FAQ:
Q: What size are O rings?
A: The standard sizes used by Parco and the other major O-ring manufacturers in the United States are defined by Aerospace Standard AS568. There are 369 standard sizes of O-rings with inside diameters ranging from 0.029 to 25.940 inches and cross sections ranging from 0.040 to 0.275 inch.
Q: How often do you change O rings?
A: As far as the others o-rings, some replace them every two-years, some never. If there isn’t a leak and you have no accuracy issues, I would leave the alone. If you are already inside your rifle for some reason, you may want to replace them anyway since o-rings are not that expensive. Always use some silicone grease to make them last longer.
Q: What is the purpose of an O ring?
A: Generally, the purpose of O-Rings is to block a pathway that fluid or air may escape through, as it is a sealing device. When squeezing the O-Ring between two surfaces, it takes up the clearance and blocks the pathway that the fluid or air wants to escape through. Also, the rubber of an O-Ring has muscle-memory when squeezed.
Q: Are O rings and gaskets same?
A: O-rings are technically considered a gasket, however, the material it is made from differs from most gaskets. The O-ring’s cross section can be round or square and is commonly made from neoprene, although O-rings can be made from rubber or other synthetics.
