I'm not even sure how I figured out that these things are called "o-rings," but I measured the inside diameter and gave this a shot.

The 1" ID fits snugly on my bike stand, and it's thicker and more durable than the o-rings that came with it! I hopefully won't have to replace these for a while, but at least I have a cheap source of replacements now.

Small Parts 049::Description

This Viton quad-ring is black in color, is used in a wide variety of static and dynamic sealing applications, and has a durometer of 75A.

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 quad-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.

Quad-rings, also called X-rings, provide a pressure and fluid seal between overlapping surfaces in static and dynamic sealing applications, and are commonly used in engines, faucets, flanges, valves and various cylinders. They have a four-lobe design, to provide two contact points, which results in resistance to friction, twisting, and leakage. Quad-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 quad-ring meets standards defined by Aerospace Standard AS568A, which is the Aerospace Size Standard for O-rings.
